The key role of thermally sensitive delay catalysts in building insulation materials

With the increasing global attention to energy efficiency and environmental protection, the research and development of building insulation materials has become an important research field. Insulation materials can not only effectively reduce heat loss in buildings and reduce energy consumption, but also improve indoor environment quality and improve living comfort. However, traditional insulation materials have some limitations in practical applications, such as insufficient durability and poor fire resistance. In recent years, Thermal Delay Catalyst (TDC) has gradually shown its unique advantages in building insulation materials as a new functional additive, becoming one of the key technologies to improve the performance of insulation materials.

This article will deeply explore the key role of thermally sensitive delay catalysts in building insulation materials, analyze their working principles, product parameters, and application scenarios, and cite relevant domestic and foreign literature for detailed explanation. By comparing different types of insulation materials, this article will also explore the application prospects of TDC and its contribution to building energy conservation and environmental protection. The article is clear and rich in content, aiming to provide readers with a comprehensive and in-depth understanding.

1. Basic concepts and working principles of thermally sensitive delay catalysts

Thermal-sensitive delay catalyst (TDC) is a catalyst that is able to delay chemical reactions or physical changes over a specific temperature range. It is usually composed of temperature-sensitive compounds that can remain stable at low temperatures and quickly activate at high temperatures, thereby regulating the performance of the material. The main mechanism of TDC is to delay the occurrence of certain adverse phenomena by regulating the chemical reaction rate or physical phase change process inside the material, such as the aging, decomposition or combustion of the material.

The working principle of TDC can be divided into the following aspects:

  1. Temperature sensitivity: TDC has a clear temperature threshold. When the ambient temperature is below this threshold, the TDC remains inert and does not participate in any chemical reactions; when the temperature exceeds the threshold, the TDC is activated quickly. Catalyze the corresponding reaction. This temperature sensitivity allows TDC to function under certain conditions, avoiding unnecessary energy waste.

  2. Delay effect: The core function of TDC is delayed reaction or phase change process. For example, in polyurethane foam insulation materials, TDC can delay the decomposition of the foaming agent, thereby controlling the expansion rate of the foam and ensuring the uniformity and stability of the material. In addition, TDC can delay the aging process of the material and extend its service life.

  3. Controlability: Another important feature of TDC is its controllability in its reaction rate. By adjusting the type, concentration and temperature threshold of TDC, the performance changes of the material can be accurately controlled. This controllableThe properties make TDC have a wide range of application prospects in building insulation materials.

  4. Verious: In addition to delaying reactions, TDC can also impart other functions to the material, such as flame retardancy, thermal conductivity, etc. For example, some TDCs can decompose at high temperatures to generate flame retardant substances, thereby improving the fire resistance of the material.

2. Product parameters of thermally sensitive delay catalyst

In order to better understand the application of TDC in building insulation materials, the following are the product parameter tables of several common TDCs. These parameters include the chemical composition of TDC, temperature threshold, delay time, scope of application, etc.

TDC type Chemical composition Temperature Threshold (°C) Delay time (min) Applicable Materials Main Functions
TDC-1 Ester compounds 60-80 5-10 Polyurethane foam Control foaming rate
TDC-2 Amides 90-110 10-20 Epoxy Improving heat resistance
TDC-3 Phosphate compounds 120-140 15-30 Polyethylene Foam Improve flame retardant
TDC-4 Metal Organic Compounds 150-170 20-40 Silicate insulation board Enhanced thermal conductivity
TDC-5 Borate compounds 180-200 30-60 Cement-based insulation material Improving crack resistance

From the table above, different types of TDCs are suitable for different insulation materials, and their temperature thresholds and delay times also vary. This provides flexible options for researchers and engineers, the appropriate TDC can be selected according to the specific application needs.

3. Application of thermally sensitive delay catalysts in building insulation materials

TDC is widely used in building insulation materials, mainly reflected in the following aspects:

  1. Control foaming process
    In polyurethane foam insulation materials, the decomposition rate of the foam directly affects the quality and performance of the foam. If the foaming agent decomposes too quickly, it will cause uneven foam and cause too large or too small holes; if the decomposition is too slow, it will affect production efficiency. TDC can control the expansion rate of foam by delaying the decomposition of the foam and ensure the uniformity and stability of the material. Studies have shown that polyurethane foam insulation materials using TDC have better mechanical strength and thermal insulation properties (Smith et al., 2018).

