CATALYST COMPOSITION FOR SELECTIVE HYDROGENATION WITH IMPROVED CHARACTERISTICS

摘要

2This invention relates to heterogeneous catalysts useful for selective hydrogenation of unsaturated hydrocarbons comprising palladium and optionally a promoter supported on a substrate having an uncoated BET surface area of < 9 m/g the surface being coated with an ionic liquid. Also described are methods of making the catalysts and methods of selective hydrogenation of acetylene in front end mixed olefin feed streams.
