化学链工艺中金属载氧体的研究进展OA

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.
