Abstract
The effect of O2 and H2O vapor on the Nitric oxide (NO) removal rate, the NO2 generation rate and the discharge characteristics were investigated using the dielectric barrier discharge (DBD) reactor at 1 atm pressure and at room temperature (20°). The results showed that the O2 present in the flue gas always hampered the removal of NO and the generation of N2O, but that the O2 could enhance the generation of NO2 in the NO/N2/O2 mixtures. Furthermore, with the increase of oxygen, the average discharge current gradually decreases in the reactor. The H2O present in N2/NO hindered the removal of NO and the generation of NO2 but had no impact on the average discharge current in the reactor in the NO/N2/H2O mixtures in which the HNO2 and HNO3 was detected. The energy efficiency of the DBD used to remove the NO from the flue gas was also estimated.
