PERSPECTIVE OF NOx REMOVAL FROM NUMERICAL SIMULATION OF NON-THERMAL ATMOSPHERIC PRESSURE PLASMA CHEMICAL KINETICS
RESUMO
We present results of numerical simulations of the chemical kinetics in the gas-phase of air discharges at high pressure which operates in a streamer regime. We have studied theoretically the effect of the presence of small amounts of contaminants such as nitrogen oxides, in particular NO in the initial gas mixture. Simulation of a single isolated streamer and the detailed temporal evolution of the discharge gas phase was studied, showing the interplay between different time scale processes. Removal of NO from the gas-phase of a single discharge was reported when the initial concentration is below a few hundreds ppm. We have also evaluated the total amount of NO that could be processed by a repeated discharge operation. Results can prove relevant for a better understanding of the operating conditions under which NOx remediation is feasible using this kind of atmospheric pressure plasmas.
