In order to upgrade the products quali-ties,the KF 767-1.3 Q,KF 860-1.3 Q and Neb-ula 20 catalysts,manufactured by Albemarle Corpo-ration,were adopted in an 800 kt/a catalytic diesel oil,coker diesel and coker gasoline hydrogenation unit for producing the refined diesel meeting the re-quirement of national standard Ⅳ,Ⅴ requirements. The operation results showed that under the condi-tions of processing capacity 80 t/h,feeding tempera-ture 265℃,inlet pressure 7.66 MPa,total tempera-ture rise 103℃,inlet hydrogen flow rate 15 000 m3/h,sulfur content of refined diesel was lower than 40 μg/g,reaching the requirement of national stand-ard Ⅳ;after increasing the inlet temperature from 265℃ to 270 ℃,under the conditions of hydrogen partial pressure 6.95 MPa,volume velocity 1.9 h-1, sulfur content of refined diesel was 1.8-4.5 μg/g, reaching the requirement of national standard Ⅴre-quirements.%为了升级产品质量,中国石油独山子石化公司80万t/a催焦化汽柴油加氢装置采用美国雅保公司生产的KF 767-1.3 Q,KF 860-1.3 Q 和Nebula 20催化剂,生产满足国Ⅳ、国Ⅴ要求的精制柴油.运行结果表明:在加工量为80 t/h,反应进料温度265℃,反应入口压力7.66 MPa,总温升103℃,新氢流量达到15000 m3/h的条件下,精制柴油含硫量低于40 μg/g,可达到国Ⅳ要求.将装置反应入口温度从265℃提高至270℃,在反应器入口氢分压6.95 MPa,体积空速1.9 h-1的条件下,精制柴油含硫量为1.8~4.5 μg/g,可满足国Ⅴ柴油标准.
