Abstract:
1. A process for the preparation of a catalyst useful for the vapor phase production of ethylene oxide from ethylene and oxygen which comprises impregnating an inert support with a solution comprising a catalytically effective amount of a silver containing compound, a promoting amount of an alkali metal containing compound, and a promoting amount of a transition metal containing compound; calcining the impregnated support by heating the impregnated support at a temperature of from about 200° C. to about 600° C. for a time sufficient to convert the silver in the silver containing compound to metallic silver and to decompose and remove substantially all organic materials; the heating being conducted under an atmosphere comprising a combination of an inert gas and from about 10 ppm to about 5% by volume of a gas of an oxygen containing oxidizing component.
