Method for removing nitrogen oxides from an oxygen-containing flue gas stream

A process is disclosed for the plasma-catalytic production of ammonia. A gas stream containing nitrogen and water vapor is passed through an electrical gas discharge in the discharge space of which is arranged a catalyst which contains a catalytically active component of at least one metal which can be titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, iron, ruthenium, osmium, cobalt, rhodium, iridium, nickel, palladium, platinum, manganese or copper on a support.

Process for the plasma-catalytic production of ammonia

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.
