摘要： A catalyst is provided which is remarkably effective for catalyzing the oxidation of carbon monoxide to carbon dioxide at ambient conditions. This catalyst is prepared by contacting high surface area alumina with a solution of a cobalt compound (e.g., cobalt nitrate), adsorbing the cobalt compound on the alumina, removing the solvent, and thereafter heating the cobalt-treated alumina at a temperature of 400*C to 1,300*C in an oxygenproviding environment.

摘要： A membrane catalyst for carrying out simultaneous processes involving evolution and consumption of hydrogen, which membrane catalyst is in the form of a cellular foil made of an alloy of palladium and at least one other element selected from the elements in group VIII of the Periodic System other than palladium, gold, copper, or boron, the foil having oppositely directed alternate projections of hemispherical or halfellipsoidal shapes, the ratio of the projection height to the foil thickness being within the range from 10 to 200:1. If more than one foil membrane is used in the process, the foils are positioned parallel to one another so that the projections of one foil oppose the projections of the neighboring one. A gap must be provided between the foils to allow the passage of the starting material and the discharge of the reaction products.

摘要： Improved catalysts for oxidative dehydrogenation can be prepared by coprecipitating the metal containing catalysts from a solution of metal ions comprising iron and at least one other metal in the presence of a high molecular weight polyhydric material such as potato starch. The result of having the polyhydric material present is that the precipitate has the form of a gelatinous precipitate of improved processability. The catalyst itself is more active in dehydrogenations and physically stronger than comparable catalyst prepared by conventional methods.

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.
