Preparation of Metal Oxide-based Oxygen Carriers Supported with CeO2 and γ-Al2O3 for Chemical Looping Combustion

The development of efficient oxygen carriers (OCs) in chemical looping combustion (CLC) exhibited tremendous achievement considering inherent CO2 capture. The selectivity of CO2 in the CLC process depends on the performance of employed OCs during multiple redox cycles. Different types of OCs were pr...
