Abstract

Disclosed is a desulfurization catalyst for hydrocarbon oils, comprising a support and at least one metal promoter selected from the group consisting of cobalt, nickel, iron and manganese, the support comprising at least one metal oxide selected from the group consisting of oxides of Group IIB, Group VB and Group VIB metals and a refractory inorganic oxide, wherein the support further comprises at least about 5% by weight of vanadium carbide, based on the total weight of the desulfurization catalyst for hydrocarbon oils. The desulfurization catalyst for hydrocarbon oils shows a good stability, a high desulfurization activity, an excellent abrasion resistance, and a long service life. Also disclosed is a process for preparing the desulfurization catalyst for hydrocarbon oils, and use of the catalyst in the desulfurization of sulfur-containing hydrocarbon oils.
