    摘要:

    钙基材料因吸收二氧化碳容量高、制备工艺简单和钙循环等特点被认为是最具应用前景的高温碳捕集材料之一。将钙基固废作为或构筑钙基吸收剂不仅可节约天然资源,同时可实现工业固废的资源化利用,符合“以废治废、以废冶污”的环保理念。首先,通过Huntzinger和热力学理论分析了工业常见的六种钙基固废的理论固碳潜能。其次,分类综述了这些废渣直接碳化及制备衍生钙基材料的方法及存在的问题和改进方向,并总结了钙基材料提升吸收能力的各种方法及提升机制。最后,从气体扩散、离子迁移和吸附剂结构稳定性角度出发说明了钙循环的实质,提出氧空位和中空球体结构在提升吸附性能方面具有较大的潜力,指出了工业钙基固废实现工业化应用面临的问题及改进方向。

    Abstract:

    Calcium-based material has been considered as a most promising high-temperature carbon capture material due to its high carbon dioxide absorption capacity, simple preparation process, and calcium cycling characteristics. Using calcium-based solid wastes as or constructing calcium-based adsorbents can not only save natural resources, but also achieve the utilization of industrial solid wastes, which is accordant with environmental protection concepts of “treating waste with waste and treating pollution with waste”. Firstly, the theoretical carbon sequestration potential of six common industrial calcium-based solid wastes was analyzed using Huntzinger and thermodynamics. Secondly, the methods for direct carbonization of these waste residues and the preparation of derived calcium-based adsorbents, as well as the existing problems and improvement directions, were classified and summarized. Various methods and mechanisms for improving the uptake capacity of calcium-based adsorbents were also summarized. Finally, the essence of calcium cycling was explained from the perspectives of gas diffusion, ion migration, and adsorbent’ structure stability. It was pointed out that oxygen vacancies and hollow sphere structures have great potential in improving adsorption performance, and the problems and improvement directions faced by industrial calcium-based solid waste in industrial application were pointed out.
