Abstract: PROBLEM TO BE SOLVED: To provide a highly dispersed active component and to ensure high sintering stability and aggregation stability by applying a catalytically active metal to a support modified in the form of a chloride-free dissolved amine complex, acetylacetonate complex or allyl complex. SOLUTION: An inner support material such as granular SiO2 is pretreated by heating before coating with a modifier preferably used in the form of an alkoxide. The inner support material is then impregnated into a liquid phase, e.g. in an aqueous or organic phase or into a gaseous phase, e.g. by chemical vapor deposition. The resulting support material modified in the form of a chloride-free amine complex, acetylacetonate complex or allyl complex is optionally hydrolyzed, dried and calcined. A catalytically active metal such as Pd or Pt is applied to the modified support material by impregnation or ion exchange and then drying and optional calcination are carried out.

Abstract: Catalyst contains a catalytically active metal in the form of its chloride-free dissolved amine complexes, aetylacetonate or allyl complexes on a modified carrier. An Independent claim is also included for a process for the production of the catalyst comprising: (a) thermally treating the carrier material; (b) impregnating the carrier material with a modifier in the gas or liquid phase; (c) optionally hydrolyzing the modified carrier material at 20-200 degrees C in O2 or in air or in a H2O-containing gas stream; (d) optionally drying at 100-500 degrees C; (e) optionally calcining at 200-1000 degrees C; (f) applying the catalytically active metal by impregnating or ion exchange; (g) drying at 20-500 degrees C; and (h) optionally calcining at up to 1000 degrees C.
