  • SCR catalyst having improved adhesion of the zeolite-containing catalytic layer
    Patent number: 10150103
    Abstract: The invention relates to: a catalytic composition that is active in the selective catalytic reduction of nitric oxides, containing an iron-containing MFI-type zeolite and an iron-containing BEA-type zeolite, wherein the weight average particle size d50 of the MFI-type zeolite and the BEA-type zeolite is different; a method for producing an SCR catalyst; and the SCR catalyst produced in this way. The adhesion of the coating is improved in that the weight average particle sizes of the MFI-type and BEA-type zeolites are different.
    Type: Grant

  • COPPER-CONTAINING KFI-TYPE ZEOLITE AND USE IN SCR CATALYSIS
    Publication number: 20170050179
    Abstract: The present invention relates to a copper-containing KFI-type zeolite, wherein the zeolite contains 1 to 4.5 wt.-% copper. The invention is also directed towards a method for producing the copper-containing zeolite according to the invention as well as towards the use of the zeolite in SCR catalysis. Further subjects of the invention are a washcoat which contains the zeolite according to the invention, an SCR catalyst which contains the zeolite according to the invention as well as an exhaust-gas cleaning system which comprises the SCR catalyst.
