化学链燃烧技术是一种新颖的二氧化碳分离技术,其中金属载氧体持续循环反应能力的优劣直接关系到该技术的实际应用和推广。以Ni基和Co基金属载氧体为研究对象,用热重分析仪(TGA)、扫描电镜(SEM)和X射线衍射仪(XRD)等工具研究了二者的持续循环能力。结果表明,添加惰性载体后载氧体的反应速率和持续循环能力均有大幅的提升,且Ni基载氧体比Co基载氧体表现出更好的反应特性和持续循环能力。 Chemical chain combustion technology is a novel carbon dioxide separation technology, in which metal oxygen carrier cycle of continuous merits the merits of the direct related to the practical application of the technology and promotion. Taking Ni-based and Co-based metal oxygen carriers as the research objects, the continuous cycling capability of the two was studied by means of TGA, SEM and XRD. The results show that the reaction rate and the continuous cycle capacity of the oxygen carrier increase greatly after adding the inert carrier, and the Ni-based carrier oxygen exhibits better reaction characteristics and continuous cycling ability than the Co-based carrier.
