摘要：
We report adsorption and spectroscopic measurements for mixtures involving low molecular weight hydrocarbons (methane, propane, isobutane) and carbon dioxide and also for pure methane; where possible, comparisons with molecular simulation are made. AlPO4-5 and VPI-5 were found to selectively adsorb isobutane in isobutane/CO2 gas mixtures and propane in propane/methane gas mixtures, while little or no selectivity was observed for isobutane in isobutane/propane on AlPO4-5. In-situ diffuse reflectance infrared spectroscopy has been used to study the adsorbate-adsorbent and adsorbate-adsorbate interactions of trace gases on VPI-5. This provided an insight into the extents of adsorption and strengths of the intermolecular adsorbate-adsorbent interactions.