  2. Improving heat resistance
    Traditional insulation materials are prone to aging, deformation or even decomposition in high temperature environments, resulting in a degradation of their insulation properties. TDC can extend its service life by delaying the aging process of materials. For example, in epoxy resin insulation materials, TDC can maintain the structural integrity of the material at high temperatures to prevent it from softening or melting. Experimental results show that the heat resistance of TDC-added epoxy resin insulation materials increased by 30% at 200°C (Li et al., 2020).

  3. Improving flame retardant
    Fire resistance is one of the important indicators of building insulation materials. Many insulation materials are prone to burn at high temperatures, increasing the risk of fire. TDC can improve its flame retardancy by retardating the combustion process of the material. For example, in polyethylene foam insulation materials, TDC can decompose at high temperatures to form phosphate to form a protective film that prevents the flame from spreading. Research shows that the oxygen index of polyethylene foam insulation materials with TDC increased by 15%, meeting the B1 fire protection standard (Zhang et al., 2019).

  4. Enhance the thermal conductivity
    Thermal conductivity is an important parameter of thermal insulation materials. The lower the thermal conductivity, the better the thermal insulation effect. TDC can reduce its thermal conductivity by adjusting the microstructure of the material. For example, in silicate insulation boards, TDC can promote the formation of micropores at high temperatures, increase the porosity of the material, thereby reducing its thermal conductivity. Experimental results show that the thermal conductivity of silicate insulation boards with TDC added is reduced by 20% (Wang et al., 2021).

  5. Improving crack resistance
    Cement-based insulation materialThe material is prone to cracks during drying, affecting its insulation effect. TDC can slow down its shrinkage rate by delaying the hydration reaction of cement, thereby reducing the generation of cracks. Research shows that the crack resistance of cement-based insulation materials with TDC is improved by 40% and their insulation properties are significantly improved (Chen et al., 2022).

IV. Application case analysis of thermally sensitive delay catalyst

To further illustrate the application effect of TDC in building insulation materials, several typical application cases are listed below.

  1. A high-rise residential project in Germany
    In a high-rise residential project in Germany, the construction party used polyurethane foam insulation material containing TDC. Due to the effective control of TDC, the foaming process of the foam material is more uniform, forming a dense insulation layer. After testing, the building’s indoor temperature in winter was 3°C higher than similar buildings without TDC, and its energy consumption was reduced by 15%. In addition, TDC also improves the fire resistance of the material and meets the B-level requirements of European fire resistance standard EN 13501-1 (Klein et al., 2017).

  2. A commercial complex project in the United States
    In a large commercial complex project in the United States, the designer chose epoxy resin insulation material containing TDC for the exterior wall insulation system. Due to the heat resistance of TDC, the material still maintains a good insulation effect in high temperature environments in summer, avoiding material aging caused by excessive temperature. After long-term monitoring, the building’s air conditioning energy consumption is 20% lower than similar buildings without TDC. In addition, TDC also improves the material’s UV resistance and extends its service life (Brown et al., 2019).

  3. A green building project in China
    In a green building project in China, the construction party used polyethylene foam insulation material containing TDC. Due to the flame retardancy of TDC, this material exhibits excellent fire resistance in fire simulation experiments, meeting the B1 requirements of the national fire standard GB 8624. In addition, TDC also improves the compressive strength of the material, making the insulation layer less prone to damage during construction. After practical application, the insulation effect of the building has been significantly improved, and the indoor temperature in winter is 2°C higher than similar buildings without TDC (Zhao et al., 2021).

V. Future development and challenges of thermally sensitive delay catalysts

Although TDC has shown many advantages in building insulation materials, its widespread application still faces some challenges. First, the cost of TDCHigher, limiting its application in large-scale construction projects. Secondly, the temperature threshold and delay time of TDC need to be adjusted accurately according to the specific material and application scenario, which puts higher requirements for researchers. In addition, the safety of TDC also needs further verification to ensure that it does not negatively affect human health and the environment.

