Comparison of different applied voltage waveforms on CO2 reforming of CH4 in an atmospheric plasma system
E-mail:
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 H2 and CO. It was confirmed that CO2 reforming of CH4 can be improved by the a daption of pulse-type power supply in a dielectric barrier discharge reactor immersed in an electrically insulating oil bath.
