The invention relates to a method for preparing a loaded hydrofining catalyst. The method comprises the following steps of: dissolving metal salts into an aqueous hydrogen peroxide solution so as to obtain impregnation liquid; carrying out impregnation on a carrier by using the impregnation liquid; and drying and roasting an impregnation product so as to obtain the loaded hydrofining catalyst. The catalyst prepared by using the method disclosed by the invention is higher in active component dispersity and poor in interaction of active components and carriers, and has better hydrodesulfurization activity and hydro-dearomatization activity in comparison with a catalyst prepared by using the conventional impregnation method.
