Abstract

Selective hydrogenation of unsaturated hydrocarbon compounds, e.g. of acetylene to ethylene, uses 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. The structure of the ordered intermetallic compound is such that the type A metal is mainly surrounded by atoms of the type B metal.
