Ozone production using pulsed dielectric barrier discharge in oxygen

The production of ozone was investigated using a dielectric barrier dischar ge in Oxygen, and employing short-duration pulsed power. The dependence of the ozone concentration (parts per million, ppm) and ozone production yield (g(O-3)/kWh) on the peak pulsed voltage (17.5 to 57.9 kV) and the pulse re petition rate (25 to 400 pulses/s, pps) was investigated, In the present st udy, the following parameters were kept constant: a pressure of 1.01x10(5) Pa, a temperature of 26 +/- 4 degreesC, a gas now rate of 3.0 l/min and a g aseous gap length of 11 mm. A concentric coaxial cylindrical reactor was us ed. A spiral copper wire (1 mm in diameter) was wound on a polyvinylchlorid e (PVC) cylindrical configuration (26 mm in diameter) and placed centrally in a concentric coaxial electrode system with 4 mm thick pvc dielectric lay er adjacent to a copper outer electrode of 58 mm in internal diameter. Hv a nd current pulses were provided by a magnetic pulse compressor power source .
