A method for exhaust gas post treatment is provided, comprising the following steps: a) providing a nitrogen oxide-containing raw exhaust gas, b) introducing the nitrogen oxide-containing raw exhaust gas into a catalytic evaporator (), c) introducing a fuel into the catalytic evaporator (), whereby a converted fuel is obtained, d) mixing urea with the converted fuel, and e) feeding the mixture obtained after step d) into an exhaust gas post treatment system (). Alternatively or in addition, a device may be provided for exhaust gas post treatment.

Device and method for exhaust gas post treatment and use thereof

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.

Exhaust emission control device, internal combustion engine equipped therewith and method for exhaust emission control

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.

Method and apparatus for setting the ignition property of a fuel

A method is described for operating a catalytic evaporator (), 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.

Method for operating a catalytic evaporator and uses of the method

A method for exhaust gas aftertreatment is provided, the method comprising: a) providing a nitrogen oxide-containing raw exhaust gas, b) introducing the nitrogen oxide-containing raw exhaust gas into a catalytic evaporator (), c) introducing a urea solution and a fuel into the catalytic evaporator (), as a result of which a reducing agent is obtained, and d) supplying the reducing agent to an exhaust gas aftertreatment system (). Alternatively or in addition, a device for producing a reducing agent may be provided, a reducing agent produced with same, and the use of these objects.

Exhaust gas aftertreatment

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.

Exhaust-gas purification device, method for exhaust-gas purification, catalytic converter and pyrolysis reactor

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.

Carbon monoxide catalyst

Disclosed is a mixed oxide catalyst, preferably for selective oxidation of CO in hydrogen rich gas mixtures, or in oxygen containing gas mixtures in the presence of water and carbon dioxide, comprising about 15 to 30 at.-% Cu, about 55 to 77 at.-% Mn and about 7.5 to 10 at.-% Ce.
