文摘
- •
Effects of various B-site dopants for CaMnO3 based oxygen carrier are investigated.
- •
Fe-dopants can be effectively incorporated into the CaMnO3 structure.
- •
Fe-doped CaMnO3 samples show significant α-oxygen release between 350 and 500 °C.
- •
Fe-doped oxygen carriers observe long term redox stability without formation of undesired phases.
- •
Fe-doped CaMnO3 exhibits superior activity for Pittsburgh #8 coal char combustion compared to undoped samples.
