Abstract
Abstract An improved process for hydrogenating organic compounds is provided in which a catalyst is employed that has a nickel surface area greater than about 70 m2/g and a sodium content less than 0.2 wt. percent based on the total weight of catalyst. Significantly improved activity is obtained with the nickelsilica catalyst of this invention particularly in conversion of benzene to cyclohexane, in reducing oxo aldehydes to alcohols, and hydrogenating olefin compounds to paraffins. The catalyst is prepared by coprecipitating nickel and silicate ions in the presence of a porous silica support under conditions of dilution that favor high surface areas and low inclusion of sodium in the catalyst.
