Development of Microwave-Matrix Partial Oxidation Reformer

This study proposes a novel microwave-matrix reformer (MMR) to convert biogas, a greenhouse gas that causes climate change, into high-quality fuel energy. To show its performance potential, it has identified the characteristics of biogas conversion and product gas for O 2 /C ratio, steam supply, reformed gas recirculation, and recirculated water supply, which affect CH 4 and CO 2 conversions. The reforming characteristics for different variables were achieved as follows. The optimal conditions of the MMR were 100% recirculation rate and 10 mL/min water supply when O 2 /C ratio and total gas supply were 1 and 30L/min, respectively. Under these conditions, CH 4 conversion was 68.6%, CO 2 conversion was 37.9%, H 2 selectivity was 88.1%, and H 2 /CO was 1.54, which were resonable for applying to stack for Solid Oxide Fuel Cell.
