Oxidant effects on the promotion of no removal by non-thremal plasma

Summary form only given. Plasma remediation is being investigated for the removal of nitrogen oxide from automotive exhausts and gases generated by combustion of fossil fuels. Modeling is playing an increasing vital role in process optimization and understanding of governing physical and chemical process. In this paper, chemical kinetics of the plasma-induced reactions is elucidated by variation of the initial concentration of NO and from chemical kinetics calculations. A reduced plasma chemistry model, in which radical reactions are selectively involved, is validated with experimental data. A qualitative model is presented which can explain the characteristic kinetics of the reactions in the plasma. In the presence of both these oxidants, more than 80% of the NO conversion is oxidation. Chemical kinetics calculations of the production of radicals in the plasma show a good agreement with the value derived from the experiments
