Abstract This paper describes experimental results of NO removal from a simulated exhausted gas using a barrier‐type plasma reactor subjected to reciprocal traveling wave voltage pulses. A pulse‐forming cable was charged and then grounded at one end without any resistance, so that a traveling wave reciprocated along the cable with a change in its polarity because the traveling wave was negatively reflected at the grounded end. Transient discharge light between point‐plane electrodes with a glass barrier was observed using a gated image‐intensifier. Photographs of the transient discharge light indicated that many streamer channels extended widely in the gap at the initial stage of voltage oscillation, while only an intense discharge channel was observed at the latter stage. NO removal tests were performed using the reciprocal pulse generator and a coaxial plasma reactor with a cylindrical glass barrier. The results indicated that the discharges at the first and second polarity reversals contributed greatly to the oxidation reaction from NO into NO 2 , whereas the contribution of the subsequent discharges in the latter stage to NO removal was small. © 2008 Wiley Periodicals, Inc.
