The technology of circulating fluidized beds (CFBs) is applied to temperature swing adsorption (TSA) processes for post‐combustion CO₂ capture employing a commercial zeolite sorbent. Steady state operation is simulated through a one‐dimensional model, which combines binary adsorption with the CFB dynamics. Both single step and multi‐step arrangements are investigated. Extensive sensitivity analyses are performed varying the operating conditions, in order to assess the influence of the main operational parameters. The results reveal a neat superiority of multi‐step configurations over the standard one, in terms of both separation performance and efficiency. Compared to fixed‐bed TSA systems, CFB TSA features a high compactness degree. However, product purity levels are limited compared to the best performing fixed‐bed processes, and heat management within the system appears to be a major issue. As regards energy efficiency, CFB systems place themselves in between the most established absorption‐based technologies and the fixed‐bed TSA. © 2017 The Authors AIChE Journal published by Wiley Periodicals, Inc. on behalf of American Institute of Chemical Engineers AIChE J, 64: 1744–1759, 2018

循环流化床系统建模，用于通过变温吸附来燃烧后捕集二氧化碳

循环流化床（CFBs）技术应用于燃烧后CO _2的变温吸附（TSA）工艺使用商业沸石吸附剂进行捕集。通过一维模型模拟稳态运行，该模型将二元吸附与CFB动力学相结合。研究了单步和多步布置。为了评估主要操作参数的影响，在不同的操作条件下进行了广泛的灵敏度分析。结果表明，在分离性能和效率方面，多步配置均比标准配置更具优势。与固定床TSA系统相比，CFB TSA具有很高的紧凑度。但是，与最佳性能的固定床工艺相比，产品纯度水平受到限制，并且系统内的热量管理似乎是一个主要问题。关于能源效率，CFB系统处于最成熟的基于吸收的技术和固定床TSA之间。©2017 Wiley Periodicals，Inc.代表美国化学工程师学会出版的《作者AIChE期刊》AIChE J，64：1744–1759，2018
