FO-35M催化剂再生及第2周期工业应用

Regeneration and Second Cycle Industrial Application of FO-35M Catalyst

随着环保法规的日趋严格,FCC汽油的脱硫、降烯烃、保持辛烷值已经成为我国清洁汽油生产的关键技术。由抚顺石化公司和中国石油石油化工研究院联合开发的FCC汽油加氢改质M-DSO技术,在第1周期平稳运行59个月,于2016年7月对催化剂进行再生补剂,开始第2周期运行。2017年9月国Ⅴ工况标定显示,在催化重汽油烯烃含量从42%(V/V)降至26%(V/V)以下,辛烷值未降低,回调全馏分汽油硫含量可降至10.0 mg/kg以下,完全满足该厂国Ⅴ汽油出厂调和的要求。

With the increasingly strict environmental regulations, FCC gasoline desulphurization, reducing olefins and maintaining octane number have become the key technologies for clean gasoline production in China. The FCC gasoline hydrogenation and modification technology M-DSO developed by Fushun Petrochemical Company and Chemical Research Institute of CNPC was steadily operated for 59 months in the first cycle. In July 2016, the catalyst was regenerated and began the second cycle application. In September 2017, the M-DSO technology was calibrated under National gradeV conditions. The results showed that the content of olefins in heavy FCC gasoline was reduced from 42%（V/V） to 26%（V/V）, the octane value was not reduced, and the sulfur content of gasoline in the total fractionation was less than 10.0 mg/kg,which could meet the gasoline blending requirements of National gradeV.
