Research progress on carbon dioxide capture technology based on electric swing adsorption

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. © 2023 Chemical Industry Press.
