摘　　要：主要进行了催化裂化轻汽油选择性加氢除二烯烃工艺条件优化研究,从反应温度、氢/油体积比和反应压力等3个方面考察了其对选择性加氢和3-甲基-1-丁烯异构为2-甲基-1-丁烯的异构化率的影响,确定选择性加氢的较优工艺条件为反应温度60℃、氢/油体积比30、反应压力1.5 MPa。在此基础上进行了选择性加氢催化剂1500 h寿命试验。试验数据表明,在1500 h的考察期内,催化剂表现出良好的活性稳定性。Studied the optimization of process conditions for diene removal of FCC light gasoline by selective hydrogenation. For the three factors of the reaction temperature, the hydrogen/oil volume ratio and the reaction pressure, investigated the influences on selective hydrogenation and isomerization rate from 3-methyl-1-butene to 2-methyl-1-butene.And determined that the reaction temperature was 60 ℃, the volume ratio of hydrogen and oil was 30 and the reaction pressure was 1.5 MPa were the optimum process conditions of selective hydrogenation. On this basis, a 1 500 hours life test of the selective hydrogenation catalyst was carried out, and the catalyst showed good activity stability.
