The invention discloses a preparation method of a supported hydrogenation catalyst. The preparation method comprises the following steps: 1, preparing a gamma-Al2O3 carrier; 2, dipping the gamma-Al2O3carrier in a solution of an active metal positioning and loading guiding agent, and drying the gamma-Al2O3 carrier; and 3, impregnating the gamma-Al2O3 carrier obtained in the step 2 with an impregnation liquid containing an active component, and carrying out drying and roasting to obtain the supported hydrogenation catalyst, wherein the active metal positioning and load guiding agent is one or more of a group consisting of ethylenediamine tetramethylene sodium phosphate, tetrabutylammonium fluoride and tartaric acid. The catalyst prepared by the invention can be used for hydrofining distillate oil such as gasoline distillate, kerosene distillate, diesel distillate and the like, and has high hydrodesulfurization and denitrification activity and aromatic hydrocarbon saturation activity. 本发明公开了一种负载型加氢催化剂的制备方法，该制备方法
