Abstract
Destruction of isotopicaliy enriched nitric oxide (15N18O) in air in corona discharge was studied using a tubular flow coaxial wire AC dielectric barrier discharge reactor coupled to a quadrupole mass- spectrometer. The experiments were performed at ambient temperature and pressure (298 K, 1 bar) with 0.04% and 1.02% mixtures of 15N18O(15N 99.8 atom. %, 18O 99.0 atom. %) in synthetic air (21% O2, 79% N2). At low energy densities (< 2 J/cm3 for 1.02% mixture), an efficient scrambling of oxygen isotopes and conversion of NO to NO2 is observed. These observations are rationalized based on the fast symmetric isotope exchange reactions of nitrogen oxides with oxygen atoms and the reaction of nitric oxide with ozone. At higher energy densities, formation of molecular nitrogen is observed. Processes of reduction of NOx, initially present in the mixture, and formation of additional NOx in corona discharge are clearly separated due to the isotopic substitution. The energies required for the conversion of NO to NO2 and for the reduction of NOx to N2 are 22 eV/molecule (51 g(NO)/kWh) and 470 eV/molecule (2.4 g(NO)/kWh), respectively.
