Abstract The technology of removing CO2 from coal-fired power plants by sodium-based sorbents has received increasing attention. However, the researches on sodium-based sorbents both with high CO2 capture capacity and attrition resistance are still insufficient, which hindering the industrial applications of the sodium-based sorbent. This paper is devoted to solve this problem. Different elements, including Zr2+, Mg2+ and Ca2+, were separately doped in the sorbent and the corresponding CO2 sorption and attrition resistance performances were studied. Under the desired doping content (1–15 wt%), Zr2+, Mg2+ and Ca2+ improved the mechanical strength of the sorbent with the order of Zr2+

在 CO2 吸附/解吸过程中具有高耐磨性和 CO2 捕获能力的元素掺杂钠基吸附剂

摘要 钠基吸附剂脱除燃煤电厂CO2的技术越来越受到重视。然而，对兼具高CO2捕集能力和耐磨耗性的钠基吸附剂的研究还不够，阻碍了钠基吸附剂的工业化应用。这篇论文就是专门用来解决这个问题的。不同的元素，包括Zr2+、Mg2+和Ca2+，分别掺杂在吸附剂中，并研究了相应的CO2吸附和耐磨性能。在所需的掺杂含量（1-15 wt%）下，Zr2+、Mg2+ 和 Ca2+ 以 Zr2+ 的顺序提高了吸附剂的机械强度
