Chemical-looping combustion (CLC) of methane was carried out in an annular shape fluidized bed reactor with double circulations. Combustion efficiency of the continuous and semi-continuous operations with NiO and Fe2O3 supported on bentonite were determined. Combustion efficiencies of the semi-continuous operations with NiO/bentonite and Fe2O3/bentonite are over 99 % in both cases, and those of the continuous operations are around 97 % and 72 %, respectively. The chemical reactivity of NiO is higher than Fe2O3 in the CLC process. The concentration of CO in flue gas was below 1% and no H2 emission was detected.
