摘　　要：针对国内某炼厂催化裂化汽油质量升级需要,对比了降低催化汽油烯烃含量和硫含量的工艺技术,最终选用了CDTECH公司的催化蒸馏技术,该技术包含CDHydro、CDEthers、CDHDS和ISOMPLUS工艺,通过轻汽油醚化,部分中汽油重整,重汽油选择性加氢脱硫,降低了催化汽油烯烃和硫含量,提高了辛烷值,满足了全厂生产国IV标准汽油要求。For the need of FCC gasoline quality upgrading in a refinery,some typical process schemes of decreasing the olefin and sulfur content were compared,and the catalytic distillation process of CDTECH company was chosen.The technology includes CDHydro,CDEthers,CDHDS and ISOMPLUS process.The FCC olefin and sulfur content can be decreased by light gasoline etherification,medium gasoline reforming and heavy gasoline selective desulphurization.The process can meet the requirements of States IV Regulation.

关 键 词：FCC汽油 脱硫 烯烃 辛烷值 升级
