Study on MIP Technology for Production of EUROⅣClean Gasoline 1.Analysis of Rules for Transformation of Sulfur Compounds and Factors Influencing Sulfur Content in MIP Naphtha

<正>The rules of MIP reactions for catalytic cracking of sulfur compounds and its influence on the sulfur content in the MIP naphtha were studied.The mam factors influencing the sulfur content in the MIP naphtha were thought to be the sulfur content of feedstock and were closely related with the olefin content of naphtha.Taking into account the characteristic features of MIP process,the methods for reducing the sulfur content in the MIP naphtha were comprised of decreasing the sulfur content of feedstock by hydrotreating and decreasing the olefin content of naphtha through promoting hydrogen transfer reactions.Therefore,the EuroⅣclean gasoline with low sulfur content and low olefin content could be obtained directly through the MIP technology.
