Method for preparing an epoxidation catalyst |
| abstract |
A process for the preparation of a catalyst useful for the vapor phase production of ethylene oxide from ethylene and oxygen comprising the steps of 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; and heating the catalyst precursor in a gas atmosphere for a first period of time and a second period of time, wherein for the first period of time the gas atmosphere is an inert gas atmosphere and the temperature range is from about 25° C. to about 600° C., and then in a second period of time the gas atmosphere is an oxygen-containing atmosphere and the second period temperature range is from about 350° C. to about 600° C. |
