中文摘要：在250万吨/年催化裂化装置上，通过逐渐调整操作参数，提出了工业生产装置降低催化裂化汽油烯烃含量的措施。提高催化剂活性、降低反应温度、降低原料预热温度、提高烃分压、提高二反区催化剂藏量、注入终止剂、提高剂油比、延长反应时间、提高汽油终馏点等，能有效降低催化裂化汽油烯烃含量8.1%（V/V），探讨了各种工艺参数对FCC 汽油烯烃含量的影响原因及机理。
英文摘要：In the 250 wt /a catalytic cracking unit, the measures for reducing the olefin content of FCC gasoline are proposed by gradually adjusting operation parameters. high the activity of the catalyst, low the reaction temperature,low feedstock preheating temperature, high the hydrocarbon partial pressure, high catalyst catalyst charge of the second reaction zone, injection of terminator, high the ratio of catalyst to oil, long reaction time, high gasoline end boiling point, can effectively reduce FCC gasoline olefin content of 8.1% (V/V). The reasons and mechanism of vairous process parameters on the olefin content in FCC gasoline were discussed.
