ABSTRACT:
A process for the preparation of ethylene glycol by the vapor phase catalytic hydrogenation of at least one of di(lower alkyl) oxalate and lower alkyl glycolate in the presence of a hydrogenation catalyst comprising a carrier, which catalyst is suitable for the hydrogenation of alkyl oxalate and alkyl glycolate to ethylene glycol, the improvement lies within the preparation of the catalyst by employment of catalysts comprising carriers having specific ranges of physical parameters, including average pore diameter and pore volume, which parameters are interrelated by a relative activity index.
