Enhancing the Activity of Iron Based Oxygen Carrier via Surface Controlled Preparation for Lignite Chemical Looping Combustion†

doi:10.7503/cjcu20140756

Abstract

Abstract:

We selected Fe₂O₃ as the model oxygen carrier for chemical looping combustion(CLC) to theoretically detect the electronic properties of the high index surface(104) and the referenced low index surface(001). Fe₂O₃(104) exhibits better electronic structure for the interaction to lignite. Then, based on the theoretical calculations, Fe₂O₃(104) supported on Al₂O₃ was obtained via surface-controlled preparation. The reaction between lignite and the prepared Fe₂O₃(104)/Al₂O₃ is more efficient than the reaction between lignite and the reference Fe₂O₃/Al₂O₃ prepared via traditional impregnation method, which corresponds to the theoretical calculations. Ultimate analysis shows less carbon deposit on the reduced Fe₂O₃(104)/Al₂O₃ than on the reduced Fe₂O₃/Al₂O₃. Further, the fresh and the regenerated oxygen carrier were characterized, which verified the regeneration ability of Fe₂O₃(104) after severe structural relaxation during the reaction processes. These findings indicate that morphological control of oxygen carrier is very rewarding and will throw light to the next generation of highly efficient oxygen carriers for CLC technology.
