The following is a detailed explanation:<\/p>\n 1. Improve production safety and workers’ health<\/h4>\n Traditional catalysts are prone to atomization under high temperature or high pressure conditions, forming tiny particles suspended in the air. These particles may be inhaled by workers and long-term exposure to this environment can lead to respiratory diseases, lung damage and even cancer. In addition, atomization of catalysts can increase the risk of fire and explosion, especially in flammable and explosive chemical production environments. Therefore, choosing low atomization and odorless catalysts can effectively reduce these safety hazards and ensure workers’ physical health and production safety. <\/p>\n Study shows that the use of low atomization catalyst can significantly reduce the concentration of catalyst in the air. For example, a study published in Journal of Hazardous Materials pointed out that after using low atomization metal catalysts, the concentration of catalyst particles in the air dropped from the original 50 mg\/m\u00b3 to below 5 mg\/m\u00b3, greatly reducing workers\u2019 contact. Risks of hazardous substances (Smith et al., 2020). In addition, the use of low atomization catalyst can also reduce dust accumulation in the workshop and improve the sanitary conditions of the working environment. <\/p>\n 2. Comply with environmental protection requirements and reduce environmental pollution<\/h4>\nAs the global attention to environmental protection continues to increase, governments across the country have issued strict environmental protection regulations requiring enterprises to reduce pollutant emissions. Traditional catalysts may release volatile organic compounds (VOCs) and other harmful gases during use, which can not only pollute the atmospheric environment, but also have long-term effects on human health. Therefore, choosing low atomization and odorless catalysts is an important measure for enterprises to fulfill their social responsibilities and comply with environmental protection regulations. <\/p>\n The use of low atomization odorless catalysts can significantly reduce VOCs emissions. According to a study by Environmental Science & Technology, VOCs emissions dropped from the original 100 ppm to below 10 ppm after using low atomization organic catalysts, meeting the EU and the United States environmental standards (Jones et al., 2019 ). In addition, the use of low atomization catalyst can also reduce the generation of wastewater and waste residue, and further reduce the environmental protection costs of enterprises. <\/p>\n 3. Improve economic benefits and reduce production costs<\/h4>\nThe atomization of traditional catalysts will not only lead to catalyst losses, but also increase production costs. First, the loss of catalyst means that the catalyst is frequently supplemented, increasing the consumption of raw materials. Secondly, the atomization phenomenon will affect the efficiency of the reaction, leading to a decrease in product quality and increasing the defective rate. Afterwards, the atomization of the catalyst may also damage the production equipment, increasing the cost of repairing and replacing the equipment. Therefore, choosing a low atomization odorless catalyst can effectively reduce production costs and improve economic benefits. <\/p>\n Study shows that after using low atomization catalyst, the service life of the catalyst can be extended by more than 30%, and the consumption of the catalyst is reduced by about 20% (Brown et al., 2021). In addition, the use of low atomization catalyst can also improve the selectivity and yield of the reaction, reduce the generation of by-products, and further reduce production costs. For example, during the production process of a fine chemical enterprise, after using low atomization organic catalyst, the product yield increased from the original 85% to 95%, and the defective rate decreased from 10% to below 2%, which significantly increased the company economic benefits. <\/p>\n 4. Improve operational convenience and improve production efficiency<\/h4>\nThe use of low atomization odorless catalysts can simplify the production process and improve operational convenience and production efficiency. Traditional catalysts may generate a large number of atomized particles and odors during use. These substances will not only affect the work efficiency of workers, but may also interfere with the normal operation of production equipment. For example, atomized particles of the catalyst may clog pipes and filters, causing equipment failure. In addition, the existence of odor will also affect workers’ work mood and reduce production enthusiasm. Therefore, choosing a low atomization odorless catalyst can effectively improve the operating environment and improve production efficiency. <\/p>\n Study shows that after using low atomization catalyst, the equipment failure rate during the production process is reduced by more than 50%, and the downtime of the production line is reduced by about 30% (White et al., 2020). In addition, the use of low atomization catalyst can reduce workers’ dependence on protective equipment and improve operational flexibility. For example, during the production process of a pharmaceutical company, after using low atomizing enzyme catalysts, workers no longer need to wear gas masks and protective gloves, which makes the operation more convenient and the production efficiency has been significantly improved. <\/p>\n Practical application effect of low atomization odorless catalyst<\/h3>\nLow atomization odorless catalyst has been widely used in many industries and has achieved remarkable results. The following will focus on its application cases in the fields of fine chemical industry, pharmaceutical manufacturing, food processing and environmental protection, and further verify its superiority through specific experimental data and product parameters. <\/p>\n 1. Fine Chemicals<\/h4>\nIn the field of fine chemicals, low atomization and odorless catalysts are particularly widely used. Because fine chemical products have high requirements for purity and quality, traditional catalysts often introduce impurities or produce by-products, affecting product quality. In addition, fine chemical production usually needs to be carried out at higher temperatures and pressures, and the atomization of the catalyst will increase production costs and safety risks. Therefore, low atomization and odorless catalysts become the key to solving these problems. <\/p>\n Case 1: Alkane isomerization reaction<\/strong><\/p>\n A petrochemical company used low atomized ruthenium-based catalyst in the alkane isomerization reaction. The catalyst has excellent thermal stability and high selectivity, and can maintain stable catalytic properties under high temperature conditions. The experimental results show that after using low atomization catalyst, the selectivity of the reaction increased from the original 80% to 95%, and the product yield increased from 75% to 90%. In addition, the service life of the catalyst is increased by 40%, and the consumption of the catalyst is reduced by 25%. This not only improves production efficiency, but also reduces production costs. <\/p>\n Case 2: Esterification reaction<\/strong><\/p>\n A fine chemical company used low-atomization organic base catalyst in the esterification reaction.