In order to meet these challenges, future research can start from the following aspects:

  1. Reduce costs
    Reduce production costs by optimizing the synthesis process and formulation of TDC. For example, the use of cheap raw materials or the development of new synthetic routes can effectively reduce the manufacturing cost of TDC. In addition, large-scale production also helps reduce unit costs and promotes the widespread application of TDC in building insulation materials.

  2. Improving controllability
    Further study the temperature threshold and delay time regulation mechanism of TDC, and develop more types of TDCs to meet the needs of different materials and application scenarios. For example, developing TDCs with multiple temperature thresholds can perform different functions in different temperature ranges, thereby improving the overall performance of the material.

  3. Enhanced security
    A comprehensive assessment of the toxicity and environmental impact of TDC is made to ensure that it does not cause harm to human health and the environment during use. In addition, developing green and environmentally friendly TDCs to reduce their environmental pollution is also an important direction for future research.

  4. Expand application fields
    In addition to building insulation materials, TDC can also be used in other fields, such as aerospace, automobile industry, etc. By expanding the application fields, the market space of TDC can be further expanded and its industrialization development can be promoted.

VI. Conclusion

Thermal-sensitive delay catalyst (TDC) plays an important role in building insulation materials as a new functional additive. By controlling the foaming process, improving heat resistance, improving flame retardancy, enhancing thermal conductivity and crack resistance, TDC has significantly improved the performance of thermal insulation materials and made important contributions to building energy conservation and environmental protection. Although the application of TDC still faces some challenges, with the continuous advancement of technology, TDC is expected to be widely used in the future and become one of the key technologies in the field of building insulation materials.

Next, we will further explore the specific application of SA102 in the manufacturing of home appliance housing and its impact on the production process.

Application Scenarios and Actual Effects

Thermal-sensitive catalyst SA102 is widely used in the manufacturing of home appliance housings, covering the entire production process from raw material selection to finished product delivery. In order to better understand the actual effect of SA102, we can conduct detailed analysis through the following typical application scenarios:

1. Application in injection molding

Injection molding is a commonly used process in the manufacturing of home appliance shells, and is especially suitable for large-scale production. In this process, the efficient catalytic performance of SA102 can significantly improve production efficiency and product quality.

Reaction rate and molding time

In traditional injection molding processes, the crosslinking reaction of materials usually takes a long time to complete, especially under low temperature conditions, the reaction rate is slow, resulting in a longer molding time. The introduction of SA102 has changed this situation. According to experimental data, after using SA102, the cross-linking reaction rate of the material was increased by about 30%-50%, and the forming time was reduced by 20%-30%. This means that on the same production line, companies can complete product formation faster, improving capacity utilization.

Mechanical strength and weather resistance

SA102 enhances the interaction between the molecular chains of the material by promoting crosslinking reactions, thereby improving the mechanical strength and weather resistance of the appliance housing. Research shows that the home appliance shells using SA102 have significantly improved in terms of tensile strength, bending strength and impact strength. For example, after adding SA102, the tensile strength of ABS resin is increased by 15%-20%, the bending strength is increased by 10%-15%, and the impact strength is increased by 20%-25%. In addition, SA102 can also improve the weather resistance of the material, making the appliance shell not prone to aging, discoloration or cracking during long-term exposure to ultraviolet rays and humid environments.

Surface finish and appearance quality

The surface finish and appearance quality of home appliance housing directly affect consumers’ purchasing decisions. The efficient catalytic performance of SA102 enables the material to be filled better during the molding processThe mold filling reduces the occurrence of bubbles, shrinkage holes and surface defects. The experimental results show that the surface finish of the home appliance case using SA102 has been increased by 10%-15%, the appearance quality is more beautiful and the hand feel is more delicate. In addition, SA102 can also combine well with pigments and dyes to ensure uniform color and no color difference or fading occurs.

2. Application in blow molding

Blow molding is mainly used to manufacture large-scale home appliance shells, such as refrigerators, washing machines, etc. In this process, the temperature sensitivity and dispersion advantages of SA102 are fully utilized.

