摘　　要：在“双碳”背景下,化学链制氢是一种可替代传统制氢的新方案,具有经济高效等特点。选择合适的载氧体对工艺的稳定性能至关重要,这些载氧体具有高反应性、选择性、材料强度和抗烧结性等性能。综述了目前常用的化学链工艺流程,包括双反应器与三反应器,并对几种不同的金属载氧体性能进行了比较,同时总结了不同载氧体反应机理。由于载氧体在反应过程中出现结焦和团聚等现象,因此众多研究者关注如何从微观层面有效地避免这些问题。最后,对载氧体作为可再生、可持续和环境友好型材料的前景进行了展望。Based on the background of'dual carbon',the chemical chain hydrogen production process is a novel alternative to traditional hydrogen production schemes,with economic and efficient characteristics.Choosing appropriate oxygen carriers is crucial for the stability of the process,as they require high reactivity,selectivity,material strength,and sintering resistance.This article provides an overview of commonly used chemical chain processes,including dual reactors and triple reactors,and compares the performance of several different metal oxygen carriers in depth.At the same time,summarizing the reaction mechanisms of different oxygen carriers is helpful for selecting appropriate oxygen carriers in the process.Due to the phenomenon of coking and agglomeration of oxygen carriers during the reaction process,numerous researchers have paid significant attention to its avoidance at the micro level.Finally,the prospects of the oxygen carrier used as a renewable,sustainable and environmentally friendly material are prospected.
