Copper catalyst
Abstract
Abstract THE PRESENT INVENTION RELATES TO A PROCESS FOR THE PREPRATION OF A CATALYST MASS FROM DILUTE AQUEOUS SOLUTIONS OF COPPER AND NICKEL SALTS, PARTICULARLY PRECIPITATION OF A COPPER COMPOUND OUT OF AN AQUEOUS SOLUTION ONTO A THERMALLY STABLE CARRIER MATERIAL SUSPENDED THEREIN. THE COPPER COMPOUND IS SECURED TO THE CARRIER MATERIAL VIA A NICKEL COMPOUND AND IS REDUCED TO METALLIC COPPER AFTER BEING SO SECURED. COPPER CATALYSTS HAVE A WIDE FIELD OF APPLIATION IN DEHYDROGENATION REACTIONS, E.G., THE DEHYDROGENATION OF CYCLOHEXANOL TO CYCLOHEXANONE AND OF ISOPROPYL ALCOHOL TO ACETONE. COPPER CATALYSTS ARE ALSO VERY SUITABLE FOR CARRYING OUT SELECTIVE HYDROGENATION PROCESSES, THERE ARE INDICATIONS THAT METALLIC COPPER SURFACES MAY GREATLY ACCELERATE THE OXIDATION OF HYDROCARBONS E.G. CUMENE VIA RADICAL MECHANISMS.
