Abstract
A porous inorganic oxide support comprising an oxygen-containing carbonaceous material supported thereon, preferably a porous inorganic oxide support wherein the oxygen-containing carbonaceous material is a carbide of an oxygen-containing organic compound, wherein the ratio of the supported carbon amount with respect to the mass of the support for preparing the catalyst is from 0.05 to 0.2, the atomic ratio of the supported hydrogen amount with respect to the supported carbon amount is from 0.4 to 1.0, and the atomic ratio of the supported oxygen amount with respect to the supported carbon amount is from 0.1 to 0.6; and a hydrotreating catalyst of catalytic cracking gasoline which comprises the support and a catalyst containing a Group 8 metal of the periodic table, molybdenum (Mo), phosphorus and sulfur which is supported on the support are useful as a desulfurization catalyst of, for example, catalytic cracking gasoline at a hyperdesulfurized level, because of having functions of suppressing the hydrogenation activity of olefins and minimizing the decrease in the octane number even under reaction conditions with a high desulfurization ratio.
