| description | The invention provides a multi-component hydrogenation catalyst for synthesizing methyl glycolate, a preparation method and application of the multi-component hydrogenation catalyst in a reaction for synthesizing methyl glycolate through dimethyl oxalate hydrogenation, and belongs to the field of catalyst preparation. The specific process comprises the following steps: preparing catalyst precursor powder D, preparing catalyst powder G and preparing the catalyst. The catalyst prepared by the method is applied to a reaction for preparing a methyl glycolate catalyst through dimethyl oxalate hydrogenation, the catalyst has the advantages of high low-temperature activity, high methyl glycolate selectivity, good stability and the like, the abrasion is low, under the reaction condition of 185-210 DEG C, the dimethyl oxalate conversion rate is greater than or equal to 99%, the methyl glycolate selectivity is greater than or equal to 90%, and the methyl glycolate selectivity is greater than or equal to 90%.
