Abstract: The invention relates to CeO2 and La2O3 for catalyzing Fe2O3—Al2O3 based chemical-looping reforming of CH4 with CO2 (CL-DRM). The reaction performance of all the composite oxygen carriers was evaluated in a fixed-bed reactor at atmospheric pressure condition. The influencing factors, including temperature and time-on-stream (TOS) were investigated. The characteristics of the oxygen carriers were checked with Brunauer-Emmett-Teller (BET) analysis and X-ray diffraction (XRD). The reducibility of the composite materials was elucidated with temperature-programmed reduction by CH4 (CH4-TPR). Preliminary experimental observations suggest that the simultaneous presence of CeO2 and La2O3 can not only enhance the reactivity of Fe2O3—Al2O3 toward CH4 oxidation and its oxygen releasing rate for fast reaction kinetics, but also improve the reactivity of its reduced form toward CO2 splitting.
