METHOD FOR MAKING A HIGHLY SELECTIVE ETHYLENE OXIDE CATALYST |
摘要 |
A process for the preparation of a catalyst useful for the vapor phase production of ethylene oxide from ethylene and oxygen comprising providing a catalyst precursor comprising an inert support having 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 disposed thereon; calcining the catalyst precursor to convert the silver in the silver containing compound to metallic silver by heating the catalyst precursor to form a catalyst; and curing the catalyst in an inert gas atmosphere at temperatures of about 250° C. to about 600° C. for a period of about 1 hour to 200 hours. |
