摘　　要：为了满足国Ⅴ、国Ⅵ排放标准清洁汽油生产需求,开发了一种富芳烃汽油深度加氢脱硫催化剂。通过在金属浸渍液中引入一定比例的有机络合剂制备了高脱硫活性的Ni-Mo/Al_2O_3催化剂,催化剂微反评价结果表明,在反应温度245℃、反应压力2.0 MPa、体积空速1.5h^(-1)、氢油体积比300的条件下,可以将某石化公司富芳烃汽油的硫质量分数从740μg/g降至小于5.0μg/g,脱硫率达99.3%,辛烷值损失在1.0个单位以内,催化剂表现出较高的加氢脱硫活性,满足工业装置清洁汽油生产要求。To meet the demand of producing national standard Ⅴ and Ⅵ clean gasoline,Ni-Mo/Al2O3 catalysts with high HDS activities were prepared by introducing a certain proportion of chelating agents into the impregnating solution.Using aromatics-rich gasoline with high sulfur as a raw material,the performance of the catalysts were evaluated in a 100 mL fixed-bed reactor at conditions of 245℃,2.0MPa,LHSV of 1.5h-1 and H2/oil volume ratio of 300.The results show that the sulfur content is reduced from 740μg/g to 5.0μg/g,desulfurization rate reaches 99.4% with RON loss less than 1.0,indicating that the catalyst is suitable for processing aromatics-rich gasoline.
