Method for preparing hydrogenation catalyst

The invention relates to a method for preparing a hydrogenation catalyst. The preparation method comprises the following steps of: dissolving salts of group VIB metals and group VIII metals in a hydrogen peroxide solution to obtain an impregnation liquid; impregnating the carrier by utilizing the impregnation liquid; and drying and roasting the impregnation product, thus obtaining the hydrogenation catalyst with double metal components. The method for preparing the load type hydrogenation refined catalyst has the advantages that the traditional impregnation method is improved, so that the interaction between active ingredients and the carrier is effectively weakened and the dispersion degree of the components on the carrier is improved. The hydrogen desulfurization and dearomatization activity of the catalyst prepared by the method is higher than that of the catalyst prepared by the traditional impregnation method and having the same active metal content.
