  • Silver-containing supported catalysts and catalyst intermediate products, processes for their preparation and their use
    Patent number: 4400308
    Abstract: Silver-containing supported catalyst, catalyst intermediates, processes for their preparation and the use of such catalysts in the preparation of alkaline oxides is described. By the preparatory technique of the invention there is obtained an improved catalyst which is especially useful in the preparation of alkylene oxides by oxidation of alkenes with oxygen-containing gases. The novel catalysts are characterized by a BET specific surface area of about 0.4 to about 0.5 square meters per gram and by a uniform continuous particle structure of spherical silver crystallites on a supported catalyst, which crystallites have an average diameter of 0.3 to 0.4 .mu.m.
