Cover illustration. Li‐LSX zeolite is the sorbent of choice for air separation via pressure swing adsorption (PSA). Due to the rapidly rising Li cost, it is desirable to minimize Li use. Li cations occupy Sites I' and II (SI' and SII) preferentially, and only cations on SIII are used for adsorption. Mixed LiCa‐LSX with only a few %Li show better PSA performance compared to Ca‐LSX and only slightly lower performance than pure Li‐LSX.

封面插图。Li‐LSX沸石是通过变压吸附（PSA）进行空气分离的首选吸附剂。由于锂成本的快速上升，因此希望使锂的使用最小化。锂阳离子优先占据位置I'和II（SI'和SII），并且仅使用SIII上的阳离子进行吸附。与Ca‐LSX相比，仅含少量Li的混合LiCa‐LSX表现出更好的PSA性能，并且仅比纯Li‐LSX略低。图片由密歇根大学富兰克林·埃皮邦（Franklin Epiepang）编辑。10.1002 / aic.16032
