摘要：
The size and geometry of oxygen carriers are one of the key factors to determine the efficiency of a large-scale chemical looping combustion (CLC) system in fixed bed reactors, because they strongly affect the dynamic conditions of the gas-solid reactions, such as the intra particle mass transfer limitation for reactants, the pressure drop and the flow distribution. In the present work, we describe for the first time the utilization of bulk monolithic oxygen carriers for chemical looping combustion of methane in a fixed bed reactor. The comparison on the structure and reactivity of the monolithic Ce-Zr-Fe-O/Al2O3 oxygen carrier with the powder one is investigated in detail. The successive CH4-reduction/air-oxidation redox testing of the monolithic oxygen carrier is also performed. It is found that the Ce-Zr-Fe-O/Al2O3 oxygen carriers own high activity for methane complete oxidation due to the strong active component
