چکیده:

To develop an adsorption separation technology, researches on the adsorption mechanism are necessary
in both theory and experiment. Many researchers have achieved great successes in describing adsorption
behavior by different methods models. In this work, experimental adsorption isotherms of pure oxygen and
nitrogen as well as their mixtures have been obtained with a volumetric method on zeolite 5A. Pure and
binary data are given at temperatures of 273,283, 303, and 343 K and in pressure range 0.05-10 bar. Several
EOS were used for modeling the collected data. The model utilizes the 2-D van der Waals, Soave-Redlich-
Kwong, Peng-Robinson and Eyring equation of state with a classical mixing rule to predict the total
adsorption for the pure and binary systems. Model constants in the 2-D EOS are determined from pure
adsorption equilibrium data and then used to predict adsorption of binary mixtures. The predictions are
compared with experimental data. Comparison of the results from the experiments and the thermodynamic
modeling gave a reasonable agreement.
