Abstract

The application discloses a hydrogenation catalyst, a preparation method and application thereof. The catalyst comprises a sulfided hydrogenation catalyst and a complex of auxiliary metals Fe and Mn, wherein the complex of auxiliary metals Fe and Mn contains two or more amine groups and / or imine groups. The preparation method of the hydrogenation catalyst comprises the following steps: (1) preparing a sulfided hydrogenation catalyst; (2) preparing an impregnation solution by mixing a Fe source and a Mn source with a complexing agent; and (3) impregnating the sulfided hydrogenation catalyst in step (1) with the impregnation solution in step (2), and drying to obtain the hydrogenation catalyst. The catalyst can realize reverse conversion of carbon deposition precursors to a certain extent, and is particularly suitable for a hydrogenation treatment process of secondary processing oil containing relatively high unsaturated hydrocarbons.
