Abstract

The invention discloses a residual oil hydrogenation catalyst, comprising a carrier and an active metal component loaded on the carrier, wherein the carrier is a graphited reaming coal material; the specific surface area of the graphited reaming coal material is 200-960m<2> / g, the mean pore size is 10-100nm, the pore volume is 0.3-1.0cm<3> / g, the active metal component comprises one or more of VIII metallic oxides and VIB metal oxides, and the graphited reaming coal material is graphited reaming activated coal or graphited reaming semicoke. The invention also discloses a preparation method of the residual oil hydrogenation catalyst. Firstly, a carbon raw material is graphited and chambered to obtain the required carrier, and then the active component is soaked into the vector to obtain the residual oil hydrogenation catalyst.

Description

technical field [0001] The invention relates to a residual oil hydrogenation catalyst and its preparation method and application, belonging to the technical field of coal chemical industry. Background technique [0002] The world's oil resources are increasingly scarce, and the development of heavy and inferior crude oil makes the deep processing and upgrading technology of inferior residue / heavy oil more and more people's attention. Among them, the catalytic cracking process of residual oil is one of the most effective processes for lightening heavy oil, and the use of various hydrogenation catalysts is indispensable in the process of lightening residual oil. Common residual oil hydrogenation catalysts use alumina as the carrier and Mo / W and Ni / Co as the main active components. Patent CN102240555A discloses a residual oil hydrogenation catalyst with alumina as a carrier, the content of Ni / Co in the catalyst is 0.1-4wt%, the content of Mo / W is 1-5wt%, and the alumina carrie...
