Abstract

In the paper analysis of chemical reaction in a mixture of N₂ (70%), O₂ (5%), CO₂ (15%), H₂O (10%), NO (400 ppm), simulating flue gas, subjected to a nonthermal piasma generated by a continuous :.ectron beam or to a pulsed positive corona discharge is presented, A special attention was put on reactions responsible for conversions of NO, NO₂ and N₂O. A method of modelling of chemical reactions kinetics in the nonthermal plasma in the flue gas simulator is presented as weli. It is shown in the paper that processes of NO_x removal from flue gas in the nonthermai plasma generated by the e-beam or the corona discharge are similar, i.e. removal of NO_x is based on oxidizing reactions of NO and NO₂ with OH :"Cicals. However, there are some significant differences in the chemical kinetics of the e-beam plasma and the corona discharge plasma, in particular, in the chemicai kinetic of ions and production of radicals e.g. OH radicals).
