摘　　要：介绍新开发的具有优良抗钒性能的渣油催化裂化催化剂 Ｌ Ｖ２３ 的研究开发情况及工业应用结果。该催化剂在高转化率下处理劣质掺渣油原料，可使液化气、汽油、柴油三者收率的总和较高。在平衡催化剂中钒的质量分数达到 ４ ２００ μｇ／ｇ、镍的质量分数达到 ６ １００ μｇ／ｇ 的前提下，干气和焦炭的产率很低，该催化剂性能明显优于同类进口对比催化剂。A newly developed FCC catalyst LV 23 for heavy oil cracking featured with high vanadium tolerance was put into use in a commercial resid FCCU. Dealing with inferior and refractory feedstock, high LPG plus gasoline plus LCO yield was obtained. At a condition of vanadium and nickel deposited equilibrium catalyst reached 4 200 μg/g and 6 100 μg/g respectively, the dry gas and coke yields were surprisingly low. The catalyst performance was remarkably better than that of the imported same type reference one.
