CATALYSTS

摘要

A process is described for the preparation of a supported cobalt catalyst comprising the steps of; (i) mixing a support material with a solution of a thermally decomposable cobalt ammine carboxylate complex, e.g. cobalt ammine formate, to form a catalyst precursor, (ii) separating any excess solution from the catalyst precursor, (iii) drying the catalyst precursor, and (iv) heating the dried catalyst precursor under non-oxidising conditions so that at least part of the cobalt is converted to its elemental form. The catalyst may be used for the hydrogenation of unsaturated compounds or the Fischer-Tropsch synthesis of hydrocarbons.
