Ethylene glycol and propylene glycol may be made by hydrogenolysis of a polyol comprising the steps of reacting a polyol with hydrogen in the presence of a hydrogenolysis catalyst. The hydrogenolysis comprises nickel, one or more promoter, and one or more support. The promoter is selected from bismuth, silver, tin, antimony, gold, lead, thallium, cerium, lanthanum, and manganese. The support is selected from zirconia and carbon. A zirconia support comprises a zirconia textual promoter, which is selected from Cr, Mo, W, Nb, Ce, Ca, Mg, La, Pr, Nd, Al, and P. If the support comprises carbon, then the promoter is selected from bismuth and antimony. In another embodiment, if the support comprises carbon, then both the promoter is selected from bismuth and antimony, and the catalyst comprises copper. In another embodiment, the catalyst additionally comprises copper.
