PROCESS FOR PLASMACHEMICAL TRANSFORMATION OF N2O INTO NOx AND/OR INTO DERIVATIVES THEREOF

摘要

The present invention relates to a process for the transformation of N2O into NOx (x = 1 or 2) and/or into its derivatives, comprising forming a gas jet to be treated including N2O; directing said jet into the interstitial space (11) of at least two divergent electrodes (10a-10f) to which an electric voltage is applied in order to create at least one arc and/or one electric discharge and being part of a low temperature plasma generator (4), the latter operating by formation of electric discharges sliding between the electrodes (10a-10f), so that the gas circulates along the electrodes from the area (11) of discharges and/or arcs from the aera of arcs and/or discharges where said electrodes are the closest to each other; and recovering the gas containing the NOx formed. The invention also relates to a device for implementing such process. Application: N2O valorization.
