Abstract:
A process for removing alkynes, dienes, monounsaturated hydrocarbons and/or oxygen from streams of materials by hydrogenation, which comprises reacting the stream comprising alkynes, dienes, monounsaturated hydrocarbons and/or oxygen with hydrogen in the presence of a catalyst comprising, in its active composition, from 0.05 to 1.0% by weight of palladium or a palladium compound and from 0.05 to 1.0% by weight of silver or a silver compound, with the weight ratio of silver to palladium being from 0.95 to 1.05, and, as support, an SiO.sub.2 -containing catalyst support having a BET surface area of from 2 to 400 m.sup.2 /g, wherein at least 20% of the total pore volume of the catalyst is made up by pores having a diameter greater than 100 nanometers.
