Sulfurized hydrogenation catalyst and preparation method thereof

The invention provides a sulfurized hydrogenation catalyst and a preparation method thereof, and the preparation method comprises the following steps: (1) adding an extrusion aid into pseudo-boehmite, and mixing and kneading to obtain a system 1; (2) adding an auxiliary agent and water into the precursor of Co and/or Ni to obtain a solution A, then adding a complexing agent into the solution A, and mixing to obtain a solution C; adding an organic solvent into the precursor of Mo to obtain a solution B; (3) adding the solution C into the system 1, kneading, forming, drying and roasting to obtain a catalyst carrier D; and (4) impregnating the carrier D with the solution B, and carrying out drying and heat treatment to obtain the sulfurized hydrogenation catalyst. The method is easy to operate, the provided catalyst does not need to be pre-sulfurized before being used, active metal in a sulfurized state can be obtained by carrying out simple hydrogen introduction heat treatment at first during working, and a cla
