摘要：

Cu, Co, Mn and Ni decorated Fe2O3/Al2O3 oxygen carriers were prepared by freeze-drying method in this work. Temperature programmed reduction (H2-TPR) and Temperature programmed oxidation (TPO) experiments were conducted in an automatic chemisorption instrument, and the reactivity of transition metal decorated Fe2O3/Al2O3 oxygen carriers with H2 and O2 was evaluated. The results showed that the reactivity for oxygen carrier with H2 was improved after decorated with Cu, Co and Ni. But when decorated with Mn, the reactivity and oxygen transport capacity of oxygen carrier decreased. The Cu-decorated Fe2O3/Al2O3 oxygen carrier demonstrated the best reactivity with H2 and favorable stability. Therefore, it could be a potential oxygen carrier for using in the chemical looping combustion. ©, 2015, Science Press. All right reserved.
