ABSTRACT:
A silver catalyst suitable for the oxidation of ethylene is provided in which the silver within a support particle, e.g., alumina, is non-uniformly distributed so that the silver concentration is clearly greater on the geometric surface and in the surface layer just beneath less than 0.5 mm thick than in the interior of the particles. The concentration of silver in the layer is two to a thousand times the concentration in the interior of the catalyst.
