Chemical-looping combustion (CLC) has been proposed as an efficient and clean technology that could contribute to achieve carbon dioxide capture with negligible cost. The technology uses a metal oxide as oxygen carrier that indirectly transfer oxygen from air to fuels so as to oxidize the fuels. This paper presents a new inorganic membrane Fe-based oxygen carrier prepared by mixing Fe2O3 and coal ash with certain proportion of corn starch (10.0 wt.%, 20.0 wt.%, and 30.0 wt.%). The structure of the prepared oxygen carrier was characterized by scanning electron microscope (SEM) and an X-ray diffractometer (XRD). The activity of the prepared oxygen carrier was measured by performing thermogravimetric analyzer (TGA) experiments and Temperature programmed desorption (TPD) experiments. Results show that the inorganic membrane Fe-based oxygen carrier has higher reduction reactivity and stability than the conventional oxygen carrier.
