Supported Palladium Catalysts for Selective Catalytic Hydrogenation of Acetylene in Hydrocarbon Streams

摘要

The present invention can be obtained by impregnating a silica support with a solution containing at least one promoter metal, drying the impregnated support with a palladium containing solution, drying and calcining, and from 0.001 to based on supported catalysts. A silica supported catalyst suitable for the selective hydrogenation of acetylene in a hydrocarbon stream containing 1% by weight of palladium and 0.005 to 5% by weight of at least one Group 1 to 2 promoter metal of the periodic table.
