Abstract
An experimental study on the conversion of NO in the NO/O 2 /N 2 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 NO 2 as a function of specific energy density (SED), it is possible to determine the energy consumption for NO conversion and the effect of O 2 concentration and NO initial concentration on the efficiency for NO. It is conformed in this study that NO to NO 2 is the main reaction in the NO/O 2 /N 2 system; the efficiency for NO conversion is reduced with the increase of O 2 concentration, the yield of NO 2 increases with the increase of O 2 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.
