Study on vanadium-poisoning affecting catalysts in FCC and vanadium-traps and their applications

The mechanism of vanadium-poisoning in fluid catalytic cracking process is briefly introduced.In the course of damage caused by vanadium,the interactions between vanadium and some other elements are discussed.The application and developmentof vanadium-traps in some foreign countries are emphatically reviewed,and the research status of vanadium-traps in China is also analyzed.
