Abstract:
A process for conditioning a high efficiency silver catalyst used to manufacture ethylene oxide from ethylene, oxygen, and at least one organic chloride is described. A non-reactive conditioning gas comprising at least one of ethylene, oxygen, and a ballast gas is introduced to the catalyst at a conditioning temperature ranging from 150° C. to 180° C. for a selected period of at least 4 hours.
