A hydrogenation catalyst is obtained by pptn. of Ni from the solns. of its salts on a suspended silica gel under the influence of a precipitant. For decreasing the amt. of waste waters and for increasing the heat stability of the catalyst, aq. NH3 or (NH4)2CO3 soln. is used as a precipitant at 70-75° and pH 5-7.5. After cooling the catalyst is aged in mother liquor for 1.5-2 hr.
