PROGRESS IN EFFECTS OF EXTA- FRAMEWORK CATION OF ZEOLITES ON N2/O2 ADSORPTION CHARACTERISTIC

A Review on the recent study of zeolite molecule sieve, such as LSX, Li-Zeilites, Ca2+- Zeilites and LiAgX, based on the significance of adsorbents for oxygen production of air separation in pressure swing adsorption (PSA), is presented from dsorption properties. The relations between zeolite adsorption characteristic and zeolite framework, the locations and quantities and species of exta- framework cation are analyzed. Applications of zeolite adsoebents for air separation in PSA are also prospected.
