CH4 conversion into H2 is investigated in a nanosecond pulsed DBD reactor.
The absence of CO and CO2 in the product gas is highly favorable.
Effects of external electrode length, applied voltage and frequency are examined.
The maximum efficiency of 7.23% is achieved at the electrode length of 15 cm.
The maximum CH4 conversion of 87.2% is obtained at discharge power 268.92 W.
