摘要
开发新型高效的二氧化碳捕集或利用技术对于减少化石能源利用过程的二氧化碳排放、缓解全球变暖等具有重要意义。集成二氧化碳捕集与利用技术(ICCU)因其能耗低和效率高等优势获得了广泛关注。该技术利用一种双功能材料通过集成二氧化碳吸附和原位转化两个主要过程,实现CO_(2)的高效转化并获得含碳燃料。本工作综述了ICCU中主要技术之一集成二氧化碳捕集与甲烷化转化。首先对实现该过程的双功能材料的组成和特性进行概述,重点从反应温度、反应时间、反应气体成分等角度探讨了影响ICCU甲烷化反应的因素,并对该技术未来的机遇和挑战进行总结和展望,以期为中国“双碳”目标下致力于二氧化碳捕集和利用的相关研究提供一定的借鉴。
The development of novel carbon dioxide capture or utilization technology is of great significance to reduce carbon dioxide emissions from fossil energy utilization, as well as to alleviate global warming. The integrated carbon dioxide capture and utilization(ICCU) technology, which integrate carbon dioxide adsorption and in-situ conversion to realize efficient conversion of carbon dioxide to carbon containing fuels over dual function material, has attracted extensive attentions due to its advantages of low energy consumption and high efficiency. In this paper, the composition and characteristics of the dual function materials for CO_(2) capture and methanation were summarized. The factors which affected the methanation process were discussed from the perspectives of reaction temperature, reaction time, feed gas compositions. The challenges and opportunities in the near future were also proposed.
