摘要

For the synthesis of Ethylene Glycol (EG) from syngas using the Dimethyl Oxalate (DMO) route, an important steprnis the hydrogenation of DMO. Cu/SiO_2 based catalysts have the advantage of high selectivity toward EG and thernintermediate Methyl Glycolate (MG), but the conventional methods used for catalyst’s synthesis were hard to scaleuprnfor industrial use. A quicker, safer (compared to ammonia evaporation) method of copper deposition wasrndeveloped using ammonium carbonate as a precipitation agent. The results of various techniques for the preparationrnof Cu/SiO_2 are compared in term of catalytic activity, materials properties and ease of scale up.
