| abstract |
The invention relates to a process for preparing a halogen-containing nickel and / or cobalt catalyst having ruthenium promoter, the 4 to 40 wt .-%, based on the total mass of the catalyst, at least one nickel and cobalt selected metal, 0.1 to 5% by weight based on the total mass of the catalyst, ruthenium, and a porous metal oxide support consisting of at least 50% by weight of activated clay and / or silica, wherein the support comprises in the process in one or more steps a nickel compound and / or a cobalt compound and a ruthenium compound is impregnated and the nickel and / or cobalt compound and the ruthenium compound are reduced to finely divided nickel and / or cobalt and ruthenium. According to the invention, a hologenide is introduced into the catalyst by adding a halide compound in any form other than a ruthenium halide compound at any stage of the process. |
