生产清洁汽油催化技术进展

Advances in catalytic techniques for production of clean gasoline

针对世界各国清洁汽油的发展趋势,叙述和分析了中国在生产清洁汽油方面的现状和各种生产清洁燃料的新技术,尤其是生产低硫、超低硫汽油技术。介绍了汽油中硫化物的来源和组成,分析了国内外汽油质量规格标准的进展,着重讨论了催化裂化(FCC)汽油脱硫技术及其经济性。

The restriction on sulfur level in gasoline has been increasingly tightened. Aiming at the present status of domestic gasoline quality, recently significant progress has been made in effective high sulfur removal, such as post treatment of FCC gasoline by selective hydrotreating. Source and composition of the sulfide in gasoline were introducted. Development in specifications for gasoline quality was analyzed. Post-treatment of FCC gasoline was emphasized.
