Use of lithium-containing fau in air separation processes including water and/or carbon dioxide removal |
摘要 |
A process for separating a feed gas into at least one product gas includes: (a) providing a gas separation apparatus with at least one adsorption layer including a lithium-exchanged FAU adsorbent having water desorption characteristics, defined by drying curves, similar to those for the corresponding fully sodium-exchanged FAU, a heat of adsorption for carbon dioxide equal to or lower than that for the corresponding fully sodium-exchanged FAU at high loadings of carbon dioxide, and onto which the adsorption layer water and/or carbon dioxide adsorb; (b) feeding into the gas separation apparatus a feed gas including nitrogen, oxygen, and at least one of water and carbon dioxide; and (c) collecting from a product end of the gas separation apparatus at least one product gas containing oxygen.
