Catalytic Tri-reforming of Methane Using Flue Gas from Fossil Fuel-based Power Plants

Equilibrium properties of tri-reforming under different conditions were analyzed by thermodynamics. Although both CO₂ and steam conversions decreased with O₂ concentrations in the tri-reforming system, steam conversions decreased more dramatically than CO₂ conversions. CO₂ showed higher equilibrium conversions (87 and 53.1%, respectively) than the steam conversions (77 and 26.7%, respectively). To achieve higher CO₂ conversions in catalytic tri-reforming of the methane, a tailored catalyst for tri-reforming was desired.
