Abstract

An experimental study on the conversion of NO in the NO/O₂/N₂ system has been carried out using Dielectric Barrier Discharge (DBD) Plasma at atmospheric pressure. The emphases are on energy consumption and the efficiency for NO conversion in the system. By measuring the concentration of NO and NO₂ as a function of specific energy density (SED), it is possible to determine the energy consumption for NO conversion and the effect of O₂ concentration and NO initial concentration on the efficiency for NO. It is conformed in this study that NO to NO₂ is the main reaction in the NO/O₂/N₂ system; the efficiency for NO conversion is reduced with the increase of O₂ concentration, the yield of NO₂ increases with the increase of O₂ concentration; initial concentration of NO is smaller, the efficiency for NO conversion is higher. When initial concentration of NO is 260times10^-6 in the system, 75-95% NO can be conversed in the SED range of 440-700 J/L.
