摘要
中国石化金陵分公司250万t／a柴油加氢装置，以第Ⅲ和第Ⅳ套常减压装置生产的柴油和第Ⅱ套催化裂化装置生产的催化柴油为原料（后者质量分数约为10％），其中含硫质量分数约为1％，采用FHUDS-5／FHUDS-6催化剂组合工艺技术，在精制反应器入口温度为320—330℃，反应压力为7，2MPa的条件下，可生产清洁柴油。结果表明，FHUDS-6催化剂活性强，装填在反应器上床层，有利于多环芳烃的饱和；FHUDS-5催化剂装于下床层，有利于脱除大分子硫化物。精制柴油产品的质量得到改善，密度较原料平均降低23．0～25．0kg／m^2，十六烷值均高于50，满足欧V标准要求。
FHUDS- 5/FHUDS- 6 combination catalysts were applied to the 2.5Mt/a diesel hydrotreating unit of Jin- ling Petrochemical Company, SINOPEC,with atmospheric and vacuum diesel from unit Ⅲ and IV and catalytic cracking diesel （ mass fraction about 10% ） from FCC unit II as raw materials （sulfur- bearing mass fraction around 1% ）at inlet tempera- ture of reactor 320 - 330 ~C , reaction pressure 7.2 MPa. The results showed that FHUDS -6 catalyst with higher activitywas packed in the upper bed layer to saturate the polycyclic aromatics,and FHUDS -5 catalyst was packed in the lower bed layer to remove macromolecules sulfide. The quality of diesel product was improved including that the density was re- duced by 23.0 -25.0 kg/m3 averagely and the cetane value was more than 50,which meet the Europe V standard.
