Description

The computer simulation method has been applied to the analysis of the NO oxidation and decomposition in the dry and moist NO-O2-N2 mixtures by electron beam irradiation. The calculated results were in good agreement with the experimental results for both mix-tures. The NO in the dry NO-O2-N2 mixture is decomposed by the reaction with N(4S) formed by the radiolysis of the O2-N2 mixture and is oxidized by the reactions with 0 and with O3 formed through the reaction of O2 with O. The NO in the moist NO-O2-N2 mix-ture is oxidized not only by the reaction with OH formed by the radiolysis, but also by the reaction with O3 formed through the reaction of O2 with O at low dose. The G values of the formations of the active species obtained by the computer simulation were G(N(4S))=1.1, G(N(2D))=0.9 and G(O)=1.7 for the dry NO-O2-N2 mixture and G(O)=2.0 and G(HO2)=0.17 for the moist NO-O2-N2 mixture, Also, the analysis by the computer simulation con-firmed the value of G(OH)=3.2 obtained in the moist O2-N2 mixture by the competition method.
