Abstract
Oxyfuel combustion process, in which oxygen with high purity is fed to the boiler for combustion, and a major part of the CO 2- rich exhaust gas is recycled back to the boiler to maintain the combustion temperature, can simplify flue gas treatment resulting potentially in a zero CO 2 emission to the atmosphere. The key to the success of the oxyfuel process is the cost-effective production of oxygen. In this work, perovskite-like compound YBaCo 4O 7 (YBC114) and perovskite-type SrCo 0.8Fe 0.2O 3-δ (SCF82) have been prepared and used to produce O 2-enriched CO 2 stream for oxyfuel combustion. Results show that YBC114 has a big potential for the production of O 2-enriched CO 2 stream at a low temperature, and SCF82 can be used to produce high-temperature O 2-CO 2 gas mixture for oxyfuel combustion.
