Abstract
An alumina support which contains cesium is prepared by adding a fusible compound of cesium to alumina along with known binders and porosity control agents. The cesium compound should be fusible below the temperature at which the alumina fuses. Such a support is especially useful as a support for a silver catalyst employed in the oxidation of ethylene to ethylene oxide.
