The hydrogenation manner which uses the catalytic converter which includes the systematic conversion intermetallic compound

摘要

The present invention relates to a process for the hydrogenation and in particular the selective hydrogenation of unsaturated hydrocarbon compounds using a hydrogenation catalyst comprising an ordered intermetallic compound. The ordered intermetallic compound comprises at least one metal of type A capable of activating hydrogen, and at least one metal of type B not capable of activating hydrogen and the structure of the ordered intermetallic compound is such that at least one king of type A metals is mainly surrounded by atoms of the metal of type B. According to another aspect and the present invention is concerned with a catalyst comprising a support and the above ordered intermetallic compound supported ON the support. According to still another aspect and the invention pertains to the use of a binary Pd-Ga ordered intermetallic compound as a catalyst. The hydrogenation process and catalysts of the present invention achieve a selectivity to the target compounds, e.g in the selective hydrogenation of acetylene to ethylene and which is superior to the prior art.
