Advantages and disadvantages of chemical catalytic reaction

Catalytic reaction refers to adding catalyst in chemical reaction, which has the advantage of improving reaction rate and selectivity and efficiency of chemical reaction. Disadvantages are high cost and environmental pollution. The advantages and disadvantages of catalytic reaction are as follows.

1. Catalytic reaction can improve the reaction rate, shorten the reaction time and save energy and time.

2. Catalytic reaction can reduce reaction conditions, such as temperature and pressure, and reduce production costs.

3. Catalytic reaction can improve the selectivity of chemical reaction, avoid side reactions and improve the purity of products.

4. Catalytic reaction can promote the movement of reaction equilibrium, make chemical reaction reach equilibrium faster, and improve the yield of chemical reaction.

5. The cost of the catalyst itself is relatively high, which will increase the production cost.

6. The use of catalyst may produce waste and pollute the environment.

7. Deactivation and poisoning of catalyst will reduce the efficiency of catalytic reaction and the service life of catalyst.

8. The conditions of catalytic reaction are harsh, so it is necessary to choose suitable catalyst and reaction conditions, otherwise it may lead to catalyst deactivation or side reaction.
