Adsorption microcalorimetry of non-polar argon and quadrupolar nitrogen gases was carried out at 77 K and 302 K on two chemically different faujasite type zeolites (DAY and NaX). Considering absolute quantities adsorbed, the differential enthalpies of adsorption at zero coverage obtained with each system do not vary with temperature. Similarities in the differential enthalpies with increasing coverage...
The adsorption of non polar (argon, methane) and quadrupolar (carbon dioxide, nitrogen) gases on siliceous Faujasite at ambient temperature and high pressure conditions up to 50 bar, is investigated both experimentally and theoretically by combining Microcalorimetry and Grand Canonical Monte Carlo techniques. The aim of this present work is to evaluate the adsorption isotherms as well as the evolution...
Isotherms, differential enthalpies of adsorption and Henry’s constants were obtained for nitrogen at 300 K on CaX, BaX, SrX and MnX faujasite systems. The experimental data are compared with those obtained by Monte Carlo simulations based on newly derived force fields for describing the interactions between the extra-framework cations and the adsorbates. It is the first time that such good qualitative...
