▎ 摘 要
NOVELTY - Hydrodesulfurization catalyst comprises a catalyst support comprising a zeolite doped with 0.1-0.5 wt.% of a graphene material, based on a total weight of the catalyst support, 5-20 wt.% of molybdenum, based on a total weight of the hydrodesulfurization catalyst and 1-6 wt.% of a promoter comprising cobalt and nickel, based on a total weight of the hydrodesulfurization catalyst, where the molybdenum and the promoter are homogeneously disposed on the catalyst support. USE - The hydrodesulfurization catalyst is useful for desulfurizing a hydrocarbon feedstock comprising a sulfur-containing compound (claimed). ADVANTAGE - The hydrodesulfurization catalyst: utilizes the Y-type zeolites that exhibits high thermal stability and high hydrothermal stability, hence stable; utilizes the graphene material that exhibits enhanced activity of the hydrodesulthrization catalyst by increasing e.g. the surface area, pore size, pore volume and hierarchy factor, hence effective and efficient; exhibits improved dispersion of the catalytic metals over the catalyst support, thus resulting in the efficient removal of sulfur from hydrocarbon feedstocks; and is free of metal carbides and metal nitrides. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) producing the hydrodesulfurization catalyst, comprising impregnating the catalyst support by adding an aqueous solution comprising a molybdenum salt and either a cobalt salt or a nickel salt to a suspension of the catalyst support in water to form a catalyst mixture, filtering the catalyst mixture to obtain a wet catalyst, and drying and calcining the wet catalyst thus producing the hydrodesulfurization catalyst; and (2) desulfurizing a hydrocarbon feedstock comprising a sulfur-containing compound, comprising contacting the hydrocarbon feedstock with the hydrodesulfurization catalyst in the presence of hydrogen gas to convert at least a portion of the sulfur-containing compound into a mixture of hydrogen sulfide and a desulfurized product, and removing the hydrogen sulfide from the mixture thus forming a desulfurized hydrocarbon stream.
