Structure And Activity

60wt%Fe2O3/Al2O3oxygen carriers were prepared by different methods and characterized by means of XRD, H2-TPR, infrared gas analyzer. The effects of preparation methods on the structure and activity of Fe2O3/Al2O3oxygen carriers for chemical looping combustion of methane were also investigated. The factors on the selectivity of CO2in the chemical looping combustion process at different reaction temperatures were discussed. Methane can be quickly converted to CO2and H2O with high selectivity at 850°C for 15 min. After redox cycling in alternant methane/air atmosphere for 30 times, the formation of CO2was enhanced, indicating higher activity of oxygen carrier after the redox experiment.
