Abstract :
Nitrogen oxides (NOX) are one of the air pollutants and cause acid rain. The method of NOX treatment using dielectric barrier discharges has been developed. Pulsed power is able to produce streamer discharges without barrier material. The treatment with high efficiency and break-proof reactors, therefore, are expected by application of pulsed power. Moreover, shortening of the pulse width would improve the efficiency of treatments. The pulsed power with pulse width of approximately 1 ns is applied to the NOX treatment. The reactor consists of the coaxial electrodes connected parallel is used for the treatment. The gas of NO/N2 is used. The maximum NO removal efficiency is around 0.3 mol/kWh on the experimental condition. The removing ratios of both NO and NOX reach up to near 100% when the energy deposited in the gas is enough for the treatment. The number of parallel reactors obtaining maximum efficiency for higher initial concentration of NO is larger than that for lower initial concentration.
