摘要
本文讨论了在南极进行二氧化碳直接空气捕集的可能性。由于南极冬季大气中 HO 的浓度极低，直接空气捕集装置可采用基于物理吸附的工艺，原则上允许极短的吸附/解吸循环时间。较低所需的结合能可为吸附剂材料提供更多选择。凭借更短的循环时间，可将更多资源用于吸附剂的结构设计以提高能效，例如若解吸由热驱动则可改善其质量效率。

备注
This paper is built around a hypothesis that a one-second adsorption/desorption cycle time is possible. A justification for this hypothesis is not provided, and without it this paper should not be used as a basis for further work. I have been working to describe how such a cycle time might be achieved, and find that it is a difficult problem. This paper was posted prematurely
