Beschreibung
Zusammenfassung:	The present invention relates to a novel noble metal supported catalyst and its preparation an use for the hydrogenation of unsaturated hydrocarbons. The catalyst is obtainable by impregnating an aluminium oxide support material having an internal surface area (BET) of less than 80 m2/g to saturation with an aqueous solution containing an inorganic base, drying the material in a stream of warm air an impregnating it in a manner which is in itself known with a noble metal salt solution, 0.1 to 50 gram equivalents of organic base being employed per gram equivalent of noble metal. The catalysts of this invention show both high activity and high selectivity, coupled with a relatively low cost as a result of the smaller amounts of valuable noble metal used.
