燃煤烟气排放的碳源被认为是全球CO2浓度快速上升的主要因素之一，为应对以CO2为主的温室气体大量排放所带来的气候环境问题，世界各国纷纷将低碳发展上升为国家战略。高温CO2捕集技术一直是碳减排领域的研究重点，CaO基和Li4SiO4基固体吸附剂是目前2种最常见也是最具应用前景的高温CO2吸附剂，吸附剂粉末造粒成型是其工业循环流化使用的必要前提。对CaO基和Li4SiO4基吸附剂的造粒成型技术进行了分析综述，主要通过造粒成型方式对CaO基和Li4SiO4基吸附剂进行分类总结和讨论，并对吸附剂颗粒化学吸附性能和机械强度方面的差异进行了分析。通过综述总结认为：机械成型法制备的CaO吸附剂颗粒通常具备更高的机械强度，但机械成型过程通常会对吸附剂原本的结构有一定的破坏，会造成吸附剂微观结构的密实化，从而影响CO2的化学吸附性能，而注模成型法制备的吸附剂颗粒其化学吸附性能较好，但由于没有机械力挤压的过程，其机械强度有待增强。针对Li4SiO4基高温吸附剂，由于可以避免直接成型过程造成的吸附剂颗粒破碎，间接成型法展现出了更大的造粒成型优势和应用前景。还对CaO基和Li4SiO4基吸附剂造粒成型的未来研究思路进行了探讨，以期对高温CO2固体吸附剂的发展和工业化应用提供助力。

Carbon source emitted by coal-fired flue gas is considered to be one of the main factors for the rapid rise of global CO2 concentration. In order to deal with the climate and environmental problems caused by the massive emission of CO2-based greenhouse gases, countries all over the world have raised low-carbon development as a national strategy.

High-temperature CO2 adsorbent capture technology has always been the focus of research in the field of carbon emission reduction and it is also one of the most direct and effective ways to achieve the "dual carbon" goal. CaO-and Li4SiO4-based solid adsorbents are currently the two most common and promising high-temperature CO2 adsorbents. The granulation of sorbent powder is a necessary prerequisite for its industrial circulating fluidization. This paper mainly analyzed and summarized the granulation and molding technology of CaO- and Li4SiO4-based sorbents. The CaO-and Li4SiO4-based adsorbents were classified, summarized and discussed mainly by granulation methods, and the differences in chemical adsorption performance and mechanical strength of sorbent particles were discussed and analyzed. It is concluded through the analysis that the CaO adsorbent particles  prepared by mechanical molding usually have higher mechanical strength, but have a certain damage to the original structure of the sorbent and leads to the densification of microstructures, thus affecting the chemical adsorption performance. The chemical adsorption performance of the adsorbent particles prepared by injection molding is better, but its mechanical strength needs to be enhanced because there is no mechanical extrusion process. For Li4SiO4-based high-temperature adsorbents, indirect molding method exhibits more advantages and application prospects because it can avoid the crushing of adsorbent particles caused by the direct granulation process. This paper also discussed the future ideas of granulation and molding of CaO-based and Li4SiO4-based adsorbents, in order to provide assistance for the development and industrial application of high-temperature CO2 sorbent.