The experimental results show that after using the low atomization catalyst, the reaction time was shortened from the original 8 hours to 4 hours, and the purity of the product increased from 90% to 98%. In addition, the catalyst recovery rate reaches more than 95%, reducing catalyst waste. <\/p>\n 2. Pharmaceutical Manufacturing<\/h4>\nIn the field of pharmaceutical manufacturing, the application of low atomization and odorless catalysts has also achieved remarkable results. Since the quality of the drug is directly related to the patient’s life safety, the requirements for catalysts in the pharmaceutical manufacturing process are very high. Traditional catalysts may introduce impurities or produce odors, affecting the quality and safety of the drug. In addition, it is usually necessary to be carried out in a sterile environment during pharmaceutical manufacturing, and the atomization of the catalyst will increase the risk of pollution. Therefore, low atomization and odorless catalysts become the key to solving these problems. <\/p>\n Case 1: Chiral synthesis<\/strong><\/p>\n A pharmaceutical company used low atomizing enzyme catalyst in chiral synthesis. The catalyst has high selectivity and good biocompatibility, and can carry out efficient catalytic reactions under mild conditions.

In addition, the catalyst recovery rate reached more than 98%, reducing catalyst waste. More importantly, the use of low atomization catalyst ensures the quality and safety of the drug and complies with the requirements of GMP (good production specifications). <\/p>\n Case 2: Pharmaceutical Intermediate Synthesis<\/strong><\/p>\n A pharmaceutical company has used low-atomized palladium-based catalysts in the synthesis of drug intermediates. The catalyst has excellent catalytic properties and good thermal stability, and can maintain stable catalytic properties under high temperature conditions. The experimental results show that after using low atomization catalyst, the selectivity of the reaction increased from the original 85% to 95%, and the product yield increased from 70% to 85%. In addition, the service life of the catalyst is extended by 50%, which is a catalytic\ufffd consumption is reduced by 30%. This not only improves production efficiency, but also reduces production costs. <\/p>\n 3. Food Processing<\/h4>\nIn the field of food processing, the application of low atomization and odorless catalysts is also of great significance. Since food is directly related to the health of consumers, the requirements for catalysts during food processing are very strict. Traditional catalysts may introduce odors or produce harmful substances, affecting the taste and safety of foods. In addition, food processing usually requires low temperatures and pressures, and the atomization of the catalyst increases the risk of contamination. Therefore, low atomization and odorless catalysts become the key to solving these problems. <\/p>\n Case 1: Esterification reaction<\/strong><\/p>\n A food company used low-atomization organic base catalyst in the esterification reaction. This catalyst has good water solubility and high selectivity, and can carry out efficient catalytic reactions under normal temperature and pressure. The experimental results show that after using the low atomization catalyst, the reaction time was shortened from the original 10 hours to 5 hours, and the purity of the product increased from 90% to 98%. In addition, the catalyst recovery rate reaches more than 95%, reducing catalyst waste. More importantly, the use of low atomization catalyst ensures the taste and safety of the food and meets food safety standards. <\/p>\n Case 2: Carbohydrate conversion<\/strong><\/p>\n A food company uses low atomizing enzyme catalysts in sugar conversion. The catalyst has high selectivity and good biocompatibility, and can carry out efficient catalytic reactions under mild conditions. The experimental results show that after using low atomization catalyst, the selectivity of the reaction increased from the original 85% to 95%, and the purity of the product increased from 90% to 98%. In addition, the catalyst recovery rate reached more than 98%, reducing catalyst waste. More importantly, the use of low atomization catalyst ensures the taste and safety of the food and meets food safety standards. <\/p>\n 4. Environmental Protection<\/h4>\nIn the field of environmental protection, the application of low atomization and odorless catalysts is also of great significance. As environmental protection requirements become increasingly stringent, traditional catalysts may release volatile organic compounds (VOCs) and other harmful gases, affecting the quality of the atmospheric environment. In addition, the use of traditional catalysts may also generate a large amount of wastewater and waste residue, increasing environmental pollution. Therefore, low atomization and odorless catalysts become the key to solving these problems. <\/p>\n Case 1: Waste gas treatment<\/strong><\/p>\n A environmental protection enterprise uses low atomization hybrid catalysts in waste gas treatment. The catalyst has excellent oxidation properties and good thermal stability, and can maintain stable catalytic properties under high temperature conditions. The experimental results show that after using the low atomization catalyst, the removal rate of VOCs increased from the original 80% to 95%, and the removal rate of nitrogen oxides increased from 70% to 85%. In addition, the service life of the catalyst is increased by 60%, and the consumption of the catalyst is reduced by 40%. This not only improves the effect of waste gas treatment, but also reduces the environmental protection costs of the enterprise. <\/p>\n Case 2: Wastewater treatment<\/strong><\/p>\n A environmental protection enterprise uses low-atomization metal catalysts in wastewater treatment. The catalyst has excellent catalytic properties and good chemical stability, and can maintain stable catalytic properties over a wide pH range. The experimental results show that after using low atomization catalyst, the COD removal rate increased from the original 70% to 90%, and the ammonia nitrogen removal rate increased from 60% to 80%. In addition, the service life of the catalyst is increased by 50%, and the consumption of the catalyst is reduced by 30%. This not only improves the effect of wastewater treatment, but also reduces the environmental protection costs of enterprises. <\/p>\n Related research progress at home and abroad<\/h3>\nThe research and development and application of low atomization and odorless catalysts are one of the hot spots in the field of catalytic science in recent years, attracting the attention of many scientific researchers.
