In a process for the hydrogenation of multiply unsaturated C.sub.2 -C.sub.8 hydrocarbons, in particular C.sub.2 -C.sub.8 -alkynes and/or C.sub.4 -C.sub.8 -alkynenes and/or C.sub.4 -C.sub.8 -alkadienes in fluids comprising these by contact with a catalyst packing in the presence of free hydrogen, the catalyst packing can be produced by applying at least one substance which is active as catalyst and/or promoter to woven or knitted meshes or foils as support material.

Hydrogenation process

A silica-supported catalyst suitable for the selective hydrogenation of acetylene in hydrocarbonaceous streams, comprising from 0.001 to 1% by weight, based on the supported catalyst, of palladium and from 0.005 to 5% by weight, based on the supported catalyst, of at least one promoter metal of groups 1 and 2 of the periodic table, obtainable by impregnating a silica support with a solution comprising at least one promoter metal, drying the impregnated support, impregnating with a palladium-including solution, drying and calcining.

Supported palladium catalyst for selective catalytic hydrogenation of

Water is removed from a mixture containing water, CO.sub.2 and one or more amines by pervaporation by bringing the mixture into contact with one side of a membrane and removing the water-containing permeate as a vapor from the other side of the membrane.
