ABSTRACT:
A supported silver catalyst for oxidation of ethylene to ethylene oxide is prepared by impregnation of the support, activation, and solvent washing, with each step being carried out at a relatively low temperature. Silver so deposited has an average particle diameter of about 0.5-0.7 microns and is capable of being promoted by post-deposition of alkali metals such as cesium, rubidium, and potassium.
