DEVELOPMENT AND APPLICATION OF DEEP HDS CATALYSTS FOR AROMATICS-RICH GASOLINE

Abstract

Abstract: To meet the demand of producing national standard Ⅴ and Ⅵ clean gasoline, Ni-Mo/Al2O3 catalysts with high HDS activities were prepared by introducing a certain proportion of chelating agents into the impregnating solution. Using aromatics-rich gasoline with high sulfur as a raw material, the performance of the catalysts were evaluated in a 100ml fixed-bed reactor at conditions of 245 ℃, 2.0 MPa, space velocity of 1.5 h-1 and H2/oil volume ratio of 300. The results show that the sulfur content is reduced from 740 μg/g to 5.0 μg/g, desulfurization rate reaches 99.4% with RON loss less than 1.0, indicating that the catalyst is suitable for processing aromatics–rich gasoline.

Key words: aromatics-rich gasoline, hydrodesulfurization, clean gasoline, catalyst
