摘要
在汽油加氢过程中,原料中存在的烯烃和加氢脱硫生成的硫化氢会发生反应生成硫醇和其他硫化物等二次硫化物,使加氢脱硫后油品中硫醇硫及总硫含量升高,这对生产清洁汽油是一个严重的障碍。综述了汽油加氢精制过程中生成二次硫化物的国内外研究进展,并对研究该反应的重要性及未来趋势进行了展望。
In the process for gasoline hydrodesulfurization, the reaction between olefin in the feedstock and hydrogen sulfide formed by hydrogensulfurization will occur and mercaptans and other sulfides are produced, so the content of the mercaptan and total sulfide in the gasoline product after the hydrodesulfufization process is higher, which is a serious obstacle for producing clean gasoline. In this paper, the development of the formation of mercaptans and other sulfides by reaction between olefin and hydrogen sulfide in hydrofining progress of gasllne is summarized, and the importance and future trend for the reaction between olefin and hydrogen sulfide are put forward as a prospect.
