Abstract

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.
