Abstract

Dry autothermal reforming (DATR) from methane-carbon dioxide-air mixtures under different thermal management concepts was investigated in this study. The thermal management schemes included without porous medium (PM) assisted catalyst packed-bed, PM assisted, and PM assisted with thermal insulation. Controlled parameters included CO2/CH4 ratio, O2/CH4 ratio, and thermal management concepts. The experimental results demonstrated that the internal heat recirculation (PM assisted) could be enhanced reforming gas temperature, thereby improved the methane and CO2 conversion, syngas yield, and reforming efficiency. The best reforming parameters for thermal management design were a methane flow rate of 10 L/min, CO2/CH4 molar ratio of 1.0 and an O2/CH4 molar ratio of 0.8, achieving a reforming efficiency of up to 80.65%. The prediction was calculated using the commercialized HSC Chemistry software (&ChemSW Software, Inc.). Good correlation was obtained between the experimental and the calculation results.
