Process for preparing a ruthenium promoted, halogen-containing, nickel and/or cobalt catalyst includes impregnating, in one or more steps, a porous metal oxide support with a nickel compound and/or a cobalt compound, and a ruthenium compound to form a catalyst intermediate; reducing the nickel compound and/or cobalt compound, and ruthenium compound, in one or more steps, to the respective metal by reacting the catalyst intermediate with hydrogen gas at an elevated temperature sufficient to reduce the respective compounds to the metal; and introducing halogen by adding a halide compound at any stage in the process. Catalyst prepared by the above process and use thereof.

A process for the preparation of a ruthenium-promoted, halogen-containing, nickel and/or cobalt catalyst, which catalyst contains, based on the total weight of the catalyst, from 4-40% by weight of at least one metal selected from nickel and cobalt, from 0.1-5% by weight of ruthenium and a porous me

A process for the preparation of a ruthenium-promoted, halogen-containing, nickel and/or cobalt catalyst, which catalyst contains, based on the total weight of the catalyst, from 4-40% by weight of at least one metal selected from nickel and cobalt, from 0.1-5% by weight of ruthenium and a porous metal oxide support, the process comprising: impregnating, in one or more steps, a porous metal oxide support with a solution or slurry of at least one metallic compound selected from a nickel compound and a cobalt compound; and a solution or slurry of ruthenium compound, the porous metal oxide support being comprised of at least 50% by weight of a material selected from activated alumina and activated silica; reducing, in one or more steps, the at least one metallic compound and the ruthenium compound to nickel and/or cobalt and ruthenium metal; and introducing halogen into the catalyst by adding a halide compound as a liquid, gas or in solution at any stage of the process.
