摘　　要：对比研究了3种沉淀剂对改性Y型分子筛的稀土利用率、中孔特性以及相应制备催化剂的微反活性和反应性能的影响。结果表明，稀土利用率大幅度提高，催化剂的反应性能得到一定改善，但是汽油性质有变差的趋势。The effect of several precipitators on rare earth utility of zeolite Y modification, medium porocity of modified Y and the MAT and reaction performance of as-prepared catalysts was investigated. The results showed that the rare earth utility increased greatly and the performance of catalysts was improved slightly. However, the properties of FCC naphtha became worse somehow.
