直接空气捕集CO_(2)吸附剂综述

Review of CO_(2) direct air capture adsorbents

综述直接空气捕集CO_(2)吸附剂的研究进展,对比碱/碱土金属基吸附剂、金属有机框架吸附剂、负载胺基吸附剂、变湿吸附剂的优缺点,从吸附容量与胺效率、动力学与载体选择、再生方式与能耗、热稳定性与抗降解等方面对吸附剂性能进行评估.简要叙述相关工程示范项目和技术经济性;总结研究中存在的问题,展望未来的研究方向.

The research progress of direct air capture CO_(2) adsorbents was reviewed.The advantages and disadvantages of alkali/alkaline metal based adsorbents,metal organic framework adsorbents,amine loaded adsorbents and moisture swing adsorbents were compared.Meanwhile,the properties of adsorbents from the aspects of adsorption capacity and amine efficiency,kinetics and supporters,regeneration mode and energy consumption,thermal stability and resistance to degradation were evaluated.Additionally,the related engineering demonstration projects and economic evaluation were briefly discussed.Finally,the problems existing in the current research were summarized,and the future research direction was prospected.
