摘　　要：针对催化裂化汽油烯烃含量较高的情况 ,在中型提升管催化裂化装置上 ,考察了原料油性质、催化剂性质、反应条件、汽油馏程等对汽油烯烃含量的影响 ,提出了工业生产装置降低催化裂化汽油烯烃含量的措施。研究发现 ,催化裂化汽油烯烃含量与氢转移指数 (异丁烷 /丁烯及异丁烷 /异丁烯 )呈线性关系 ,氢含量高、K值大的原料油 ,汽油烯烃含量较高。使用降烯烃催化剂、提高催化剂活性、提高剂油比、降低反应温度、延长反应时间、提高烃分压。The effects of operating parameters of FCC, such as the properties of feedstock, the characteristics of catalyst, the reaction condition and the gasoline boiling range, on the olefin content of gasoline were investigated on a 16kg/h pilot plant. The results showed that the olefin content of gasoline was in inverse proportion to the hydrogen transfer reaction index. The higher hydrogen content and higher K factor of the feedstock resulted in higher olefin content of gasoline. Low catalyst activity, high catalyst to oil ratio, low reaction temperature, long residence time, high oil partial pressure and higher gasoline end boiling point were in favor of decreasing the olefin content of gasoline.
