The invention discloses a preparation method of a sulfurized type hydrogenation catalyst. The method comprises the following steps: (1) preparing a solution containing a reactive metal complex, performing drying dehydration to obtain a reactive metal precursor, and preparing a semi-sulfurized material from the reactive metal precursor, a sulfurizing reagent and a sulfurizing aid by a mixed reaction; (2) uniformly mixing a peptizer, water and urea to obtain a liquid mixture; (3) adding an aluminum source to an acid aqueous solution, performing pulping, and then adding the semi-sulfurized material and the liquid mixture to the slurry; (4) performing rapid evaporation and concentration on the slurry to obtain concentrated slurry, and then performing slow drying treatment to obtain a semi-dried material; (5) performing rolling and extruding forming on the semi-dried material obtained in step (4), and performing roasting to obtain the sulfurized type hydrogenation catalyst. Catalyst preparation and sulfurization are finished simultaneously, pore size distribution of the catalyst is centralized, the preparation process is simple, and broader market application prospect is provided.
