NO removal and discharge characteristics using dielectric barrier discharge

Abstract

An experimental study on NO removal was undertaken using cylindrical dielectric barrier discharge (DBD). The aim is to investigate reaction pathway and the role of reactive species such as O, O3 and OH for NO removal. Under different concentration of O2, H2O and NO, the dominant reactive species was investigated quantitatively. In addition, according to the feed gas compositions, the magnitude of filamentary discharge current would change from a few mA to more than one hundred mA.
