The invention relates to a novel hydrogenation catalyst regeneration method in the technical field of the application of hydrogenation catalysts, in particular to a hydrogenation catalyst outside regeneration method in which conventional burning regeneration and chemical activation are combined and a technical quality standard. By using the regeneration method, the deposited carbon of the burnt deactivated spent catalysts can be effectively controlled; the intrinsic carbon is kept; the active metal aggregation degree is the minimum; the strength, the specific surface area and the pore volume are restored; and the foundation of chemical treatment is laid. Moreover, chemical activation (saturated dipping-drying) is carried out on the burning regenerant and the interaction between partial useful organic auxiliaries burnt in the burning process and the active metals is supplemented so that partial aggregated active metals are dispersed again and converted to a high-activity reactivity center in the vulcanization process and the activity of the catalyst is favorably restored.