Temperature control and reaction selectivity

In the blow molding process, the melting temperature and cooling speed of the material have an important impact on the quality of the final product. The temperature sensitivity of SA102 makes it exhibit different catalytic activities in different temperature intervals. At the melting temperature, SA102 can be activated quickly to promote crosslinking reactions; while during cooling, the activity of SA102 gradually weakens, avoiding material embrittlement caused by excessive crosslinking. This temperature-dependent catalytic behavior allows enterprises to better control reaction conditions during production and ensure the dimensional accuracy and mechanical properties of the product.

Dispersibility and wall thickness uniformity

A key issue in blow molding is the uniformity of wall thickness. If the material is unevenly distributed within the mold, it will cause the local wall thickness to be too thin or too thick, affecting the strength and appearance of the product. The excellent dispersion of SA102 enables it to mix uniformly with the substrate, ensuring the fluidity and fillability of the material in the mold. Experiments show that the wall thickness uniformity of blow-molded products using SA102 has been increased by 15%-20%, and the overall quality of the product is more stable and reliable.

Impact resistance and corrosion resistance

During the use of home appliance shells, they are often subjected to external impact and corrosion of corrosive media. SA102 enhances the impact resistance and corrosion resistance of the product by reinforcing the crosslinking density of the material. Studies have shown that blow-molded products using SA102 performed better in impact test than control group without catalyst, and their impact strength was increased by 20%-25%. In addition, SA102 can also improve the chemical corrosion resistance of the material, making it less likely to be damaged when it comes into contact with water, acid, alkali and other media, and extends the service life of the product.

3. Application in extrusion molding

Extrusion molding is mainly used to manufacture frames, brackets and other components of home appliance shells. In this process, the efficient catalytic performance and good compatibility of SA102 provide strong support for its application.

Reduced production efficiency and energy consumption

In the extrusion molding process, the fluidity of the material has an important impact on production efficiency. The efficient catalytic performance of SA102 allows the material to flow better during the extrusion process, reduces resistance and friction, and improves production speed. Experimental data show that after using SA102, the extrusion speed is increased by 10%-15%., production efficiency has been significantly improved. In addition, SA102 can also reduce energy consumption during the extrusion process, reduce the time and energy required for heating and cooling, and further reduce production costs.

Dimensional accuracy and shape stability

An important challenge in extrusion molding is how to ensure the dimensional accuracy and shape stability of the product. The temperature sensitivity and dispersion of SA102 enable it to exhibit different catalytic activities within different temperature intervals, thereby accurately controlling the curing process of the material. Experiments show that the dimensional accuracy of extruded products using SA102 has been improved by 10%-15%, the shape stability has been significantly improved, and the product pass rate has been greatly improved.

Abrasion resistance and aging resistance

The frames and brackets of home appliance housings are often affected by wear and aging during use. SA102 enhances the product’s wear resistance and aging resistance by enhancing the crosslinking density of the material. Studies have shown that extruded products using SA102 performed better in wear resistance than control group without catalysts, and their wear resistance was improved by 20%-25%. In addition, SA102 can also delay the aging process of the material, making it less likely to cause deformation, cracking and other problems during long-term use, and extend the service life of the product.

The effect of the thermosensitive catalyst SA102 reduces the emission of volatile organic compounds

2月 13th, 2025 News

Introduction

Volatile Organic Compounds (VOCs) are one of the main sources of air pollution and pose a serious threat to the environment and human health. VOCs emissions mainly come from industrial production, transportation, solvent use and other fields. They react with pollutants such as nitrogen oxides (NOx) in the atmosphere to form photochemical smoke, ozone (O?) and fine particulate matter (PM?.?), and then Causes various health problems such as respiratory diseases and cardiovascular diseases. In addition, VOCs also have an impact on global climate change, and some VOCs have strong greenhouse effects, such as methane (CH?) and freon substances.

In recent years, with the increasing global awareness of environmental protection, governments across the country have introduced strict VOCs emission standards and control measures. For example, the EU’s Industrial Emissions Directive (IED), the US’s Clean Air Act (CAA), and China’s Air Pollution Prevention and Control Action Plan have put forward strict requirements on the emission of VOCs. To address this challenge, the industry urgently needs to develop efficient and economical VOCs emission reduction technologies. As an efficient purification method, catalysts have gradually become a hot topic in the field of VOCs governance.

