Abstract

� 2017 Methane and carbon dioxide are two major components in many biomass-derived gases such as landfill gas and biogas, which are renewable and have potential fuel cell applications. Syngas production from non-catalytic and fuel-rich combustion using a two-layer porous media burner was studied experimentally and numerically with a range of CO2content in the CH4fuel. With an air flow rate of 5�L/min, an equivalence ratio of 1.5 and a mole ratio of CO2/CH4of 1, the reforming efficiency was found to be 45.3%, larger than that (39.1%) without CO2in the feed at the same air flow rate and equivalence ratio. A two-dimensional model with an elementary reaction mechanism was developed to study the influence of carbon dioxide on the reforming characteristics. The model is validated by the experimental results with good agreement. The simulation results clearly showed that the reaction process along the burner could be divided into a preheating zone, a CO2-consuming zone and a CO2-generating zone according to the net reaction rate of CO2.
