Coke Formation and Regeneration of FCC Catalyst: Effect of Vanadium Deposition and Vanadium Passivators

摘要

In FCC processing of heavy oils, metals (such as nickel, vanadium, iron) in feedstocks mostly on the surface of catalysts, lead to increasing coke formation and decreasing selectivity of products, so it is important to investigate the effect of vanadium deposition on the performance of FCC catalysts and develop new vanadium passivators.
