  • Use of a mixture of an ordered intermetallic compound and an inert material as a catalyst and corresponding hydrogenation processes
    Patent number: 8519207
    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.

  • Methods of Preparing, Optionally Supported, Ordered Intermetallic Palladium Gallium Compounds, the Compounds, as such, and Their Use in Catalysis
    Publication number: 20100261939
    Abstract: The present invention pertains to methods of preparing optionally supported, ordered intermetallic palladium gallium compounds, and the corresponding, optionally supported, intermetallic palladium gallium compounds obtainable by these methods. The present invention also pertains to the use of the optionally supported ordered intermetallic palladium gallium compounds as catalysts, such as in selective hydrogenations of alkynes, in particular ethyne, to give the corresponding alkenes. The optionally supported, ordered intermetallic palladium gallium compounds were found to be highly active and selective catalysts in the above hydrogenation reactions.
