The background and significance of low atomization and odorless catalyst
With the global emphasis on environmental protection and sustainable development, the environmental pressure faced by the chemical industry in the production process is increasing. Although traditional catalysts have played an important role in improving reaction efficiency and reducing costs, they have also brought some problems that cannot be ignored in practical applications, such as the emission of volatile organic compounds (VOCs), odor problems and human health. potential hazards. These problems not only affect the production environment, but may also have adverse effects on surrounding communities, which in turn triggers public opinion and legal risks.
A low atomization odorless catalyst is developed as a new catalyst to meet these challenges. Its core advantage is that it can significantly reduce or eliminate the atomization and odor problems caused by traditional catalysts during use while maintaining efficient catalytic performance. Atomization refers to the catalyst evaporating into a gaseous state under high temperature or high pressure conditions, forming tiny particles suspended in the air. These particles will not only affect the air quality, but may also cause corrosion and blockage to the equipment. The problem of odor is caused by the decomposition or evaporation of certain components in the catalyst during the reaction, producing a pungent odor, affecting the working environment and physical health of the operator.
The emergence of low atomization and odorless catalysts not only help improve the production environment and reduce environmental pollution, but also enhance the social responsibility image of enterprises, which is in line with the current global development trend of green chemical industry. In addition, the application of this type of catalyst can help enterprises meet increasingly stringent environmental protection regulations and reduce legal risks and economic costs caused by environmental pollution problems. Therefore, the research and application of low atomization odorless catalysts have important practical significance and broad market prospects.
Types and characteristics of traditional catalysts
Traditional catalysts are widely used in petrochemical, fine chemical, pharmaceutical, material synthesis and other fields. According to their physical form and chemical composition, they can be divided into three categories: liquid catalyst, solid catalyst and gas catalyst. Each type of catalyst has its own unique characteristics and application scenarios. The main characteristics of these three types of catalysts will be described in detail below.
1. Liquid Catalyst
Liquid catalysts are a type of catalysts that have been widely used for a long time. They usually exist in liquid form and can be evenly dispersed in the reaction system to provide efficient catalytic activity. Common liquid catalysts include base catalysts, metal salt solutions, homogeneous organometallic catalysts, etc.
-
Basic Catalyst: Base catalysts are one of the common liquid catalysts and are widely used in reactions such as esterification, hydrolysis, and hydrogenation. For example, strong sulfur and phosphorus are often used in esterification reactions, while alkaline substances such as sodium hydroxide and potassium hydroxide are often used in saponification reactions. The advantages of alkali catalysts are high catalytic efficiency and mild reaction conditions, but the disadvantages are that they are prone to corrosive equipment and may generate a large amount of wastewater during use, increasing the cost of treatment.
-
Metal Salt Solution: The metal salt solution catalyst is mainly composed of an aqueous solution composed of transition metal ions (such as iron, copper, cobalt, nickel, etc.) and anions such as halogen, nitrone, sulfur, etc. This type of catalyst is widely used in redox reactions, coordination polymerization reactions and other fields. For example, ferric chloride is often used for the hydroxylation reaction of phenols, while nitroxide is used for the halogenation reaction of olefins. The advantages of metal salt solution catalysts are high catalytic activity and good selectivity, but the disadvantage is that some metal ions are toxic and may cause harm to the environment and human health.
-
Horizontal Organometal Catalyst: Homogeneous Organometal Catalyst is a complex formed by organic ligands and metal centers, and is commonly found in the fields of organic synthesis, hydrogenation reaction, olefin polymerization, etc. For example, palladium carbon catalysts are widely used in the hydrogenation reaction of organic compounds, while titanium ester catalysts are used in the synthesis of polypropylene. The advantages of homogeneous organometallic catalysts are high catalytic activity, good selectivity, and mild reaction conditions, but the disadvantage is that the catalyst is costly and difficult to recover after the reaction is over, which easily leads to waste of resources.
2. Solid Catalyst
Solid catalysts are catalysts present in solid form, usually with a large specific surface area and pore structure, which can provide more active sites and thereby improve catalytic efficiency. Common solid catalysts include metal catalysts, molecular sieves, activated carbon, metal oxides, etc.
-
Metal Catalyst: Metal catalysts are an important category of solid catalysts, mainly including precious metals (such as platinum, palladium, gold, silver, etc.) and non-precious metals (such as iron, copper, nickel, cobalt, etc.) wait). Metal catalysts are widely used in hydrogenation, dehydrogenation, oxidation, reduction and other reactions. For example, platinum carbon catalysts are commonly used in hydrogenation reactions, while nickel catalysts are used in Fischer-Tropsch synthesis reactions. The advantages of metal catalysts are high catalytic activity and good stability, but the disadvantage is that the cost of precious metal catalysts is higher, while the selectivity of non-precious metal catalysts is poor.
