A catalyst comprising, as an active ingredient, one of the following metals: copper, chromium, nickel, cobalt, manganese, zinc, and aluminum, is activated by the reduction of metals with an organic compound as a reducing agent. Such organic compounds as C8-C35 saturated hydrocarbons, C8-C19 unsaturated hydrocarbons, C8-C29 alicyclic hydrocarbons, C8-C10 aromatic hydrocarbons, C11-C13 aliphatic-aromatic hydrocarbons, C5-C30 monohydric alcohols, C2-C6 polyhydric alcohols, phenols, C7-C18 aliphatic aldehydes, C7-C18 aromatic aldehydes, C7-C35 aliphatic ketones, C6-C29 alicyclic ketones, C2-C31 aliphatic carboxylic acids, C2-C31 esters of aliphatic carboxylic acids, aromatic acids, carbohydrates, vegetable oils, animal fats, waxes, polyvinyl alcohols, polyvinyl acetate, polyethylene and polybutadiene, may be used as a reducing agent singly or mixed. The reducing agent is taken in an amount of 4 to 15 wt. %. per weight of the active ingredient of the catalyst. The process of reduction is carried out at a temperature ranging from 200 DEG to 800 DEG C.
