Catalyst is the old name of catalyst used in chemical industry. When a substance has a chemical reaction, in many cases, adding a catalyst can speed up the reaction, so it is often used in dialects as a metaphor to promote the change of things.
Noun explanation:
A substance that can change the chemical reaction rate (increase or decrease) of reactants in a chemical reaction without changing the chemical equilibrium, and its quality and chemical properties have not changed before and after the chemical reaction is called a catalyst (solid catalyst is also called a catalyst). According to statistics, catalysts are used in more than 90% industrial processes, such as chemical, petrochemical, biochemical and environmental protection.
There are many kinds of catalysts, which can be divided into liquid catalysts and solid catalysts according to their state. According to the phase state of the reaction system, it can be divided into homogeneous catalyst and heterogeneous catalyst. Homogeneous catalysts include acids, bases, soluble transition metal compounds and peroxide catalysts. Catalysts play an extremely important role in modern chemical industry. For example, different catalysts are used in the production of three synthetic materials: iron catalyst for synthetic ammonia, vanadium catalyst for sulfuric acid, ethylene polymerization and rubber from butadiene.
