摘要：
An experimental plasma reforming reactor for conversion of CH4-CO2 to synthesis gas (syngas) has been developed, in which the plasma is generated by a nonthermal arc plasma torch with simple and compact structure. The effects of total flux of feed gases and the molar ratio of CH4/CO2 on syngas production, selectivities of H-2 and CO2 and energy conversion efficiency were investigated. It is proven that this kind of plasma is an effective way to reforming of CO2-CH4 with energy conversion efficiency of 5.25 mmol/kJ and energy efficiency of 81%. Moreover, the heat generated by the plasma can be fully utilized to activate catalyst.
