ABSTRACT

The aim of this work is to analyze the time behavior of different species and their reaction rates using a zero-dimensional model based on chemical kinetic equations. The considered model is able to describe the behavior of twenty different chemical species participating in one hundred selected chemical reactions. In general, certain radicals N, O, and O3 participate in the NOX removal. In this work, we complete these studies by analyzing other species such as negative ions (i.e., O2, O3, and O4) and radicals O3 and OH present in a N2/O2/H2O/CO2 mixture. In particular, we have analyzed at various times in the ranges 10−9−10−3 s of the rate coefficient and depopulation rate of certain reactions, under different fields. The obtained results show the significant reduction in the concentration of NO, NO2, and NO3.
