The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is like the relationship between a lock and a key, and it has a high degree of selectivity. A catalyst does not catalyze all chemical reactions; some chemical reactions are not the only catalysts. So how much do you know about its catalytic reaction characteristics? China FCC/RFCC/DCC Catalyst editor will take you to a brief understanding.
1. Catalysts can only accelerate reactions that can be carried out thermodynamically. When a catalyst for a new chemical reaction is required to be developed, a thermodynamic analysis of the reaction is performed to see if it is a thermodynamically feasible reaction.
2. The catalyst can only accelerate the reaction to equilibrium, and cannot change the equilibrium position (equilibrium constant) of the reaction.
3. The catalyst is selective to the reaction. When the reaction may have more than one different direction, the catalyst only accelerates one of them, and the reaction rate and selectivity are unified.
4, the life of the catalyst. A catalyst can change the rate of a chemical reaction, and ideally the catalyst is not changed by the reaction. However, in the actual reaction process, some irreversible physical and chemical changes will also occur when the catalyst is heated and chemically acted for a long time.
The above is a brief introduction to the knowledge about the catalytic reaction characteristics of catalysts from China FCC/RFCC/DCC Catalyst editor.
