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。 This paper introduces the research and development of newly developed FCC catalyst L V23 with excellent vanadium resistance and industrial application results. The catalyst at a high conversion rate of low-grade mixed residue raw materials, can make liquefied petroleum gas, gasoline, diesel three high total yield. The dry gas and coke yield is very low under the premise of equilibrium vanadium mass fraction of 4 200 μg / g and nickel content of 6 100 μg / g. The performance of this catalyst is obviously superior to that of the imported counterparts.
