Dry Reforming of Methane Using a Swirl-Induced Plasma Discharge Reactor

This study reports the dry reforming of methane (DRM) using non-thermal plasma in a swirl-induced point-plane electrode discharge reactor to produce syngas. geometry facilitates better mixing reactant gases region, thus increasing residence time and conversion reactants. The effect varying flow rates compositions CO2/CH4 (v%/v%) on was studied. A high-voltage AC power input 50 W 70 at frequency 19 kHz provided. voltage–current characteristics with respect were results show that an increase rate gas mixture from 0.5 2 LPM both CO2 CH4 decreases, while concentration or (from 25 75%) increases respective reactant. products, viz. syngas (CO H2), C2 hydrocarbons, solid carbon, characterized quantified. maximum total 44% obtained for CO2:CH4 ratio 25:75 LPM. carbon collected walls analyzed, it found be 89.9% pure traces oxygen functionality. decreased specific energy input, which eventually resulted lowering cost.
