TITLE ETHYLENE OXIDE CATALYSIS INVENTOR CHARLES N. WINNICK ABSTRACT A supported silver catalyst, having particular utility in the production of ethylene oxide by the controlled, vapor phase, partial oxidation of ethylene employing molecular oxygen as the oxidant, is prepared by impregna- tion procedures. After impregnation, the catalyst is activated by thermal pyrolysis in an inert atmosphere and, subsequently, an alkali metal promoter, preferably a potassium, rubidium, and/or cesium salt is added to enhance catalyst performance. 1099
