Abstract: | The purpose of this work is to investigate the contribution of different chemical reactions that participate in NOx creation or reduction in N2/O2/H2O/CO2 mixed gas induced by negative corona discharge under different reduced electric field levels:100 - 200 Td (1Td=10−21 V.m2). The fundamental chemistry governing NOx evolution developed in this paper is based on a full set of processes regrouped in 200 selected chemical reactions involving 36 molecular, excited, atomic, and charged species. The density was calculated using the continuity equation while not the diffusion term, and the time analysis varied from 10−9 to 10−3s. The results of simulations show the role played by different chemical reactions on NOx conversion. It is shown that at 100 Td near 60% of NO can be removed by radical through the reaction NO + → + O2 and near 20% of NO2 and NO3 could be removed by radicals and through NO2 + → + O3 and NO3+ → N O2 respectively. |
