This project develop pressurized chemical looping (PCL) using ceria (CeO₂) to enable efficient syngas and hydrogen production under industrially relevant conditions. Our approach leverages ceria’s reversible redox cycle, where lattice oxygen is released and replenished to drive gas conversion in a controlled, cyclic manner. We combine experimental measurements with kinetics-based reactor modeling to capture rate-limiting behavior during cycling, and embed the validated kinetics into system-level simulations to quantify mass/energy balances and compression/heat-integration requirements. This integrated framework provides design guidance for scalable deployment of PCL in high-temperature industrial environments.
