Silver catalysts, useful for the oxidation of ethylene to ethylene oxide, contain 3-20 percent by weight of silver and 0.003-0.05 percent by weight of potassium, rubidium, cesium, or a mixture thereof as a promoter present on a heat-resistant porous support to which they have been applied by several impregnating steps. |
