In this study, the iron-based oxygen carrier was used for the syngas production via chemical looping dry reforming of methane (CL-DRM). The effect of the content of F2O3 supported by Al2O3 on the reduction stage during the CL-DRM was examined for various reaction temperatures was experimentally studied. It was found that higher Fe2O3 content and reaction temperature were required to obtain high CH4 and CO2 conversions and avoid carbon deposition. The experimental results indicated that 100% CH4 and CO2 conversion can be obtained from 30wt% Fe2O3 oxygen carrier and reaction temperature of 1000°C. At lower Fe2O3 contents and temperatures, Fe2O3 has low reactivity and high carbon deposition leading to poor CL-DRM performance. The experimental results also indicated that iron-based oxygen carrier was suitable for reducing CO2 into CO and carbon.
