The technology of chemical looping air separation, with the characteristics of simple operation, low cost, and low energy consumption, separates oxygen from air with the oxygen carrier. In this work, reaction properties of monolithic oxygen carriers were investigated in a fixed-bed apparatus, with the consideration of the reactor temperature, oxygen concentration, and reaction gas flow. The XRD results showed that active phase, Al₂O₃, and cordierite cannot react with each other in calcination processing. The SEM results showed that the micromorphology of oxygen carrier was loaded on cordierite honeycomb uniformly with sphere or sphere-like particles. Oxygen carriers show a faster oxygen release rate and a slower oxygen intake rate. With increasing of absorption temperature, oxygen concentration of inlet gas, and desorption temperature, the reaction rate per unit mass increases. With increasing of gas flow rate, the reaction rate per unit mass decreases. The maximum value of the reaction rate per unit mass was obtained by Y_0.95Ti_0.05BaCo₄O_7+δ monolith sample. Samples substituted with Dy element showed fine performance of stability, as Dy substitution causes more serious local lattice distortions.

化学循环空气分离技术，具有操作简单、成本低、能耗低的特点，利用氧载体将氧气从空气中分离出来。在这项工作中，在固定床装置中研究了整体式氧载体的反应特性，同时考虑了反应器温度、氧气浓度和反应气体流量。XRD结果表明活性相Al ₂ O ₃, 和堇青石在煅烧过程中不能相互反应。扫描电镜结果表明，氧载体的微观形貌均匀地负载在堇青石蜂窝上，呈球状或类球状颗粒。氧载体表现出更快的氧气释放速率和更慢的氧气摄入速率。随着吸收温度、入口气体氧气浓度和解吸温度的升高，单位质量的反应速率增加。随着气体流量的增加，单位质量的反应速率降低。Y _0.95 Ti _0.05 BaCo ₄ O _{7+ δ}得到单位质量反应速率的最大值整体样品。用Dy元素替代的样品表现出良好的稳定性，因为Dy替代导致更严重的局部晶格畸变。
