Abstract: The Cu-based oxygen carriers were prepared by mechanical mixing method. The effects of reaction temperature, gas flow, the type and the fraction of inert carriers on the oxidation and reduction reactivity of Cu-based oxygen carriers were investigated in a fixed bed reactor. The results show that with the increasing of reaction temperature, the reduction reactivity decreases whereas the oxidation reactivity increases. However, when the gas flow increases, both oxidation and reduction reactivity increase. For the three kinds of oxygen carriers with different inert carriers, the oxidation reactivity is slight different, but the reduction reactivity has a striking contrast and the order of reduction reactivity is Cu/Mg>Cu/Zr>Cu/Si.Both oxidation and reduction reactivity increase with the increasing fraction of inert carriers.

Key words: chemical looping oxygen production, fixed bed reactor, Cu-based oxygen carrier, oxidation reactivity, reduction reactivity
