摘　　要：采用中国石化石油化工科学研究院开发的催化裂化汽油选择性加氢脱硫(RSDS-Ⅱ)技术,将某石化公司原有的一套0.3Mt/a喷气燃料加氢精制装置改造为0.2Mt/a催化裂化汽油选择性加氢装置,用不切割方案,氢气一次通过工艺,生产出可满足国Ⅳ汽油调合组分要求的精制汽油产品,精制汽油硫质量分数小于100gμ/g、硫醇硫质量分数小于20gμ/g,研究法辛烷值损失小于1个单位。Adopting FCC gasoline selective hydrodesulfurization（RSDS-Ⅱ） technology developed by Research Institute of Petroleum Processing,an existing 0.3 Mt/a jet fuel hydrofining unit was revamped to a 0.2 Mt/a gasoline hydrotreating unit.Using full-range FCC gasoline as feed and hydrogen once through process,the mass fractions of sulfur and mercaptan in the treated gasoline were less than 100 μ g/g and less than 20 μ g/g,respectively,which indicated that the blending product could meet the requirements of national emission standard Ⅳ for gasoline product,and the RON loss was less than 1 unit.
