摘　　要：选用高硅铝比、小晶粒ZSM-5为活性组分和磷铝胶为基质,开发了具有提高汽油辛烷值同时控制液化气产率增幅和汽油收率损失的助剂LPC-A,并在华北石化公司1.2 Mt/a重油催化裂化装置进行了工业应用试验,取得了良好的应用效果:与空白阶段相比,助剂应用阶段的液化气产率平均增加了0.57个百分点,汽油RON升高了0.5个单位,同时丙烯产率增加了0.33个百分点,而总液体收率无减少。FCC additive LPC-A was then fabricated by using ZSM-5 with high silica-alumina ratio and small crystal size and aluminum phosphate.It showed excellent performance of enhancing gasoline research octane number(RON)and controlling increase of LPG yield and loss of gasoline yield simultaneously.In addition,LPC-A was successfully tested in RFCC unit with capacity of 1.2 Mt/a in Huabei petrochemical corporation.It showed that in the test period,average LPG yield increased by 0.57%and gasoline RON enhanced by 0.5 unit,while propylene yield increased by 0.33%and total liquid yield didn’t decrease,compared with the base result.
