摘　　要：介绍了中国石化武汉分公司催化裂化柴油(LCO)的加工路线,对LCO进柴油加氢装置精制、进加氢裂化装置掺炼、与蜡油加氢混炼及LTAG工艺进行对比。结果表明:LCO进柴油加氢装置精制仅能实现柴油的脱硫精制,进加氢裂化装置掺炼有利于化工料的增产及柴油十六烷值的提升;LTAG工艺增产汽油的效果好于LCO与蜡油加氢混炼工艺,也是经济效益最优的工艺路线,但加氢深度要求较高。因此,优化加氢效果,投用LTAG工艺是武汉分公司催化裂化柴油加工首选的经济性途径。The comparisons of the processing results of LCO hydrofining, hydrocracking of VGO mixed with LCO,hydrotreating VGO mixed with LCO and LTAG in SINOPEC Wuhan Company were introduced. The results show that LCO hydrofining can only achieve desulfurization,and the hydrocrac- king of VGO blended with LCO is favorable for the production of petrochemicals and the improvement of diesel cetane number,while LTAG process can produce much more gasoline than that of the hydrotreating VGO mixed with LCO process and is the most economical processing route, but needs severer hydrotreating operation. It is recognized that the LTAG process combined with optimal LCO hydrotreating process is the primary economical choice for LCO processing in Wuhan Company.
