Abstract

The purpose of this study was to develop technology that can convert biogas to synthesis gas (SynGas), a low emission substituted energy, using a non-thermal pulsed plasma method. To investigate the characteristics of the SynGas production from simulated biogas, the reforming characteristics were studied about the variations of pulse frequency, biogas component ratio (C₃H₈/CO₂), vapor flow ratio (H₂O/TFR), biogas velocity and pulse power. A maximum conversion rate of 49.1% was achieved for the biogas when the above parameters were 500 Hz, 1.5, 0.52, 0.32 m/s and 657W, respectively. Under the above-mentioned reference conditions, the dry basis concentrations of the SynGas were, H₂ 64.5%, CH₄ 8.1%, C₂H₂ 6.7%, C₃H₆ 4.9%, CO 0.8% and C₂H₄ 0.4%. The ratio of hydrogen to the other intermediates in the SynGas (H₂/ITMs) was 3.1.
