In the process of manufacturing ethylene glycol from coal, the catalyst used in the hydrogenation of oxalic acid needs to be replaced frequently, which seriously affects the routine operation of the system. Based on the analysis of the causes of the inactivation of the catalyst during the hydrogenation of oxalic ester,  we took effective measures to overcome this problem, good results have been obtained.
