  • Patent number: 11808189
    Abstract: The invention relates to a method for producing a wall-flow filter for removing fine particulate solids from gases, and to the use thereof for cleaning exhaust gases of an internal combustion engine. The invention also relates to a correspondingly produced exhaust-gas filter having a high filtration efficiency.
    Type: Grant
    Filed: November 7, 2019
    Date of Patent: November 7, 2023
    Assignee: UMICORE AG & CO. KG
    Inventors: Manuel Gensch, Martin Foerster, Naina Deibel, Antje Oltersdorf, Juergen Koch
  • Publication number: 20230127269
    Abstract: The invention relates to a wall-flow filter as a particle filter with catalytically active coatings in the channels which are closed in a gas-tight manner at the opposing closed ends of the channels A at the first end, wherein the inlet region of the filter is additionally supplied with a dry powder-gas aerosol which contains metal compounds with a high melting point (such as the metal oxides Al203, Si02, Fe02, Ti02, Zn02, etc. for example) and which is to simultaneously improve the catalytic activity and the degree of filtration efficiency with respect to the exhaust gas back-pressure.

  • Patent number: 11441459
    Abstract: The present invention relates to a wall-flow filter, to a method for the production and the use thereof in order to reduce harmful exhaust gases of an internal combustion engine. The wall-flow filter was produced by applying a powder-gas aerosol to the filter, whereby the powder was deposited in the pores of the wall-flow filter.
