Radiation treatment of exhaust gases, (9)

The computer simulation method has been applied to the analysis of the NO and NO2 decomposition in the NO-N2 and NO2-N2 mixtures by electron beam irradiation. The calculated results regarding the NO and NO2 decomposition were in good agreement with the experimental results in both mixtures. The NO and NO2 decomposition is mainly induced by the radical reactions and is hardly induced by the ion reactions. That is, the NO decomposition in the NO-N2 mixture is mainly induced by the attack of N formed by the radiolysis of N2 decomposition in the NO2-N2 mixture is induced not only by the attack of N, but also by the attack of O formed through the reaction of NO2 with N at low doses. At high doses, the decomposition of NO formed through the reactions of NO2 with N and with O is mainly induced by the attack of N, in contrast to the NO2 decomposition by the attacks of N and O at low doses. The G value of the formation of N(G(N)) by the computer simulation was 2.0. (author)
