Mechanism of Methane Chemical Looping Combustion Using Fe2O3 Promoted with CeO2

This study demonstrates the CeO₂ promoted Fe₂O₃ oxygen carrier suitable for the CH₄ CLC process. Fixed bed tests show addition of 5 wt% CeO₂ improves reactivity and capacity of Fe₂O₃ producing almost twice as much CO₂ per-unit time compared to the sum of CO₂ when the oxides are tested separately.