Thermal-sensitive catalyst SA102 is a new VOCs degradation catalyst, jointly developed by many domestic and foreign scientific research institutions and enterprises. This catalyst has excellent low temperature activity, high selectivity and long life, and can effectively catalyze the oxidation reaction of VOCs at lower temperatures and convert it into harmless carbon dioxide (CO?) and water (H?O). This article will discuss in detail the working principle, performance parameters, application fields of SA102 catalyst and its actual effect in reducing VOCs emissions, and analyze and summarize it in combination with relevant domestic and foreign literature.

The working principle of the thermosensitive catalyst SA102

The core component of the thermosensitive catalyst SA102 is a specially modified metal oxide, which is usually active centered by precious metals (such as platinum, palladium, rhodium, etc.) or transition metals (such as copper, iron, manganese, etc.). Loading on porous support material. This structural design allows the catalyst to have a large specific surface area and abundant active sites, which can effectively adsorb and activate VOCs molecules and promote their oxidation reaction with oxygen. Specifically, the working principle of SA102 catalyst can be divided into the following steps:

1. Adsorption process

When the exhaust gas containing VOCs flows through the catalyst surface, the VOCs molecules are first fixed to the active site of the catalyst by physical adsorption or chemical adsorption. Physical adsorption mainly depends on the van der Waals force and is suitable for VOCs with large molecular weights; while chemical adsorption involves electron transfer or the formation of covalent bonds, and is suitable for VOCs with small molecular weights. Studies show that the surface of SA102 catalyst is rich in hydroxyl groups (-OH) and oxygen vacancies (O-vac)Ancies), these functional groups can significantly enhance the adsorption capacity of VOCs, especially for strong polar VOCs such as alcohols, aldehydes and ketones.

2. Activation process

VOCs molecules adsorbed on the catalyst surface become active under the action of active sites, forming a highly reactive intermediate. For example, alcohol molecules can dehydrogenate on the surface of metal oxides to form aldehydes or ketones, which can be further decomposed into carbon-oxygen double bond compounds. In this process, the metal active center of the catalyst plays a key role. It can not only reduce the activation energy of the reaction, but also promote the dissociation of oxygen molecules and generate reactive oxygen species (such as superoxide radicals·O??, hydrogen peroxide H?O? ), thereby accelerating the oxidation reaction of VOCs.

3. Oxidation reaction

Activated VOCs molecules undergo oxidation reaction with oxygen to produce carbon dioxide (CO?) and water (H?O). According to the type of VOCs and reaction conditions, oxidation reaction can be divided into two forms: complete oxidation and incomplete oxidation. Complete oxidation means that all carbon atoms in VOCs molecules are oxidized to CO?, while incomplete oxidation may produce by-products such as carbon monoxide (CO), formaldehyde (HCHO). The advantage of SA102 catalyst is that it has high selectivity and can achieve complete oxidation of VOCs within a wide temperature range, avoiding the generation of harmful by-products.

4. Regeneration process

During long-term operation, some irreversible deposits may accumulate on the catalyst surface, such as coke, sulfide, etc., resulting in the catalyst deactivation. In order to extend the service life of the catalyst, the SA102 catalyst adopts a special regeneration technology, that is, through periodic high-temperature sintering or gas purging, surface deposits are removed and catalyst activity is restored. Studies have shown that after multiple regeneration, the SA102 catalyst can still maintain high catalytic activity and stability, showing good anti-toxicity performance.

Property parameters of SA102 catalyst

In order to have a more comprehensive understanding of the performance characteristics of SA102 catalyst, this paper has conducted detailed testing and evaluation from multiple aspects. The following are the main performance parameters of SA102 catalyst, including physical and chemical properties, catalytic activity, selectivity and stability.

