为了减少与最先进的碳捕获技术相关的能源惩罚和成本，正在开发一系列第二代和第三代二氧化碳捕获技术。其中一种技术基于固体吸附剂，用于碳捕获中的气体分离，有可能显著减少能源惩罚，并避免与当前技术相关的一些问题。然而，要实现这一潜力，需要两个主要的发展：新的多孔材料和新的植物集成工艺。本应用笔记描述了与该应用的功能材料开发相关的性能要求和挑战。我们描述了材料开发的主要挑战，以及使固体吸附剂成为可行的大规模二氧化碳捕获过程所需的操作条件、气体成分、稳定性和寿命方面的要求。还讨论了潜在的未来研究和目前正在开发的突破性材料的例子。
In an effort to reduce the energy penalty and cost associated with state-of-the-art carbon capture technologies, a range of 2nd and 3rd generation CO2 capture technologies are being developed. One of these technologies, based on solid sorbents for the gas separation in carbon capture, has the potential to significantly reduce the energy penalty and avoid some of the problems associated with the current technologies. However to realise this potential, two main developments are required: new porous materials and new plant integration processes. This application note describes the performance requirements and challenges associated with the development of functional materials for this application. We describe the key challenges for materials development and the requirements in terms of operating conditions, gas composition, stability, and lifetime to make solid sorbents a viable large scale CO2 capture process. Examples of potential future research and breakthrough materials currently being developed are also discussed.
