Abstract
Disclosed is a novel catalyst composition comprising a catalyst support material having deposited thereon elemental silver and a promoter selected from potassium, rubidium and cesium which are obtained by treating a catalyst precursor comprising a porous catalyst support material having deposited thereon a silver compound and a promoter selected from compounds of potassium, rubidium and cesium, with a gas comprising (i) hydrogen or (ii) an inert gas containing at least about 4 volume percent hydrogen at elevated temperatures. The disclosed catalysts are particularly useful in the partial oxidation of butadiene to produce 1,2-epoxy-3-butene.
