| Zusammenfassung: | The present invention relates to a process for the selective catalytic reduction of nitrogen oxides contained in a lean-mix exhaust gas from combustion engines by reducing the nitrogen oxides by means of ammonia on a catalyst.
The invention relates to a process for the selective catalytic reduction of the nitrogen oxides contained in a lean exhaust gas from internal combustion engines by reducing the nitrogen oxides by means of ammonia on a catalyst. The process is characterized in that, in addition to the lean exhaust gas, a rich gas stream is produced that is treated in an electrical gas discharge plasma in order to form the ammonia required for the reduction. |
