Abstract：

Chemical looping combustion is one of the most important technologies to deal with climate change in China.As the carrier of oxygen and heat,oxygen carrier is the key factor to realize chemical looping combustion.In recent years,how to develop cheap oxygen carriers has become a major concern.Due to its advantages of low cost,abundant resources,environmental friendliness and good mechanical properties,Fe-based oxygen carrier has attracted extensive attention,but its reactivity is relatively poor,and how to improve its reactivity is the key to its large-scale application. In this paper,the research progress on the improvement of the activity of Fe-based oxygen carrierin chemical looping combustion was reviewed.In order to improve the reactivity of Fe-based oxygen carrier,the optimization of preparation method,the doping of components and the structure regulation of Fe-based oxygen carrier were discussed.It is pointed out that the preparation method of oxygen carrier should be further improved by combing the factors such as the reaction performance,the preparation duration and cost of oxygen carrier.For the oxygen carrier components,the addition of the inert carrier,preparation of the composite oxygen carrier and alkali metal doping can improve the reactivity of the oxygen carrier to some extent.However,there are certain problems in the use of a single measure,such as the interaction of the active component with the inert carrier,the sintering of the composite oxygen carrier,and the loss of the alkali metal.Therefore,it is necessary to further study the interaction among various factors.For the oxygen carrier with different structures,it has good structural stability or thermal stability,but it also has its own disadvantages.For example,the oxygen carrier with perovskite structure has low oxygen storage capacity and oxygen release ability.The oxygen carrier with spinel structure may be deactivated by crystal phase separation and particle sintering during a long cycle.The oxygen carrier with core-shell structure,shell materials need to be further optimized so as to maintain its stability and reactivity in the cycle.Based on the current research status,it is pointed out that further improvement of the Fe-based oxygen carrier reactivity needs to comprehensively consider various factors and deeply explore the interaction between various factors.
