Abstract

The production of hydrogen by the decomposition of pure methane and methane/steam mixtures in a microwave -irradiated fixed bed reactor packed with devolatilized coal char was studied. Input power levels from 600–3500 W were used. Low conversions were obtained for pure methane as the feed, but 1:1 molar ratio mixtures of methane and steam gave high conversions. The effects of power level and feed flow rate were determined for the methane/steam case. Additionally, microwave heating and conventional heating were compared for the methane/steam case. Microwave heating was found to require temperatures 3050 °C lower to give the same methane conversions obtained with conventional heating, over a conversion range of 18-53%. Thus, it may be concluded that microwave heating promotes the methane/steam reaction in some type of unique manner.
