Carbon dioxide (CO) emissions from fossil fuel combustion have been linked to increased average global temperatures, a global challenge for many decades. Mitigating CO concentration in the atmosphere is a priority for the protection of the environment. This is a comparison of the three main technological categories available for CO capture and storage. They include: oxy-fuel combustion, pre-combustion, and post-combustion. Each capture technology has inherent benefits and disadvantages in cost, implementation, and flexibility, but post-combustion CO capture has demonstrated the most promising results in typical power plant configurations. This paper presents a review of different post-combustion CO capture materials; solvents, membranes, and adsorbents, focusing on economical and environmentally safe low to high temperature solid adsorbents. Furthermore, the authors summarize the advantages and limitations of the materials investigated to provide insight into the challenges and opportunities currently facing the development of post-combustion CO capture technologies. The solid sorbents currently available for CO capture are also reviewed in detail, including physical and chemical properties, reactions, and current research efforts on improvement.
化石燃料燃烧产生的二氧化碳（CO₂）排放与全球平均气温上升有关，这是几十年来的一个全球性挑战。降低大气中的二氧化碳浓度是环境保护的首要任务。本文比较了三种主要的二氧化碳捕集与封存技术类别。它们包括：富氧燃烧、燃烧前捕集和燃烧后捕集。每种捕集技术在成本、实施和灵活性方面都有其固有的优点和缺点，但燃烧后二氧化碳捕集在典型的电厂配置中已显示出最有前景的结果。本文综述了不同的燃烧后二氧化碳捕集材料；溶剂、膜和吸附剂，重点关注经济且环境安全的低温至高温固体吸附剂。此外，作者总结了所研究材料的优点和局限性，以深入了解燃烧后二氧化碳捕集技术目前面临的挑战和机遇。还详细综述了目前可用于二氧化碳捕集的固体吸附剂，包括其物理和化学性质、反应以及当前的改进研究工作。
