Influence of waveform of applied voltage on ethylene decomposition using dielectric barrier discharge (DBD) plasma reactor is investigated. A coaxial cylindrical DBD reactor is used. The nitrogen, oxygen and water vapor mixture gas is injected into the reactor, and its mixture ratio is varied. The rectangular and triangular wave voltages are generated using a high voltage amplifier, and pulsed voltages are generated using a magnetic pulse compression circuit, which are applied to the DBD reactor. The frequency is fixed at 1000 Hz. The pulse voltage has the highest energy efficiency for O3 production and C2H4 decomposition, and the triangular wave voltage is the lowest.
