Research Progress of Nonmetal Oxide Oxygen Carriers in Chemical Looping Combustion

简述化学链燃烧技术是一种能实现CO_2内分离、提高燃烧效率的燃烧技术及钙基载氧体具有更高的氧传递能力、价格低廉、环境友好的特性,介绍非金属载氧体CaSO_4不同实验测试与表征手段的研究现状,分析认为串行流化床非常适合于非金属载氧体CaSO_4化学链燃烧技术的应用,并提出未来的研究方向。

Chemical looping combustion（CLC）is a very promising technology combined with the potential of reducing the costs and energy penalty dramatically for CO2 capture.Compared with metal oxides,CaSO4 has a relatively higher oxygen capacity.CaSO4 is much cheaper and environmentally sound as a nonmetal oxide oxygen carrier.Therefore,CaSO4 applied to CLC has a very broad range of applications.According to the different test and characterization methods,the present study situation of nonmetal oxide oxygen carrier was introduced in detail and interconnected fluidized bed was very suitable for the application of nonmetal oxide oxygen carrier in chemical looping combustion,and finally the future study direction was pointed out.
