Abstract:
The adsorption capacity of O2 and N2 on a LTA-type zeolite can be significantly affected by the change of its Si/Al ratio. With the increase in Si/Al ratio and the decrease in the amount of Na+, the protonated high-silica LTA zeolite changes from being a N2-selective sorbent to an O2-selective sorbent to reverse the O2 and N2 selectivity.