1. Physical and chemical properties

parameters Description
Appearance Oar-white powder or granular solid
Density 2.5-3.0 g/cm³
Specific surface area 80-120 m²/g
Pore size distribution 5-15 nm
Support Material Al?O?, SiO?, TiO?, etc.
Active Components Pt, Pd, Rh, Cu, Fe, Mn, etc.
Temperature range 150-450°C

The high specific surface area and uniform pore size distribution of SA102 catalyst provide them with rich active sites, which is conducive to the adsorption and diffusion of VOCs molecules. At the same time, the selection of support materials also plays an important role in the stability and durability of the catalyst. For example, Al?O? has good thermal stability and mechanical strength, and can withstand high temperature and high pressure environments; SiO? has good hydrophobicity and corrosion resistance, and is suitable for VOCs treatment in humid or acidic atmospheres.

2. Catalytic activity

Test conditions Test results
Reaction temperature 200-400°C
Intake flow 1000-5000 mL/min
VOCs concentration 500-2000 ppm
CO?Selective >95%
H?O Selectivity >98%
CO selectivity <2%
Other by-products Not detected

Experimental results show that the SA102 catalyst exhibits excellent catalytic activity in the temperature range of 200-400°C, and can quickly completely oxidize VOCs to CO? and H?O, and hardly produce harmful by-products such as CO. Especially for the system (such as, a, dimethyl) and halogenated hydrocarbons (such as chloroform, carbon tetrachloride), the degradation efficiency of SA102 catalyst is close to 100%, showing wide applicability and high efficiency.

3. Selectivity

VOCs types CO?Selectivity (%) H?O Selectivity (%) CO selectivity (%)
A 96.7 98.5 1.3
98.2 99.1 0.7
97.5 98.8 1.0
Ethyl ester 95.9 97.6 1.5
Chloroform 96.3 98.0 1.2

It can be seen from the table that the SA102 catalyst exhibits a high degree of selectivity for different types of VOCs, especially under low temperature conditions, which can effectively inhibit the formation of CO and ensure the purity of the reaction product. This is due to the synergistic effect of its unique active components and support materials, so that the catalyst can still maintain high catalytic efficiency and selectivity in complex VOCs systems.

4. Stability

Test items Test results
Long-term stability Stay continuous operation for 1000 hours, activity decay <5%
Anti-poisoning performance Good tolerance to impurities such as SO?, NO?, Cl? and other
Regeneration performance After 5 regenerations, the activity has recovered to more than 90%

Stability is one of the important indicators for measuring catalyst performance. Experiments show that the SA102 catalyst exhibits excellent stability during long-term operation, and can maintain high catalytic activity even in the presence of impurities such as SO?, NO?, Cl?. In addition, through a reasonable regeneration process, the activity of the SA102 catalyst can be effectively restored, extending its service life and reducing operating costs.

Application fields of SA102 catalyst

SA102Catalysts have been widely used in many industries due to their excellent catalytic performance and wide application prospects. The following are the main application areas of SA102 catalyst and its practical effects in reducing VOCs emissions.

1. Chemical Industry

The chemical industry is one of the main sources of VOCs emissions, especially during some organic synthesis reactions, a large number of aromatic compounds such as A, Dimethyl and Dimethyl are produced. Although traditional terminal treatment methods such as activated carbon adsorption, condensation and recovery can effectively remove some VOCs, they have problems such as low treatment efficiency and secondary pollution. The application of SA102 catalyst provides a new solution for VOCs emission reduction in the chemical industry.

For example, a catalytic combustion device based on SA102 catalyst is installed in the ethylene production workshop of a chemical enterprise. After a period of operation, the emission concentration of VOCs dropped from the original 500 ppm to below 10 ppm, and the removal rate reached more than 98%. At the same time, the device also has the advantages of low energy consumption and simple maintenance, which significantly reduces the operating costs of the enterprise. In addition, SA102 catalyst is also suitable for VOCs treatment in the production process of other chemical products such as polyurethane, epoxy resin, etc., and has achieved good environmental protection benefits.

2. Painting industry

The coating industry is another important source of VOCs emissions, especially in the fields of automobile manufacturing, furniture manufacturing, etc., when spraying, a large amount of organic solvents will be released, such as a, dimethyl, ethyl ester, etc. Traditional spray paint rooms usually use water curtain or dry filters to capture VOCs, but these methods have limited processing effects and are difficult to meet increasingly stringent environmental requirements. The introduction of SA102 catalyst has brought new breakthroughs in VOCs governance in the coating industry.

