Zinc-substituted zeolite adsorbents and processes for the use thereof in gas separation

摘要

Monovalent and/or divalent cation-exchanged zeolite adsorbents, such as zinc-substituted zeolites, for use in separating nitrogen from a gas, such as air, and a process for use of the adsorbents in a PSA cycle to economically and effectively produce nitrogen from air.
