Patent number: 11952931Abstract: 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.Type: GrantFiled: September 27, 2021Date of Patent: April 9, 2024Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Robert Szolak, Alexander Susdorf

Patent number: 11781747Abstract: 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.Type: GrantFiled: May 18, 2018Date of Patent: October 10, 2023Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Thomas Aicher, Robert Szolak, Alexander Susdorf

Patent number: 7820588Abstract: 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.Type: GrantFiled: December 1, 2006Date of Patent: October 26, 2010Assignees: Ford Global Technologies, LLC, Fraunhofer-GesellschaftInventors: Albert Chigapov, Brendan Carberry, Alexander Susdorf
