论文摘要
讨论了在南极洲直接捕获Co $ _2 $的直接空气捕获的可能性。由于南极冬季在大气中的H $ _2 $ O的浓度极低,因此直接空气捕获的装置可以采用基于物理吸附的过程,因此原则上允许非常短的吸附/解吸周期时间。较低所需的绑定允许更多的吸附剂材料选择。随着周期时间较短的时间,可以花费更多的资源来构造吸附剂以提高能源效率,例如,如果取消吸收是热驱动的,则可以提高其质量效率。
The possibility of direct air capture of CO$_2$ in Antarctica is discussed. Because the concentration of H$_2$O in the atmosphere during the Antarctic winter is extremely low, an installation for direct air capture could employ a physisorption-based process, allowing, in principle, a very short adsorption/desorption cycle time. The lower required binding allows more options for materials for the sorbent. With a shorter cycle time, more resource could be spent on structuring the sorbent to improve energy efficiency, for example by improving its mass efficiency if desorption is driven thermally.
