PROBLEM TO BE SOLVED: To hydrogenate polyunsaturated hydrcarbon(s) in a fluid by bringing the hydrocarbon(s) into contact with a catalyst pack in the presence of free hydrogen. SOLUTION: Polyunsaturated 2-8C hydrocarbon(s), esp. 2-8C alkyne and/or 4-8C alkynene and/or 4-8C alkadiene, is brought into contact with a catalyst pack in the presence of free hydrogen. The catalyst pack is prepared by applying an active substance as a catalyst and/or promoter to a woven mesh, knitwear or foil as support material; for example, the support may be coated with the catalytically active compound and promoter by e.g. vacuum deposition. By virtue of using the catalyst, the polyunsaturated hydrocarbon(s) can be converted to the corresponding monounsaturated hydrocarbon(s) in high selectivity and yield, and hydrogenation of isobutene does not occur. |
