摘要: Catalyst pellets with a high BET surface area can be formed from the compression of submicron powder into selected pellet shape, such as using press that forms in die. Catalysts particular interest comprise ceramic material an elemental metal coating. A low temperature plasma treatment used to achieve desired modification. are described have selectivities ethylene epoxidation reactions run over long time periods. The improved catalysts based upon catalyst materials, ytrria coated silver, selectivities. High areas achieved by particulate support material.
