摘　　要：催化裂化汽油是我国重要的车用汽油调合组分,提高催化裂化汽油辛烷值有重要意义。通过分析汽油中不同烃类的辛烷值的大小,结合催化裂化各反应机理,进一步查找出影响催化裂化汽油辛烷值的主要因素。某炼油厂以此为理论基础出发,结合其装置自身实际生产情况,从原料油、催化剂、操作参数进行了相应调整,最终使催化裂化汽油辛烷值得到明显的提高。FCC gasoline is the main blending component of vehicle gasoline in China.It is of great significance to improve the octane number of FCC gasoline.By analyzing the octane number of gasoline with different hydrocarbons and combined with the reaction mechanism of FCC,the main factors affecting the octane number of FCC gasoline were further found out.Based on this theory and combined with the actual production situation of the unit,a refinery adjusted the feed oil,catalyst and operating parameters accordingly,and finally significantly improved the octane value of FCC gasoline.
