Abstract

The present invention relates to a process for the hydrogenation, in particular selective hydrogenation of at least one unsaturated hydrocarbon compound comprising reacting the at least one unsaturated hydrocarbon compound with hydrogen in the presence of a hydrogenation catalyst, wherein the hydrogenation catalyst comprises a mixture of an ordered intermetallic compound and an inert material. According to another aspect, the present invention is concerned with the use of a mixture of at least one ordered intermetallic compound and at least one inert material, as a catalyst. The mixtures for use as a catalyst in the present invention can be prepared easily and achieve a superior activity in relation to the prior art, while preserving the high selectivity to the target compounds, e.g. in the selective hydrogenation of acetylene to ethylene.
