PCT No. PCT/FR94/01048 Sec. 371 Date Jul. 14, 1995 Sec. 102(e) Date Jul. 14, 1995 PCT Filed Sep. 6, 1994 PCT Pub. No. WO95/07234 PCT Pub. Date Mar. 16, 1995A process for the conversion of N2O into NOx (x=1 or 2) thereof, comprising forming a jet of gas to be treated comprising N2O and directing the jet into the interstitial space of at least two divergent electrodes placed under an electric voltage, to create at least one electric discharge and/or arc, and is part of a low-temperature plasma generator. The generator works by formation of electric discharges sliding between the electrodes such that the gas circulates along the electrodes from the discharge region where these electrodes are closest to each other. Finally, the NOx gas formed is recovered. The invention also relates to a device for carrying out the process.
