摘　　要：将裂解C5馏分资源经选择性加氢、醚化,合成了高辛烷值汽油调和组分。为满足醚化催化剂的要求,进行了蒸汽裂解C5双烯烃选择性加氢工艺研究,对裂解C5双烯烃选择性加氢催化剂进行了评价,考察了反应压力、空速、反应温度、氢烯摩尔比对双烯烃选择性加氢的影响,得出适宜工艺条件为:反应压力0.5～1.5 MPa,温度45～80℃,空速10～2．0 h-1 ,氢烯摩尔比大于1.1。Etherification of the C5 cut from steam cracking for the synthesis of high octane number composite of gasoline after selective hydrogenation is a high profit process with low investment. In order to meet the requirement of the catalyst for etherification, di olefin selective hydrogenation of the C5 cut from steam cracking was studied. After evaluating the catalyst, process parameters such as reaction pressure, LHSV, temperature and H/oil molar ratio on the di olefin selective hydrogenation were optimized and the following optimal values were obtained： 0.5 - 1.5 MPa, 45 -80 ℃, LHSV = 1.0 -2, 0 h^-1 and H/oil molar ratio 〉 1.1.
