A catalyst having monolithic structure for manufacturing ethylene glycol by oxalate hydrogenation, its preparation method and application are disclosed. The catalyst consists of honeycomb carrier, additive and active component, wherein the carrier is ceramic honeycomb or metal honeycomb; the additive is one or more oxides or metals selected from the group consisting of Al, Si, Ba, Ca, Ti, Zr, Fe, Zn, Mn, V, La, Ce, with the weight being 5-60% of the honeycomb carrier; the active component is Cu, with the weight being 1-25% of the honeycomb carrier; the active component Cu and additive are carried on the honeycomb carrier in a form of coating, with the total weight of coating being 10-60% of the honeycomb carrier and the weight of Cu being 10-40% of the total weight of coating. The catalyst has high activity and ethylene glycol selectivity, is environment friendly, pollution free, and suitable for large-scale industrial production. |
