Li+- and H+-Exchanged Low-Silica X Zeolite as Selective Nitrogen Adsorbent for Air Separation

Low-silica X zeolite, Ion-exchange, Selective nitrogen adsorption
Li+ and H+ co-exchanged LSXs (Li-H-LSX) with various ratios of Li+ and H+ were prepared, and those adsorption characteristics of nitrogen and oxygen were compared with Li-Na-LSX and Li-Ca-LSX. Li-H-LSX showed higher nitrogen capacity and selectivity than that of Li-Na-LSX in the wide range of Li-exchanged ratio. The nitrogen capacity of Li-Ca-LSX was slightly higher than that of fully Li- or Ca-exchanged LSX (Li- LSX or Ca-LSX). However, Li-Ca-LSX showed low nitrogen/oxygen adsorption selectivity until the Li content reached about 80%, which was a tendency near that of Ca-LSX.
