SUPPORTED BIMETALLIC ALLOYS ARE PREPARED BY COATING A SUPPORT WITH A HYDROGEN-REDUCIBLE SALT OF A FIRST METAL, E.G. COPPER, CONVERTING THE SALT COATING TO AN ELEMENTAL METAL COATING, AND SUBLIMING A SECOND METAL, E.G. ZINC, THEREON AT A TEMPERATURE SLIGHTLY ABOVE THE MELTING POINT OF THE RESULTANT ALLOY OF THE TWO METALS. THE METHOD IS ESPECIALLY SUITABLE FOR PREPARING HIGH SURFACE AREA, ALUMINA-SUPPORTED BRASS CATALYSTS, WHICH CATALYSTS ARE USEFUL FOR CATALYZING THE DEHYDROGENATION OF CARBINOLCONTAINING HYDROCARBONS. |
