摘要:

基于变电吸附的碳捕集技术,通过“通电-断电”实现摆荡模式,利用电能焦耳效应产生热能,驱动吸附剂实现连续地吸附与再生。相对于变温吸附,其输入高品位电能,因此可驱动碳源、碳汇之间的大浓度差富集,近年来备受关注。然而,目前限制变电吸附碳捕集技术应用的主要问题是较高的能耗与较低的产率。据此,本文总结了近年来国内外变电吸附碳捕集技术的研究进展并提出了技术展望。首先讨论了变电吸附碳捕集的基本原理,其次综述了近十年变电吸附碳捕集技术中吸附剂、循环结构的研究进展及发展趋势,应用热力学第二定律效率对变电吸附碳捕集系统展开评价。最后,对变电吸附碳捕集技术发展趋势进行展望,变电吸附技术具备规模化竞争力的关键为:在改善吸附剂导电和捕集性能的基础上,改进吸附剂制备工艺,关注吸附剂的加热形式以及吸附腔体内的电阻分配,尝试与其他碳捕集技术耦合进行分级捕集,与可再生能源进行集成。

Abstract:

The carbon capture based on electric swing adsorption (ESA) could achieve a swing cycle through on/off mode of power. Meanwhile, it employs Joule heating effect of electrical energy to generate heat and hence to drive the continuous adsorption and regeneration of the adsorbent. With the input of electrical energy in high-grade, an enrichment for a significant concentration difference between carbon source and sink could be achieved, leading to its recent widespread attention. However, the main challenges currently limiting the application of ESA for carbon capture are high energy consumption and low generation efficiency. This paper provided a literature review on research progress on ESA for carbon capture. Firstly, the fundamental principles of carbon capture technology using ESA were presented. Secondly, the research progress and development trends of adsorbents and cyclic construction of ESA for carbon capture over the past decade were reviewed. The performance evaluation of ESA for carbon capture was conducted through the second law of thermodynamics efficiency. Finally, the future development trends of carbon capture technology using ESA were discussed. The key to competitive scalability of such technology lied in improving the conductivity and capture performance of the adsorbent. The preparation technology of adsorbent should be improved. Attention should be given to the heating form of the adsorbent and the resistance distribution in the adsorption chamber. Additionally, coupling with other carbon capture technologies for hierarchical capture should be considered and integration with renewable energy sources should be explored.

Key words: CO2 capture, adsorbents, desorption, electric swing adsorption, cycle structure, analysis of performance, thermodynamics
