Abstract

The invention relates to an inferior oil hydrogenation catalyst carrier. According to a preparing method, modified natural bauxite is adopted, namely natural bauxite is roasted at high temperature in the air atmosphere and immersed in acid liquor for acid treatment to obtain the modified natural bauxite, by means of the treatment, aluminum oxide, silicon oxide and ferric oxide contained in the natural bauxite are purified, the crystallization degree is improved to form the catalyst carrier which contains aluminum, silicon and ferric and has certain cracking and hydrogenation performance, the acid activity centers of the treated natural bauxite are distributed again, and the specific area and the pore capacity are substantially increased. According to the bauxite modified and treated through the method, pore channel and pore diameter distribution in the structure are optimized, after the bauxite serves as the inferior oil hydrogenation catalyst carrier, the hydrogenation conversion performance of macromolecules such as asphaltene and colloid in inferior oil can be improved easily, and then the light distillate yield can be increased easily while the hydrogenation activity of the catalyst is improved.

Description
