Comparison of different applied voltage waveforms on CO2 reforming of CH4 in an atmospheric plasma system

초록

Sinusoidal and pulse waveforms of applied voltage were employed for CO2 reforming of CH4 to syngas in an atmospheric dielectric barrier discharge reactor. The discharge power of a pulse waveform was higher than that of sinusoidal waveform at the same applied voltage. The plasma reaction by a pulse waveform enhanced the conversion of CO2 and CH4 and the selectivity of H-2 and CO. It was confirmed that CO2 reforming of CH4 can be improved by the adaption of pulse-type power supply in a dielectric barrier discharge reactor immersed in an electrically insulating oil bath.
