中海油惠州炼化为了满足全厂汽油升级至国Ⅳ、Ⅴ标准的要求，新建一套50万吨/年催化汽油加氢脱硫装置。该装置采用全馏分催化汽油选择性加氢脱硫技术（CDOS-FRCN），催化剂采用海顺德公司的催化剂专利技术。装置标定情况说明，催化汽油经全馏分加氢精制后，加氢精制汽油硫质量分数达到11μg/g，硫醇硫质量分数达到10μg/g，汽油辛烷值损失小于1.5个单位。二反入口温度对脱硫效果和辛烷值损失有很大影响，温度越高，则脱硫率越高，但辛烷值损失偏大。CDOS-FRCN技术能够有效降低汽油硫含量，减少辛烷值损失，可为炼油厂生产硫含量小于50μg/g甚至10μg/g的清洁汽油提供经济、灵活的技术方案。

50.0×104 t/a FCC gasoline hydrodesulfurization unit is a new-built unit for CNOOC Huizhou Refinery to meet the requirements of gasoline upgrading to national emissions standards No.4 and No.5. FCC full range gasoline selective hydrodesulfurization technology (CDOS-FRCN) is adopted in this unit,catalyst with proprietary technology is provided by Beijing Haishunde Titanium Catalyst Co. Ltd.. Unit calibration data show,FCC full range gasoline is converted to hydrogenated gasoline by CDOS-FRCN technology,the content of sulfur could reach 11μg/g,the content of mercaptan could reach 10μg/g,the loss of RON is less than 1.5. The inlet temperature of the second reactor R102 has a strong effect on the desulfurization effectiveness and RON loss,the higher R102 inlet temperature,the higher the desulfurization rate and the larger RON loss. CDOS-FRCN hydrodesulphurization technology could effectively decrease sulfur content in gasoline and octane number loss,could provide economical flexible technological options for producing clean gasoline with sulfur content less than 50μg/g or 10μg/g.
