The invention relates to the technical field of petrochemical engineering, particularly to a combined use method of a high-oxygen-content hydrocarbon hydrogenation catalyst. The method comprises the following steps: carrying out a pre-hydrogenation process on high-oxygen-content hydrocarbons through an inactive oxidation carrier catalyst bed layer, wherein the pre-hydrodeoxygenation uses an inactive oxide carrier catalyst; and carrying out a subsequent hydrogenation process on the pre-hydrogenation process product, wherein an active oxide carrier catalyst is adopted in the subsequent hydrogenation process. According to the invention, reaction materials are heated by utilizing reaction heat release in the pre-hydrogenation process, and the subsequent hydrogenation process is operated undera high-temperature condition, so that the adsorption capacity of the active oxide carrier to acidic raw materials is greatly reduced; and the fine deoxidation process is realized by utilizing the strong adsorption performance
