TWO COMPONENT SYSTEM ION EXCHANGE X TYPE ZEOLITE ADSORBENT

摘要

The present invention involves an improved adsorbent for gas separation processes. The adsorbent comprises a binary ion exchanged Type X zeolite wherein between 5% and 40% of the available ion sites are occupied by Ca, and between 60% and 95% of the available ion sites are occupied by Sr. The present adsorbent is especially useful for the adsorption of N2 from an air stream at superambient pressure to produce an O2-rich product stream.
