CDOS催化裂化汽油选择加氢脱硫技术的首次工业应用

First industrial application of CDOS FCC gasoline selective hydrodesulfurization technology

介绍了CDOS技术在中国石油华北石化分公司汽油加氢脱硫装置上开工情况及运行结果。工业应用标定结果表明,采用CDOS技术可将FCC汽油硫含量由541～600μg/g降至41～49μg/g,硫醇硫含量降至不大于10μg/g,辛烷值(RON)损失1.0～1.4个单位,CDOS技术可为炼油厂生产硫含量小于50μg/g的清洁汽油提供经济、灵活的技术方案。

The start operational situation and running results of CDOS technology applied to hydrodesulfurization unit of Huabei Petrochemical Co. CNPC are reviewed. The results of industrial application show that the sulfur content decreases from 541 - 600 μg/g to 41 - 49μg/g, the mercaptan sulfur content decreases to less than 10 μg/g, and RON loss is 1.0 - 1.4. CDOS technology is an economic and flexible process, which can applied to production of clean gasoline with sulfur content less than 50 μg/g for refinery.
