  • Patent number: 9669397
    Abstract: A metal-doped or metal-exchanged zeolite is disclosed, wherein the doping metal is present in the zeolite in the form of individual atoms i.e. as monomeric and/or dimeric species. Further, a process for the preparation of such a metal-doped or metal-exchanged zeolite is disclosed. The metal-doped zeolites are useful, in particular, as catalysts for the reduction of nitrogen oxides.

  • Patent number: 9018120
    Abstract: The present invention provides a process for the preparation of metal-doped zeolites comprising the steps of i) provision of a dry mixture of a) a zeolite, b) a compound of a catalytically active metal, ii) intimate grinding of the mixture, iii) heating of the mixture in a reactor, iv) cooling to room temperature and obtaining the metal-doped zeolite, wherein the internal pressure in the reactor during the heating is kept in a pressure range from 0 to ?200 millibar. The invention further relates to the use of a metal-doped zeolite prepared by means of the process according to the invention for the conversion of NOx and N2O into harmless products.
