Abstract: CeO2-Fe2O3/LaNiO3 was prepared by citric acid complexation method and immersion method, and was used as the oxygen carrier in chemical looping hydrogen generation. The experiment was conducted under the conditions: ratio of Fe2O3 to CH4 of 2:1, water 0.1 mL, and atmospheric pressure to investigate the effect of reaction temperature. The results show that H2 output increases first and then decreases with increasing Fe loading. The optimum loading of Fe is 15%; Addition of CeO2 improves the stability of the oxygen carrier. Under the condition of atmospheric pressure, ratio of Fe2O3 to CH4 of 2,0.1 mL of water, reduction and oxidation reaction temperature of 800 ℃, the 5%CeO2-15%Fe2O3/LaNiO3 oxygen carrier can be repeatedly used for 100 times with high activity.
