采用高岭土原位晶化合成分子筛的方法，开发出一种加工重油的全白土 REHY 型催化裂化催化剂 LB-2，其分子筛含量约30%，孔径分布主要集中在3～10 nm。在钒、镍污染水平分别达到5 000 μg/g、3 000 μg/g 时，其活性、汽油产率及焦炭选择性优于国内外对比剂。工业应用结果表明， LB-2催化剂的液体收率高于原使用催化剂，其中汽油收率高约2个百分点，辛烷值也有明显改善，是一种性能优良的催化剂。

A novel REHY type FCC catalyst LB-2 for processing heavy oil was prepared from kaolin by in-situ crystallization, its molecular sieve content was around 30% and the pore diameters were mainly concentrated in the range of 300-1 000　nm. In comparison with the reference metal tolerance catalysts, the activity, naphtha yield and coke selectivity of LB-2 were better at vanadium and nickel depositions of 5 000 μg/g and 3 000 μg/g respectively. The commercial application showed that the liquid yield of LB-2 was higher than the original catalyst, the naphtha yield was 2% higher and the octane number was obviously improved.
