Abstract:
Hydrogen-rich synthesis gas produced by the sorption enhanced gasification (SEG) of biomass is suitable not only for heat and power generation but also for biofuel and chemical production. A challenge of SEG for synthesis gas production is its relatively high methane content with a high calorific value. This methane has the potential to become a source of synthesis gas and energy. Non-catalytic partial oxidation of methane in the simulated SEG-derived synthesis gas was thus examined in this study. Such a method can produce useful gases like H2, CO, and CO2 for synthesis applications while also providing energy to the reforming unit. The effects of main parameters on the product composition and energy released, such as preheating temperature, steam to methane ratio, and oxygen to fuel ratio, were investigated. In addition, the role of hydrogen in methane oxidation was addressed. This study found that the presence of hydrogen in the reactants enabled an ignition to take place at a lower preheating temperature. Steam could be used to modify the composition of the product gas. With a high oxygen to fuel ratio, a high methane conversion was achieved.
