Investigation of the adsorption in zeolites at zero filling
The experimental determination of the thermodynamic characteristics of adsorption (TCA) at low filling and at different temperatures is considered. The data for a few reference systems (low alkanes in types X and Y zeolites) have been used to improve the atom—ion potentials of molecule—zeolite intermolecular interaction. The possibility of using these potentials in the molecular statistical calculations of TCA of other alkanes and nonstrained çyclanes has been investigated. For polar molecules the point moment approximation has been additionally used. Quadrupole moment of cyclopropane was calculated by the chromatoscopic method.
