Conclusions

  1. 1.

    The Na form of zeolites with a faujasite structure possesses a homogeneous adsorption field.

  2. 2.

    In the exchange of Na+ ions for Ca2+, primarily the cations situated in the six-membered oxygen bridges are exchanged. After the appearance of Ca2+ ions on the walls of the cavities, an increase in the initial heats of adsorption of benzene is observed.

  3. 3.

    The reduced heats of adsorption of benzene on Ca forms of synthetic faujasites are associated with the appearance in them of centers free of metal cations.

  4. 4.

    On decationized type Y zeolite, the heat of adsorption of benzene is lower than on the cationic forms and does not depend upon the filling.
