Abstract:
In this paper was studied adsorption of diethyl ether from the gas phase on two zeolites, mordenite (NaM) and H-form mordenite (HM), under 5000 Pa pressure and 300 K temperature. Adsorption study was experimentally examined by volumetric method. Adsorption of diethyl ether on NaM and HM in this pressure range fit to adsorption isotherm Type III, which describes weak interactions between adsorbate and adsorbent. Classic interpretation of adsorption isotherm Type III is weak adsorbate-adsorbent interaction and low adsorption at relative lower pressure, but when the molecules of adsorbate are adsorbed, those interactions help through adsorption of other molecules of adsorbate. Adsorpiton increases with increasing the relative pressure. It was found that, under the experimental conditions in this study, HM has higher adsorption capacity than NaM. Those differences in adsorption capacity are the consequences of different specific areas and sthrenght of active sites of these two zeolites. Experimental data for both adsorbents are fitted due to Freundlich isotherm model.
