Correlation between initial heats of adsorption and structural parameters of molecular sieves with different chemical composition—a calorimetric study

Abstract

Calorimetric measurements of the differential molar adsorption heat of nonpolar molecules onto molecular sieves reveal that the initial adsorption heats - increase linearly with the molar aluminium fraction of the adsorbents, which have the same crystal structure but different chemical composition and also - increase with the framework density of the adsorbents, which have the same chemical composition but different crystal structure. © 1993 IUPAC
