Abstract
Silver-based catalysts suitable for the production of ethylene oxide are prepared by impregnating a granular support with a decomposable silver salt, drying the impregnated products, and finally heat-treating the dried product at a high temperature, in a gaseous atmosphere containing at least 1 % by volume of carbon dioxide.
Claims19
A process for the preparation of silver-based catalysts suitable for the production of ethylene oxide, which comprises impregnating a granular support with a decomposable silver salt selected from the group consisting of the salts of lactic, citric, malic and isomalic acids, drying the impregnated products, and finally heat-treating the dried product at a high temperature, in a gaseous atmosphere containing at least 1% by volume of carbon dioxide.
