Abstract
A process for the preparation of silver catalysts for the preparation of ethylene oxide, comprising: (a) impregnating a porous refractory support, having a surface area of from 0.03 m2/g to 10 m2/g, with a solution of an alkali metal compound having an atomic number of 19 to 55, in such a concentration that is obtained in the final catalyst, optionally after solvent extraction after step (b) or step (c), a content of from 0.25 to 16 milliequivalents-gram of the alkali metal per kilogram of total catalyst, for each square meter of surface area of the support per gram of catalyst support ((meq-g/kg)/(m2/g)); (b) drying at least partially the impregnated support of step (a); (c) contacting the product of step (b) with a liquid phase containing a dissolved silver compound, or a suspension of silver particles or a silver compound, to deposit 1 to 25 weight percent silver, relative to the total catalyst, on the surface of the support, and (d) heat treating the product of step (c) to convert the silver compound to mechanical silver.
