车用燃料脱硫技术进展

Advances in the Desulfurizaton of Gasoline and Diesel

介绍了国内外利用优化催化裂化操作条件、氢转移反应、选择性加氢、生物催化脱硫、吸附脱硫等脱硫技术降低汽油、柴油硫含量的发展状况 .分析认为对于低硫原油产品利用氢转移活性高的催化剂、对于含硫原油产品利用高选择性的生物催化脱硫和加氢脱硫的组合完全可以达到车用燃料深度脱硫的要求 .

In order to protect environment, the sulfur content of automobile fuel is required lower and lower. Some domestic and foreign desulfurization techniques are introduced. The author holds that, in order to reduce sulfur content, hydrogen transfer reaction can be used in FCC of low sulfur crude oil, and high selective biocatalytic desulfurization and hydrodesulfurization can be used for high sulfur crude oil.
