PROCESS FOR MAKING A SILVER CATALYST (D#75,605-1-F) ABSTRACT OF THE DISCLOSURE A highly-active catalyst is prepared by abrading or wearing away the surface of a silver catalyst whereby 1 to about 10 weight percent of the catalyst is removed. The initial silver catalyst is formed, for example, by impregnating a porous catalyst support with a solution of a silver salt, an aqueous solvent and a cesium or rubidium salt sufficient to deposit on the support an effective amount of the said alkali metal and subsequently heating the impregnated support at an elevated temperature to evaporate volatiles and activate the catalyst. -1-
