Reduction kinetics of SrFeO/CaO∙MnO nanocomposite as effective oxygen carrier for chemical looping partial

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 12,   Pages 1726-1734 doi: 10.1007/s11705-022-2188-5

Abstract: Chemical looping reforming of methane is a novel and effective approach to convert methane to syngas,In this work, the kinetics of SrFeO3−δ–CaO∙MnO nanocomposite reduction by methane wasDuring the methane reduction, combustion occurs before the partial oxidation and there exists a transitionThe proposed rate law could well predict the reduction kinetics; thus, it may be used to design and/oranalyze a chemical looping reforming reactor.
