Nonthermal Plasma Reactions of Dilute Nitrogen Oxide Mixtures: NOx in Nitrogen

A lumped kinetic model of a pulsed corona discharge reactor, where the high-voltage discharge-induced electron density fluctuation and hence the electron collision rate fluctuation are approximated with a uniform electron distribution and a new Arrhenius-type rate model, is found to capture the effect of power input, NO x composition, and residence time. An N atom and N 2 (A) are found to control the conversion of nitrogen oxides and the evolution of byproducts; the N atom controls the NO conversion, N 2 (A) controls the N 2 O conversion, and the N atom and N 2 (A) control the NO 2 conversion.
