The catalyst of RFG-DQ and DOCO(1) can both reduce the olefine content of gasoline dramatically, with the yield of LPG ,diesel and coke reduced and the yield of gasoline increased, as well as octane number of gasoline reduced more greatly.The olefine content of gasoline can be effectively reduced by optimizing the operation condition, lowering the reaction temperature, increasing the catalyst-to-oil ratio and using catalyst, which can improve the gasolines quantity and upgrade the gasoline.

Study result suggest: The change of stock in RFCCU directly affect gasoline content. Gasoline content can be reduced through increasing the equilibrium activity of catalyst, controlling reaction level, increasing recirculating rate of gasoline and stability of gasoline level. Conclusions drawn from experiment is that optimization of operating condition has great effect on lowering olefine content of gasoline which can be reduced from 60% to 50%.Reducing reaction temperature is useful for lowering olefine content of gasoline, when the reaction temperature is raised, thermal cracking rate is higher than catalytic cracking rate, so that olefine content is increased. Raising catalyst-to-oil ratio is good for lowering olefine content. With conversion rate increased, the yield of LPG and coke is raised, the yield of gasoline is increased firstly and then decreased slightly, hydrogen transfer index is increased, so the olefine content is decreased.

研究结果表明：催化裂化装置的原料的变化直接影响到催化汽油的烯烃含量；可以通过优化催化装置的操作条件来降低催化汽油中的烯烃含量，其中通过提高催化剂平衡活性、控制反应深度、增加汽油回炼量、汽油深度稳定可以降低催化汽油烯烃含量，优化工艺条件对降低催化汽油烯烃含量有较大作用，汽油烯烃含量由60％降至50％左右；降低反应温度有利于降低催化汽油的烯烃含量，当反应温度的提高，热裂化反应速度提高的幅度大于催化裂化反应速度提高的幅度，汽油烯烃含量增加；剂油比的提高有利于降低催化汽油的烯烃含量，转化率提高，液化气产率提高，汽油收率先增加后略有下降，焦炭产率增加，氢转移反应指数提高，汽油烯烃含量下降；反应时间对产品分布及汽油烯烃含量有影响，增加提升管反应时间，液化汽、汽油产率提高，干气和焦炭产率增加。
