In a process for the catalytic NO<SUB>x </SUB>reduction in oxygen-containing exhaust gases of a thermal engine in one or several reduction catalytic converters, hydrocarbons of the fuel of the thermal engine are used in the reduction catalytic converter(s). In order to avoid toxic or dangerous substances and gases, respectively, during said NO<SUB>x </SUB>reduction, the process is characterized by the use of a gas mixture as a reducing agent for the reduction catalytic converter(s), which gas mixture is produced in a controlled manner from the fuel of the thermal engine in a catalytic reformer and/or in a fuel cell. |
