    摘要: Ethanol is prepared by contacting ethylene and liquid water or an aqueous solution of an inert solvent with a catalytic amount of a prereduced catalyst consisting of a blue tungsten oxide on a zirconia support at 250*-350* C., 750-5,000 psi, and a mole ratio of water to ethylene of 5:1 to 25:1.

    摘要: 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. % based on the total weight of catalyst. Significantly improved activity is obtained with the nickelsililca catalyst of this invention particularly in conversion of benzene to cyclohexane and in reducing oxo aldehydes to alcohols. 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.
