  • Publication number: 20220010712
    Abstract: An exhaust emission control device has at least one exhaust gas line, at least one particulate filter and/or at least one exhaust gas catalytic converter connected to the exhaust gas line, and a heated catalyst assembly arranged upstream of the particulate filter and/or the exhaust gas catalytic converter. The heated catalyst assembly is designed to react fuel with exhaust gas, and has a housing provided with an inlet and an outlet connected to the exhaust gas line such that a partial flow of the exhaust gas flowing in the exhaust gas line can be fed through the inlet into the housing and can be discharged from the housing through the outlet back into the exhaust gas line downstream of the inlet. An exhaust emission control device of this type may be used in conjunction with an internal combustion engine, and may be used for emission control of exhaust gas.

  • Publication number: 20200370514
    Abstract: A method is described for operating a catalytic evaporator (1), with the step: feeding fuel and an oxidant to the catalytic evaporator, which method is distinguished by the fact that (a) the feed of the fuel is performed as a pulsed feed, and/or (b) the feed of the oxidant is performed as a pulsed feed.

  • Publication number: 20180266676
    Abstract: The ignition characteristics of a fuel are adjusted using a unit which has a distribution zone, a oxidation zone and a conversion zone. Fuel is distributed in the distribution zone having a distribution structure. A portion of the fuel is oxidised in the oxidation zone with a oxidising agent on a catalyst on a catalyst carrier, and a portion of the distributed fuel and/or of another supplied fuel is thermally and/or catalytically converted in the conversion zone. The ignition characteristics of the fuel are adjusted via: the molar ratio of oxygen included in the oxidising agent to the oxygen required for the complete oxidation of the fuel provided; and/or via the pressure in the unit; and/or the dwell time; and/or the temperature. Exhaust emissions, in particular NOx and soot emissions, can be lowered.

  • Patent number: 9074508
    Abstract: The present invention relates to an exhaust-gas purification device by means of which combustion exhaust gases emerging from combustion devices, in particular diesel engines, can be purified. At least a regeneration of the soot particle filter and/or the NOx catalytic converter can be attained by means of the exhaust-gas purification device.

  • Patent number: 7820588
    Abstract: The invention relates to a catalyst for the oxidation of carbon monoxide (CO) at low temperatures, which is a catalytically active composition based on platinum and cobalt. The catalyst can be used in the removal of CO from hydrogen-rich gas for fuel cell technology in order to avoid poisoning the electrodes with CO. Further fields of application relate to the automobile sector, and in particular, to the effective removal of CO during cold starting of a diesel or petrol engine and also to air purification systems for quality control of air in interior spaces, e.g., the removal of CO in a tunnel, an underground railway, multi-story car parks or submarines.
