Description
Fundamental characteristics of N_2O decomposition by atmospheric non-equilibrium plasma were investigated to reduce greenhouse effects under an atmospheric temperature without catalysts. A pulsed dielectric barrier discharge (DBD) with a one-cycle sinusoidal-wave power source was employed. Plasma conditions (applied voltages and its repetition rates), gas composition, and gas flow rate were varied. In N_2O-O_2-Ar system, an N_2O concentration of 30 ppm was completely decomposed by DBD at O_2 = 0%, but the rate of N_2O decomposition was decreased with increasing O_2 concentration. The energy efficiency was 0.5 g-N_2O/kWh. Unfortunately, in N_2O-O_2-N_2 system : N_2O in actual flue gas was not decomposed by DBD under excess O_2. Formation and decomposition mechanisms of N_2O were experimentally discussed. N_2O formation, N_2 + O → N_2O, is a dominant reaction below O_2 = 5% in nitrogen rich gas.
