Open publisher page 0 citations

Abstract

The requirement of sulfur content in gasoline becomes more and more stringent in response to growing environment pressures,and hydrodesulfurization is the most practical and effective way to decrease content of sulfur at present.In this paper,research progress in hydrodesulfurization process of FCC gasoline at home and abroad was introduced.Existing catalytic processes for HDS of FCC gasoline can be classified into two types: deep desulfurization-octane recovery with alkane isomerization(Oct-Gain and Isal) and selective HDS with preserving octane number(Prime-G+,SCANFining,CDHydro/CDHDS and OCT-M/OCT-MD,RSDS at home).
