摘要(Abstract)：

为推动“双碳”战略，促进工业固废兰炭灰的低成本消纳，开发新型绿色低碳复合材料，提出在已有的兰炭灰/硝酸钠复合相变储热材料基础上，利用兰炭灰进行碳捕捉。对固碳前、后兰炭灰及复合相变储热材料的性能进行研究。结果表明：兰炭灰碳捕集的最佳条件为气体组分20%CO_2/80%N_2、通气时间40 min、加热温度650℃；在最佳实验条件下，兰炭灰的固碳率达到29.27%，所制得的复合相变储热材料固碳兰炭灰/NaNO_3的最佳质量比为5:5，在100～380℃储热密度达到288.65 J/g，拥有更好的机械性能、热稳定性及化学相容性。固碳兰炭灰作为骨架材料制备复合相变储热材料具有较好的可行性，为工业固废兰炭灰的资源化利用和碳排放处理提供了新的途径。
