Abstract
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.
Claims5
A silica-supported catalyst consisting essentially of 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, said catalyst being obtained by impregnating a silica support with a solution comprising at least one of said promoter metals, drying the impregnated support, impregnating with a palladium-including solution, drying and calcining.
A process for preparing a supported catalyst consisting essentially of 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, which comprises impregnating a silica support with a solution comprising at least one of said promoter metals, drying the impregnated support, impregnating with a palladium-including solution, drying and calcining.
