催化剂及其助剂在催化裂化中的应用

The Application of Catalysts and Assistants in FCC

简述了催化裂化催化剂的发展历史阶段。针对近期发展动态,综述了催化裂化反应所用的各种催化剂及其助剂,其中包括提高液化气、汽油、柴油和烯烃收率的催化剂及其助剂,提高汽油辛烷值的催化剂及其助剂,如抗镍抗钒催化剂、助燃剂和硫转移剂。在比较各种催化剂性能相似点的基础上,对各种催化剂在催化裂化装置中应用的生产数据进行了描述。由于新型重油催化裂化催化剂的不断涌现,催化裂化催化剂的多功能化是催化裂化发展的必然趋势。

The developing history of catalysts of catalytic cracking was briefly presented. Based on its developing trends, all kinds of catalysts and assistants were reviewed, including catalysts or assistants of boost LPG, gasoline, diesel oil or alkene yield, catalysts or assistants of boost gasoline octane number, nickel passivator and vanadium passivator, combustion-supporting agent and sulfur transfer agent. According to some similar features of a great variety of catalysts and assistants, production data of catalysts of catalytic cracking were introduced. Because more and more heavy oil catalysts are exploited, multifunctional catalysts of catalytic cracking are also described. It is inevitable to produce multifunctional catalysts in the future.
