China Catalysts And Auxiliaries Suppliers

In chemical reactions reactants can change the chemical reaction rate (increase or decrease) without changing the chemical equilibrium, and its own quality and chemical properties of the chemical reaction did not change before and after the catalyst called (solid catalyst also called catalyst). According to statistics, about 90% of the industrial process using catalysts, such as chemical, petrochemical, biochemical, environmental protection and so on. [1] A wide range of catalysts, according to the state can be divided into liquid catalyst and solid catalyst; according to the reaction system is divided into homogeneous phase homogeneous catalyst and heterogeneous catalyst, homogeneous catalyst with acid, alkali, soluble transition metal compounds and peroxides catalyst. Catalysts occupy an extremely important position in the modern chemical industry. For example, three catalysts, namely, an iron catalyst for ammonia production, a vanadium catalyst for sulfuric acid production, ethylene polymerization, and three synthetic materials such as butadiene rubber are used .
