UOP's patent USP6,368,495 discloses an oxidation / decomposition combined desulfurization technology, which first oxidizes the sulfur-containing organic compounds in the oil to sulfones, and then catalytically decomposes the oxidized organic sulfur species into hydrocarbons and sulfur Compounds (such as SO2), but the decomposition of sulfone in this process needs to be carried out under higher temperature and pressure, which is not conducive to reducing operating costs, and the resulting oil cannot meet the requirements of ultra-low sulfur gasoline

Abstract
The process of preparing gasoline with very low sulfide content includes the following steps: mixing gasoline, catalyst Q+[MWxOy]- and hydrogen peroxide in the molar ratio of 1 to 80-100 to 600-800, and reaction at 60 deg.c to convert the other sulfide in the gasoline into SO2 and sulfone and obtain oxidized gasoline with sulfur content lower than 50 ppm; separating the catalyst from the oxidizedgasoline and recovering the catalyst; and washing the oxidized gasoline with water to eliminate sulfone and obtain oxidized gasoline with sulfur content lower than 50 ppm.
Description
A kind of preparation method of ultra-low sulfur gasoline technical field The invention relates to a preparation method of ultra-low sulfur gasoline. Background technique With the strengthening of people's awareness of environmental protection, the problem of automobile exhaust pollution has been paid more and more attention. Government organizations of various countries have enacted new environmental regulations one after another, stipulating new standards for various types of fuel oil, and strictly restricting the sulfur content, benzene content, aromatic hydrocarbon content, and olefin content. Especially the sulfur content. Taking gasoline as an example, the sulfur content standard implemented in the United States from the late 1980s was 1000ppm. In 1995, the sulfur content standard had dropped to less than 330ppm. In 2006, the sulfur content should be reduced to below 30ppm; It has dropped from 1000ppm in 1989 to less than 50ppm at present. Germany passed legislatio...
