COMPOSITION ET PROCEDE POUR ELIMINER DES IMPURETES, NOTAMMENT LE POTASSIUM, DES CATALYSEURS USAGES D'ARGENT POUR LA PRODUCTION D'OXYDE D'ETHYLENE

摘要

A composition and method for removing alkali metal-containing impurities from supported silver catalysts wherein the composition is comprised of an inert organic liquid and a solubilizing agent. The method is used prior to regeneration of the catalyst with cesium, rubidium, or mixtures thereof to improve the selectivity of the regenerated catalyst.