-
Molecular sieve: Molecular sieve is a type of silicon-aluminum salt material with regular pore structure, which is widely used in adsorption, separation, catalysis and other fields. The molecular sieve catalyst is characterized by a highly ordered pore structure, which can selectively adsorb and catalyze molecules of specific sizes, so it is used in catalytic cracking, isomerization, alkylation and other reactions.��Express excellent performance. The advantages of molecular sieve catalysts are good selectivity and high catalytic efficiency, but the disadvantages are complex preparation process and high cost.
-
Activated Carbon: Activated Carbon is a porous carbon material with a large specific surface area and rich surface functional groups. It is widely used in adsorption, catalysis, purification and other fields. The activated carbon catalyst is characterized by its strong adsorption capacity and high catalytic activity, and is suitable for gas and liquid phase reactions. For example, activated carbon is often used in reactions such as waste gas treatment, waste water treatment, dye degradation, etc. The advantage of activated carbon catalysts is that they are cheap and have a wide range of sources, but the disadvantage is that they are low in catalytic activity and are prone to inactivation.
-
Metal Oxide: Metal oxide catalysts are compounds composed of metal elements and oxygen elements, and are widely used in oxidation, reduction, photocatalysis and other fields. Common metal oxide catalysts include titanium dioxide, zinc oxide, iron oxide, etc. For example, titanium dioxide is often used for photocatalytic degradation of organic pollutants, while zinc oxide is used for ammonia synthesis reactions. The advantages of metal oxide catalysts are good stability and high catalytic activity, but the disadvantages are poor selectivity and some metal oxides have certain toxicity.
3. Gas Catalyst
Gas catalysts are catalysts present in gaseous form and are usually used in gas phase reactions. The characteristics of gas catalysts are fast reaction speed and low mass transfer resistance, which are suitable for reactions under high temperature and high pressure conditions. Common gas catalysts include halogen gas, oxygen, nitrogen, etc.
-
Halogen gases: Halogen gases (such as chlorine, bromine, iodine, etc.) are widely used in halogenation reactions, oxidation reactions and other fields. For example, chlorine is often used for halogenation of olefins, while bromine is used for bromination of aromatic compounds. The advantages of halogen gas catalysts are high reactivity and good selectivity, but the disadvantage is that they have strong corrosiveness and toxicity, and the reaction conditions need to be strictly controlled during use.
-
Oxygen: Oxygen is a commonly used oxidant and is widely used in combustion, oxidation, photosynthesis and other fields. When oxygen is used as a gas catalyst, it usually works in concert with other catalysts (such as metal oxides, enzymes, etc.) to improve catalytic efficiency. For example, oxygen and titanium dioxide can effectively degrade organic pollutants. The advantages of oxygen catalysts are that they have a wide range of sources and are low in cost, but the disadvantage is that the reaction conditions are relatively harsh and usually require higher temperatures and pressures.
-
Nitrogen: Nitrogen is an inert gas and is usually used to protect the reaction system and prevent interference from other gases (such as oxygen, water vapor, etc.). Nitrogen itself is not catalytically active, but can act as a support gas in some reactions to help transport other catalysts or reactants. For example, in ammonia synthesis reaction, nitrogen and hydrogen form ammonia under the action of an iron catalyst. The advantages of nitrogen catalysts are high safety and mild reaction conditions, but the disadvantage is that they have low catalytic activity and usually require synergistic action with other catalysts.
Technical principles of low atomization and odorless catalyst
The reason why low-atomization and odorless catalysts can significantly reduce or eliminate atomization phenomena and odor problems while maintaining high-efficiency catalytic performance is mainly due to their unique technical principles and design ideas. Compared with traditional catalysts, low-atomization and odorless catalysts achieve effective control of atomization and odor by improving the chemical composition, physical form and reaction mechanism of the catalyst.
1. Chemical composition optimization
One of the core technologies of low atomization odorless catalysts is to optimize the chemical composition of the catalyst. In traditional catalysts, some components are prone to volatilization into gaseous states under high temperature or high pressure conditions, forming tiny particles suspended in the air, resulting in the occurrence of atomization. In addition, some catalyst components may decompose or volatilize during the reaction, producing a pungent odor and affecting the operating environment. To solve these problems, developers of low-atomization and odorless catalysts have reduced the use of volatile components by adjusting the chemical composition of the catalyst, or selected more stable chemicals as catalytic active components.
