摘要 |
Silver catalysts providing improved selectivities for the oxidation of ethylene to ethylene oxide are prepared by (a) subjecting a catalyst comprising from about 1 to about 35 percent by weight of silver on a porous refractory catalyst support to a stabilization treatment, and (b) depositing from about 0.00004 to about 0.008 gram equivalent weights per kilogram of total catalyst of ions of one or more of the alkali metals potassium, rubidium or cesium on the stabilized catalyst. |
