Abstract: This paper introduces the development of d esulfura-tion technology of FCC gasoline,including hydro-pretreat-ment of F CC materials,catalyst and cocatalyst desulfura-tion,isocracking process of FC C gasoline and absorptive desulfuration.It is pointed out that hydrodesufuriza tion and LADS are the promising technologies to solve the problems that sulfur contents are off standards while octane value is not enough.
