Carbon Dioxide Reforming of Methane to Syngas by Warm Plasma: Low Energy Consumption

Experimental study of warm plasma reforming carbon dioxide and methane to syngas is presented. To achieve better plasma reforming methods for industrial chemical application, the characteristics of the different plasmas are reviewed. The warm plasma combines advantages of both thermal and non-equilibrium discharge, which is the more potential for industrial application than others plasmas, such as arc, DBD, corona. The effects of discharge distances between the electrodes, CH₄/CO₂ ratio and flow rate on the reaction are investigated. The optimal discharge parameters of the reaction are achieved. Experiment results and comparison with other plasmas indicate the warm plasma has the advantage of low energy consumption.
