Molecular recognition and adsorption performance of benzothiophene imprinted polymer on silica gel surface

With the gradually strictly of the environmental disciplines,the requirement for the quality of gasoline is getting higher.The method of reducing gasoline sulfur is considered to be an effective means for improving air quality.The desulfurization technology has become a key technology in various oil refinery enterprises.Sulfur compounds in gasoline come mainly from FCC(Fluid Catalytic Cracking),researching and developing of FCC gasoline desulfurization technology is very important.At present,technologies of reducing sulfur content of FCC gasoline including catalytic cracking desulfurization,FCC gasoline hydrodesulfurization,biodesulfurization,solvent extraction desulfurization,plasm and photochemical desulfurization,adsorption desulfurization and oxidative desulfurization.FCC gasoline desulfurization technologies at home and abroad were reviewed in this paper.
