Redox Property of the Supported Fe 2 O 3 and WO 3 with TPO/TPR

The three-reactor chemical-looping process (TRCL) for the production of hydrogen from natural gas is attractive for both capture and hydrogen production. In this study, redox property of and supported with and were studied with temperature programmed oxidation/reduction (TPO/R) experiment. All metal oxides were prepared by ball mill method. Metal oxides supported with showed the good redox property in TPO and TPR tests. Reduction behavior was matched well the theoretical reduction mechanism. Metal oxides supported with formed a solid solution (, ). showed more narrow reaction range and lower reaction temperature than .
