摘　　要：为缓解温室效应带来的一系列严重的环境问题,亟需对主要的温室气体二氧化碳(CO_(2))进行减排。CO_(2)的捕集、利用与封存(CCUS)技术作为可以有效进行碳减排,得到了广泛应用。在CO_(2)捕集技术中,物理吸附分离技术具有能耗低、产品气质量稳定和适应性强等优点,可推广至不同工业应用场景。介绍了3种吸附分离技术的CO_(2)捕集场景:燃烧后烟气捕集、天然气净化以及直接空气捕集,以及可用于吸附分离技术的4种CO_(2)吸附材料:多孔碳材料、沸石分子筛、硅基材料与金属有机骨架材料,并对以上材料的适用条件与场景进行了总结,最后对CO_(2)吸附剂未来的发展方向进行了展望。In order to alleviate a series of serious environmental problems caused by greenhouse effect,it is urgent to reduce the main greenhouse gas,carbon dioxide(CO_(2))emissions.CO_(2) capture,utilization and storage(CCUS)technology has been widely used as an effective method to reduce carbon emissions.Among CO_(2) capture technologies,physical adsorption separation technology has the advantages of low energy consumption,stable product gas quality and strong adaptability,and can be extended to different industrial application scenarios.Three CO_(2) capture scenarios for adsorption and separation technologies:post-combustion flue gas capture,natural gas purification and direct air capture,and four kinds of CO_(2) adsorbent materials:porous carbon materials,zeolite molecular sieves,silicon-based materials and metal-organic framework materials were introduced.The applicable conditions and scenarios of the above materials were summarized,and the future development direction of CO_(2) adsorbents was prospected.
