Abstract:

This paper introduces the characteristics and principles of the alkylation of FCC gasoline desulfuriza-tion,and summarizes the technology status of alkylation des-ulfurization and research situations of desulfurization catalysts both at home and abroad in recent years. Alkylationdesul furization technology has the advantages of high desul-furization efficiency,reducing olefin content of oil and lowloss of octane number,low operation costs and low investment on equipments,which is suitable to make efforts to research on.
