Review of Lithium Silicate Ceramic for High Temperature CO_2 Capture

CO2是造成全球气候变暖的主要因素,需要从排放源中直接捕获二氧化碳,然后进行储存,以有效地控制大气中的二氧化碳浓度。本文综述了硅酸锂陶瓷材料高温捕获烟气中二氧化碳的分离理论,硅酸锂陶瓷材料的制备方法,CO2高温捕获效率的影响因素,以及电厂CO2高温捕获工艺,并提出了硅酸锂陶瓷材料高温捕获CO2今后的发展方向和研究重点。

The greenhouse effect which is mainly caused by carbon dioxide has become a global concern. CO2 capture and storage （CCS） is an effective technology that enables the capture of CO2 from fuel combustion or industrial processes and its storage underground, thereby preventing it from entering the atmosphere. Recent research process on the capture of CO2 from high temperature flue gas by lithium silicate ceramic material is summarized, including the theory of CO2 capture, the preparation of lithium silicate ceramic materials, the factors affecting CO2 capture capacity, as well as the technological process of CO2 capture from high temperature flue gas. Furthermore, challenges and future work for the development of this field are proposed.
