Catalysts for naphtha reforming

Claim 1

THE PROCESS OF REFORMING A NAPHTHA OF PRODUCE HYDROCARBONS BOILING IN THE GASOLINE BOILING RANGE HAVING SUPERIOR OCTANE NUMBERS WHICH COMPRISES SUBJECTING A NAPHTHA TO REFORMING AT AN ELEVATED TEMPERATURE IN THE PRESENCE OF A CATALYST COMPRISING ABOUT 7.0 TO 15.0 WEIGHT PERCENT OF MOLYBDENUM AND ABOUT 0.5 TO 1.5 WEIGHT PERCENT OF COPPER ON AN ACTIVATED ALUMINA CARRIER CONTAINING ABOUT 5 TO 15 WEIGHT PERCENT OF SILICA, SAID CATALYST BEING PREPARED BY CALCINING SAID ACTIVATED ALUMINA CARRIER AT A TEMPERATURE OF ABOUT 500 TO 600*C., IMPREGNATING THE CALCINED ACTIVATED ALUMINA WITH A DECOMPOSABLE MOLYBDENUM SALT IN AN AMOUNT EQUIVALENT TO ABOUT 7.0 TO 15.0 WEIGHT PERCENT OF MOLYBDENUM, DRYING THE IMPREGNATED ACTIVATED ALUMINA AT A TEMPERATURE OF ABOUT 110*C., IMPREGNATING THE DRIED ACTIVATED ALUMINA WITH A DECOMPOSABLE COPPER SALT IN AN AMOUNT EQUIVALENT TO ABOUT 0.5 TO 1.5 WEIGHT PERCENT OF COPPER, DRYING THE IMPREGNATED ACTIVATED ALUMINA, CALCINING THE ACTIVATED ALUMINA AT A TEMPERATURE OF ABOUT 500* TO 600* C. UNDER CONDITIONS WHEREBY THE MOLYBDENUM AND COPPER SALTS ARE CONVERTED TO METAL OXIDE FORMS AND SUBJECTING THE CALCINED MIXTURE TO HEATING IN AN ATMOSPHERE OF HYDROGEN AT 500*C. AND RECOVERING A REFORMED PRODUCT.
