    Abstract: A CATALYSTIC COMPOSITE COMPRISING A COMBINATION OF CATALYTICALLY EFFECTIVE AMOUNTS OF A PLATINUM GROUP COMPONENT, A TIN COMPONENT AND A HALOGEN COMPONENT WITH A POROUS CARRIER MATERIAL IS DISCLOSED. THE PLATINUM GROUP, TIN AND HALOGEN COMPONENTS ARE PRESENT IN THE COMPOSITE IN AMOUNTS, CALCULATED ONAN ELEMENTAL BASIS, OF ABOUT 0.01 TO ABOUT 2 WT. PERCENT PLANTINUM GROUP METAL, ABOUT 0.01 TO ABOUT 5 WT. PERCENT TIN, AND ABOUT 0.1 TO ABOUT 3.5 WT. PERCENT HALOGEN. MOREOVER, THE TIN COMPONENT IS UNIFORMLY DISPERSED THROUGHOUT THE POROUS CARRIER MATERIAL IN A PARTICULE SIZE HAVING A MAXIMUM DEMENSION LESS THAN 100* A., AND SUBSTANTIALLY ALL OF THE PLATINUM GROUP COMPONENT IS PRESENT AS THE ELEMENTAL METAL AND SUBSTANTIALLY ALL OF THE TIN IS PRESENT IN AN OXIDATION STATE ABOVE THAT OF THE ELEMENTAL METAL. THE PRINCIPAL UTILITY OF THE SUBJECT COMPOSITE IS IN THE CONVERSION OF HYDROCARBONS, PARTICULARLY IN THE REFORMING OF A GASOLINE FRACTION. A SPECIFIC EXAMPLE OF THE CATALYST DISCLOSED IS A COMBINATION OF A PLATINUM GROUP METAL, TIN OXIDE AND HALOGEN WITH AN ALUMINA CARRIER MATERIAL WHEREIN THE TIN OXIDE COMPONENT IS UNIFORMLY DISPERSED THROUGHOUT THE ALUMINA CARRIER MATERIAL IN A RELATIVELY SMALL PARTICLE SIZE AND WHEREIN THE COMPOSITE CONTAINS ON AN ELEMENTAL BASIS 0.01 TO 2 WT. PERCENT PLATINUM METAL, 0.01 TO 5 WT. PERCENT TIN AND ABOUT 0.1 TO 3.5 WT. PERCENT HALOGEN.

    Abstract: THE EXHAUST GAS DISCHARGED FROM INTERNAL COMBUSTION ENGINES OR THE LIKE IS TREATED TO CONVERT HARMFUL OR NOXIOUS POLLUTANT COMPONENTS SUCH AS NITROGEN OXIDES, CARBON MONOXIDE AND UNBURNED HYDROCARBONS TO INNOCOUS COMPOUNDS, BY CONTACTING THE EXHAUST GAS WITH TWO STAGES IN SERIES OF A CATALYST COMPOSITION CONTAINING 5.0 TO 12.0% BY WEIGHT OF COPPER AS A EQUIVALENT COPPER OXIDE AND 0.5 TO 4.0% BY WEIGHT OF COBALT AS EQUIVALENT COBALT OXIDE, DEPOSITED ON PARTICLES OF ALPHA ALUMINA. THE CATALYST MAY ALSO CONTAIN A SMALL PORPROTION OF MANGANESE. AIR IS INJECTED INTO THE PARTIALLY REACTED EXHAUST GAS BETWEEN STAGES, SO THAT A REDUCTION OF NITROGEN OXIDES TAKES PLACE IN THE FIRST CATALYTIC STAGE OR BED, AND OXIDATION OF CARBON MONOXIDE AND HYDROCARBONS TO INNOCUOUS COMPOUNDS SUCH AS CARBON DIOXIDE AND WATER VAPOR TAKES PLACE IN THE SECOND CATALYTIC STAGE OR BED.

    Abstract: SUPPORTED RUTHENIUM CATALYSTS ARE MODERATED WITH AN ALKALI METAL HYDROXIDE OR ALKOXIDE BY MIXING THE SUPPORTED CATALYST AND THE ALKALI METAL COMPOUND IN THE REACTION MEDIUM OF A HYDROGENATION PROCESS WHICH MAY CONTAIN UP TO 5% OF WATER, AT A TEMPERATURE RANGING FROM ABOUT 30*C TO ABOUT 300*C. THE MODERATED CATALYST IS AN EFFECTIVE HYDROGENATION CATALYST FOR THE HYDROGENATION OF AROMATC AMINES TO THE CORRESPONDING SATURATED CYCLIC AMINES.
