  • Method and apparatus for the purification of exhaust gas from a compression ignition engine
    Patent number: 8603941
    Abstract: A method and apparatus for the removal of NO2 emission from a lean burn compression ignition engine, wherein NO2 containing engine exhaust gas is brought in contact with a catalyst being active in the reduction of NO2 to NO and comprising at least one platinum group metal with the proviso that the platinum metal is not platinum and at least one redox active metal oxide and thereby reducing NO2 contained in the exhaust gas to NO by reaction with CO, hydrocarbons and/or soot being present in the exhaust gas.
    Type: Grant
    Filed: October 11, 2007
    Date of Patent: December 10, 2013
    Assignee: Haldor Topsoe A/S
    Inventors: Søren Dahl, Keld Johansen, Søren Pehrson, Gurli Mogensen
  • Diesel particulate filter
    Patent number: 7625538
    Abstract: The invention provides a process and filter for catalytic purification of exhaust gas from a diesel engine by passing the exhaust gas through a wall flow filter provided with material being catalytic active in the reduction of nitrogen oxides to nitrogen and oxidation of carbonaceous compounds to carbon dioxide and water. The wall flow filter is prepared from silicon carbide and provided with a layer of titanium dioxide on its surface and wherein the catalytic active material comprises oxides of vanadium, tungsten and metallic palladium.