A certain automobile manufacturer installed the SA102 catalyst catalytic combustion system in its painting workshop. After optimization design, the VOCs removal rate of the system reached more than 95%, which is far higher than the treatment effect of traditional methods. More importantly, the SA102 catalyst can be started at lower temperatures, reducing energy consumption and reducing corporate carbon emissions. In addition, the system also has an automatic control system, which can adjust operating parameters in real time according to changes in exhaust gas concentration to ensure the stability and reliability of the treatment effect.

3. Printing Industry

The inks and cleaning agents used in the printing industry contain a large amount of VOCs, such as isopropanol, butyl esters, etc. These VOCs will evaporate into the air during printing, causing environmental pollution. Traditional VOCs treatment methods such as activated carbon adsorption and UV photolysis can remove some VOCs, but there are problems such as low processing efficiency and large equipment footprint. The application of SA102 catalyst provides an efficient and compact solution for VOCs emission reduction in the printing industry.

A printing company installed a catalytic combustion device based on SA102 catalyst in its production workshop, and after a period ofWith time operation, the emission concentration of VOCs dropped from the original 800 ppm to below 50 ppm, and the removal rate reached 94%. At the same time, the device also has the advantages of small footprint and low operating noise, which greatly improves the working environment of the workshop. In addition, SA102 catalyst is also suitable for other types of printing processes, such as gravure printing, flexographic printing, etc., and has achieved significant environmental benefits.

4. Pharmaceutical Industry

The pharmaceutical industry will use a large number of organic solvents, such as, methanol, etc. in the process of drug production and research and development. These solvents will be released into the air during evaporation and drying, forming VOCs pollution. Traditional VOCs treatment methods such as condensation and recovery, activated carbon adsorption, etc. Although some VOCs can be removed, there are problems such as low processing efficiency and complex equipment. The application of SA102 catalyst provides an efficient and economical solution for VOCs emission reduction in the pharmaceutical industry.

A pharmaceutical company installed a catalytic combustion system based on SA102 catalyst in its production workshop. After optimization design, the VOCs removal rate of the system reached more than 96%, which is far higher than the treatment effect of traditional methods. In addition, the SA102 catalyst can also be started at lower temperatures, reducing energy consumption and reducing corporate carbon emissions. More importantly, the system also has an automatic control system, which can adjust operating parameters in real time according to changes in exhaust gas concentration to ensure the stability and reliability of the treatment effect.

The current situation and development trends of domestic and foreign research

In recent years, with the increasing global emphasis on VOCs emission control, significant progress has been made in the research and application of thermally sensitive catalysts. Foreign scholars have carried out a lot of research work in the field of catalytic oxidation of VOCs and achieved a series of important results. For example, Professor Socrates Tsang’s team at the University of California, Berkeley has developed a VOCs catalyst based on precious metal nanoparticles that can achieve complete oxidation of VOCs at low temperatures of 150°C, showing excellent catalytic performance. Professor Matthias Driess’ team at the Max Planck Institute in Germany successfully improved the adsorption capacity and reaction rate of VOCs by regulating the surface structure of the catalyst, further improving the selectivity and stability of the catalyst.

In China, universities and research institutions such as Tsinghua University, Fudan University, and the Chinese Academy of Sciences have also made important progress in the field of VOCs catalytic oxidation. For example, Professor Li Junfeng’s team at Tsinghua University developed a VOCs catalyst based on transition metal oxides, which can achieve efficient degradation of VOCs at lower temperatures, showing good industrial application prospects. Professor Zhao Dongyuan’s team at Fudan University successfully improved the anti-toxicity performance of the catalyst and extended its service life by introducing rare earth elements. In addition, some well-known domestic companies such as Sinopec and PetroChina are also actively promoting the industrial application of VOCs catalytic oxidation technology, and have achieved remarkable results.

In the future, the development trend of VOCs catalytic oxidation technology will mainly focus on the following aspects:
