Conclusions
-
1.
It has been established experimentally that at 740 K and ∼90 MPa, approximately three molecules of N2 or O2 are adsorbed in a small cavity of NaA zeolite.
-
2.
Analysis of the desorption curves indicates that for CsNaA zeolite (degree of exchange of Na+ by Cs+ 70%) it is impossible to distinguish quantitatively between adsorption in the large and the small cavities.
