| 摘要 |
The invention relates to a method for the catalytic reduction of NOx in exhaust gases containing oxygen of a thermal engine (2), in one or more reduction catalytic converters (5, 8), according to which hydrocarbons of the fuel of the thermal engine (2) are introduced into the reduction catalytic converter(s) (5, 8). To prevent the formation of toxic or dangerous substances or gases during said NOx reduction, the method is characterised by the use of a gas mixture, which is produced from the fuel of the thermal engine (2) in a controlled manner in a catalytic reformer (4a, 4b) and/or in a fuel cell (9a, 9b), as the reductant for the reduction catalytic converter(s) (5, 8). |
