Abstract: 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.

Abstract: Alkines, dienes, and/or singly unsaturated hydrocarbons; compounds containing sulphur, arsenic and/or antimony; oxygen, hydrogen and/or carbon monoxide are removed from material flows in a total of at most three process steps. In a first process step, after hydrogen has been added to the feed material flow at a hydrogenation catalyst which is largely resistant to compounds containing sulphur, arsenic and/or antimony, alkines, dienes and/or singly unsaturated hydrocarbons are removed by hydrogenation, oxygen which may optionally be present also being at least partially removed by hydrogenation. In a second process step, compounds containing sulphur, arsenic and/or antimony and/or residual oxygen from the first process step are removed by absorption on a contact mass, and/or residual oxygen, carbon monoxide and/or residual hydrogen are at least partially converted catalytically into water and carbon dioxide. Optionally, in a third process step, residual carbon monoxide and/or residual hydrogen from the preceding process steps is/are converted on a contact mass into carbon dioxide and/or water.

Abstract: The proposed process for preparing a hydrogenation catalyst based on aluminium alloy and a transient metal is characterized by preparation of a kneading material from the alloy and an auxiliary agent, the kneading material is then formed to shaped bodies, the shaped bodies are subjected to calcination and the calcined shaped bodies are then treated with an alkali metal hydroxide, whereby the auxiliary agent is represented by (a) polyvinyl alcohol and water or (b) stearic acid. The catalyst is intended for hydrogenation and hydrogenolysis, particularly a partial hydrogenation of aliphatic alpha, omega-dinitriles to aliphatic alpha, omega-aminonitriles.
