利用氢能替代常规化石能源是运输行业应对气候变化和环境污染问题的一个重要突破口。将化学链技术应用于制氢过程不仅可以提高能量转换效率、减少环境污染，还可以在制氢的同时捕捉该过程产生的CO2，具有广阔的发展前景。本文概述了化学链制氢的两种方式的原理及特点，总结了不同过程在载氧体的筛选、反应器的形式以及系统模拟方面的研究现状。指出高效载氧体的筛选和制备是各个过程成功运行的关键。化学链水蒸气重整制氢[CLR(s)]过程需要考虑管束的磨损问题，而自热化学链重整制氢[CLR(a)]过程需要注意过程中的反应热量平衡。廉价载氧体的筛选、固体燃料的化学链制氢及其系统开发是化学链制氢(CLH)过程未来研究方向。

Application of renewable fuel,especially hydrogen,is an efficient way to fight against the climate change and reduce the emission of the pollutants from the transport sector. Hydrogen production using chemical looping technology is a potential method for hydrogen production,which not only can improve energy conversion efficiency and reduce environmental pollution,but also can separate carbon dioxide,which shows good economic efficiency and promising future. This paper introduces two different approaches to produce hydrogen using chemical looping technology. The present development statuses on the screening of oxygen carrier particles,the design of proper reactors,and the system simulation for each approach are summarized respectively. The screening and preparation of proper oxygen carriers is the basis of successful operation in each process. The potential erosion of the reformer tubes by the oxygen carriers in CLR(s) process and the heat balance between the FR and AR in CLR(a) process need to be considered. The development of oxygen carriers with low price,and the design of proper reactor and the coupled system for solid fuel will be the main focus of CLH study.
