The pulsed power with short pulse width is appropriate to produce pulsed streamer discharges for chemical reactors. A developed nanosecond pulsed power generator is used to drive the chemical reactors. Two applications of production of ozone and treatment of nitrogen oxides are tested for the reactors. In these two applications, a same coaxial reactor consisting of a wire and a cylinder is used basically but the number of the reactors connected in parallel is changed. The high efficiencies of ozone production and NOx treatment are measured respectively. The system efficiency of ozone production, including pulse power generation, is approximately 200 g/kWh. Besides, it found that the small changes of the transmission line and the connection between the transmission line and the reactor affect the efficiencies as well as the configuration of reactors. In the measurement, the use of a resistive divider deteriorated the efficiencies. In using short pulse as nanosecond pulse width, the technique to control pulsed power becomes significant.
