    摘要: Supported palladium-gold catalyst of high resistance to poisoning by sulfur compounds, not subject to elution by vinylacetylene and not inducing a substantial formation of oligomers, for use in hydrogenation reactions wherein acetylenics and diolefins are selectively hydrogenated, said catalyst being obtained by the steps of: admixing a palladium compound with an inorganic carrier, roasting in the presence of an oxygen-containing gas, treating with a reducing agent, admixing a halogenated gold compound with the resulting composition, treating with a reducing agent, treating with a compound having a basic reaction so as to lower the halogen content of the catalyst below 10 ppm by weight, and roasting, in the presence of an oxygen-containing gas, the palladium and gold compounds being used in convenient proportions so that the catalyst contains 0.03 to 1% palladium and 0.003 to 0.3% gold by weight.

    摘要: Disclosed is a process for selective hydrogenation in liquid phase of an effluent originating from an ethane steam cracker in which said effluent is contacted with a catalyst consisting of at least supported palladium characterized in that it is carried out in the presence of a liquid phase containing at least part of the hydrogenated gasoline cut, condensed and recycled, of said effluent.Said effluent (1), said liquid phase (8) and possibly hydrogen (13) pass through the hydrogenation reactor (4). The product obtained is fractionated (5) into a gaseous cut at the top (7) containing ethylene and a liquid gasoline cut at the bottom which is partially recycled (8).The process may be used for production of ethylene and for production of gasoline.
