摘　　要：根据金属钒对FCC催化剂的中毒机理,研制出由碱土金属和稀土多组分复配而成的水溶性高效钝钒剂,并通过FCC固定床反应装置和轻油微反装置评价了钝钒剂的钝钒效果。结果表明,在催化裂化VEKT-60SL催化剂上钒含量为8 000μg/g时,LT-TV高效钝钒剂与单独使用稀土镧、铈制成的钝钒剂相比,它能更好地保护催化剂不受钒污染的影响,同时不影响催化裂化产品性质。Based on the mechanism of FCC catalyst deactivated by vanadium contamination, a high-activity and water-soluble liquid vanadium passivator（V-passivator）consisted of alkaline earth metal （A） and rare earth metal（R）was prepared. The effect of various V-passivators on the passivation performance of a commercial FCC catalyst,VEKT-60SL,contaminated with 8 000 μg/g vanadium was investigated using micro-activity test device and fixed-flui compared with single R-containing V-passivator, the vanadium passivation performance and without negative e zed bed reactor. The results indicated that as R-containing V-passivator exhibited better ect on product property.
