摘　　要：为了满足清洁汽油生产的需要,开发了一种催化裂化汽油预加氢催化剂。在氢分压为2.2 MPa,体积空速为3.0 h-1,氢油体积比为10∶1,反应温度为110℃条件下对催化剂进行了评价。结果表明,加氢产品的硫醇转化率为91.5%,二烯转化率为81.2%,加氢选择性为98.7%。评价结果显示开发的催化裂化汽油预加氢催化剂具有良好的硫醇、双烯加氢活性、选择性以及加工原料的适应性。A gasoline pre-hydrotreating catalyst is developed to meet clean fuel process.The mercaptans content in FCC gasoline is reduced by 91.5％.The diene value is lowered by 81.2％,and the hydrogenation selectivity is 98.7％under the folloing conditions：2.2 M Pa of reaction pressure,110℃ of temperature,3.0 h-1 of LHSV and 10 of H2/Oil volume ratio.It suggests that the pre-hydrotreating catalyst has high hydrogenation activity and selective hydrogenation activity to minimize the content of mercaptans and diene in FCC gasline.
