Abstract:

Coated catalyst exhibits both the advantages of high strength of support and high reaction performance of catalytic coating,which has been widely concerned at home and abroad.Coating process plays a key role in the preparation process of coated catalysts,which has an important influence on the performance of the catalysts.Several common coated catalyst forming methods such as dip coating,spray coating and roll coating were summarized.The characteristics of catalyst support,forming additives and coating processes and the applications in catalytic reactions were introduced.On the basis of summarizing the important effects of coating process on catalyst forming effect,coating properties and product reaction performance,it was proposed that the coating process should be further optimized in the future to broaden the application scope of coating process.

Key words: coated catalyst, coating process, forming method, forming additive
