A selective hydrogenation catalyst comprises metallic copper activated by at least one of the metals Fe, Ni, Ru, Rh, Pd, Ir and Pt finely dispersed on a high surface area activated alumina and is prepared preferably by incorporating a cupric salt and a salt of at least one of the activating metals into an activated gamma- or kappa-alumina carrier by immersing the latter in a solution of the salts, converting the salts to their oxides and reducing to the metal. It is preferred to use copper of 99,9-99,999% purity.ALSO:Processes for the selective hydrogenation of acetylenes in the presence of di- and monoolefines, of acetylenes and diolefines in the presence of monoolefines, and of diolefines in presence of monoolefines, at elevated temperatures with hydrogen, are effected by use of a catalyst comprising metallic copper activated by at least one of Fe, Ni, Ru, Rh, Pd, Ir and Pt, finely dispersed on a high surface area activated alumina. Suitable feedstocks are 1:3-butadiene containing acetylenic or diolefinic hydrocarbons such as 1:2-butadiene; butylene containing at least one of 1:3-butadiene, vinylacetylene and ethylacetylene, and propylene containing propadiene or methylacetylene. |
