Process for preparing epoxidation catalyst |
abstract |
Providing a catalyst precursor comprising a catalytically effective amount of a silver-containing compound, a promoted amount of an alkali metal-containing compound, and an inert support comprising a promoted amount of a transition metal-containing compound disposed thereon; And heating the catalyst precursor in a gas atmosphere for a first period and a second period, wherein during the first period the gas atmosphere is an inert gas atmosphere and the temperature range is from about 25 ° C. to about 600 ° C. Wherein the gas atmosphere is an oxygen-containing atmosphere for two periods and the temperature range of the second period is from about 350 ° C. to about 600 ° C. |
