摘要
ＦＣＣ 原料油中的镍、钒沉积在沸石催化剂上会导致严重的污染，使用钝化剂是解决镍、钒对沸石催化剂中毒的最经济有效的办法。本文综述了近２０ 年来，镍、钒对沸石催化剂的中毒及其钝化机理的研究进展。
FCC catalyst is polluted seriously by Ni and V deposited on it. Using metal passivators are the most economic and efficient method to solve this problem. In this paper, the study of mechanisms of pollution of Ni and V to FCC catalysts and their passivation in last two decades are reviewed.
