Nitrogen oxides (NOx) are one of the air pollutants that cause acid rain. While utilization of catalysts is a typical method of NOx treatment to remove, the treatment using pulsed power has been developed. A nanosecond pulsed power generator has been developed and NOx treatment experiment is conducted. As the width of pulsed power shortens, the efficiency of treatment will be improved but the issues in using nanosecond pulses have appeared: difficulties of load matching and optimization of the discharge reactor. Then, the parallel- and serial-connections of reactors are considered. The reactor consists of wire and cylinder electrodes and has a coaxial structure. Efficiency of the parallel connection was higher than the serial connection. In this experimental condition, three parallel reactors yielded the highest efficiency in the all reactor configurations. Since load matching is an important matter for nanosecond pulsed power, the parallel or serial connection would improve the treatment efficiency. The configuration of reactors for high efficiency of NOx treatment will be reported in detail.
