Abstract
Calorimetric measurements of the differential molar adsorption heat of nonpolar molecules onto molecular sieves reveal that the initial adso rption heats increase linearly with the molar aluminium fraction of th e adsorbents, which have the same crystal structure but different chem ical composition and also increase with the framework density of the a dsorbents, which have the same chemical composition but different crys tal structure.