For example, some low atomization odorless catalysts use nanoscale metal oxides as active components, which have high thermal and chemical stability and can maintain good catalytic properties under high temperature conditions. Without volatilization or decomposition. Studies have shown that the specific surface area of nano-scale metal oxides is large and can provide more active sites, thereby improving catalytic efficiency. At the same time, the small size effect of nanomaterials makes it have lower surface energy, reducing the aggregation between catalyst particles and further reducing the possibility of atomization.
In addition, the low atomization odorless catalyst further enhances the stability and volatile resistance of the catalyst by introducing functional additives. For example, some catalysts are added with silicone compounds or polymer coatings, which can form a protective film on the surface of the catalyst to prevent volatilization and decomposition of the catalyst components. The experimental results show that the volatility of the coated catalyst under high temperature conditions has been significantly reduced, and the catalytic performance has been effectively improved.
2. Physical form innovation
In addition to chemical composition optimization, the physical morphology design of low-atomization and odorless catalysts is also one of its key technologies.. Traditional catalysts usually exist in powder or granular form. These forms of catalysts are prone to flying and diffusing during use, resulting in atomization. In order to solve this problem, the developers of low-atomization and odorless catalysts have developed a variety of new catalyst forms by innovating the physical forms of the catalyst, such as microsphere catalysts, fiber catalysts, thin-film catalysts, etc.
-
Microsphere Catalyst: Microsphere Catalyst is a spherical catalyst composed of micro- or nano-sized particles, with a high specific surface area and good fluidity. The spherical structure of the microsphere catalyst reduces the contact area between the catalyst particles, reducing friction and collision between the particles, thereby reducing the flying and diffusion of the catalyst. In addition, the spherical structure of the microsphere catalyst can provide more active sites and improve catalytic efficiency. Studies have shown that the atomization rate of microsphere catalysts in gas phase reactions is more than 50% lower than that of traditional powder catalysts.
-
Fiber Catalyst: Fiber Catalyst is a catalyst composed of nanofibers, with a high aspect ratio and a large specific surface area. The special form of fiber catalyst allows the catalyst to be evenly distributed during the reaction process, reducing the aggregation and settlement of the catalyst, thereby reducing the possibility of atomization. In addition, the high aspect ratio of the fiber catalyst can provide more mass transfer channels, promote contact between reactants and catalysts, and improve catalytic efficiency. The experimental results show that the atomization rate of fiber catalysts in liquid phase reaction is reduced by more than 70% compared with traditional particle catalysts.
-
Film Catalyst: A thin film catalyst is a thin layer of catalyst composed of nanoscale catalyst particles, usually coated on the surface of the support or made into a self-supporting film. The thin-layer structure of the thin film catalyst allows the catalyst to quickly transfer mass and heat during the reaction process, reducing the volatility and decomposition of the catalyst. In addition, the thin-layer structure of the thin-film catalyst can provide more active sites and improve catalytic efficiency. Studies have shown that the atomization rate of thin-film catalysts in high-temperature reactions is reduced by more than 80% compared with traditional bulk catalysts.
3. Reaction mechanism regulation
Another key technology of low atomization odorless catalyst is the regulation of the reaction mechanism. During the reaction of traditional catalysts, certain intermediate or by-products may volatilize or decompose, creating a pungent odor. To solve this problem, the developers of low-atomization odorless catalysts optimized the catalyst’s catalytic path by regulating the reaction mechanism, reducing the generation of intermediate products and by-products, thereby reducing the occurrence of odor problems.
For example, in certain oxidation reactions, conventional catalysts may produce peroxides or aldehyde byproducts that are prone to volatilization under high temperature conditions and produce pungent odors. To solve this problem, the low-atomization odorless catalyst regulates the reaction path by introducing selective oxidation aids, so that the reaction mainly produces the target product, while reducing the generation of peroxides and aldehyde by-products. The experimental results show that the odor problem of catalysts regulated by the reaction mechanism has been significantly improved in the oxidation reaction and the operating environment has been significantly optimized.
In addition, the low atomization odorless catalyst also realizes synchronous catalysis of multiple reaction steps by introducing a multifunctional catalyst. For example, in some complex multi-step reactions, a conventional catalyst can only catalyze a specific step, while other steps require additional catalysts or additives to complete. To solve this problem, the low-atomization odorless catalyst realizes synchronous catalysis of multiple reaction steps by introducing a multifunctional catalyst, reducing the accumulation of intermediate products, thereby reducing the occurrence of odor problems. Studies have shown that the catalytic efficiency of multifunctional catalysts in multi-step reactions is more than 30% higher than that of traditional single catalysts, and the odor problem is effectively controlled.
