摘要/Abstract

摘要： 以机械混合法制备的铜基载氧体为研究对象，在固定床反应器中研究了反应温度、气体流量、惰性载体种类和惰性载体添加比例对铜基载氧体吸放氧性能的影响.实验结果表明:随着反应温度的升高载氧体的吸氧性能降低，但放氧性能提高；载氧体的吸放氧性能都随气体流量的增大而提高；对于制备的三种不同惰性载体的载氧体，其吸氧性能相差不大，放氧性能为Cu/Mg> Cu/Zr> Cu/Si.对于制备的三种不同惰性载体添加比例的载氧体，其吸放氧性能均随惰性载体添加比例的增大而提高.

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
