Abstract: The measured equilibrium data of n-heptane adsorption on molecular sieve were tested according to the Dubinin and Langmuir equations of adsorption isotherms. The deviations from Langmuir concept were evaluated by means of equilibrium function. The applicability of Dubinin equations was examined graphically. The cause of deviations from Dubinin equations was investigated by using characteristic curves. The differential isosteric heats of adsorption as well as entropy of adsorption were calculated. The latter was correlated with the translation contribution to gaseous adsorbate entropy.
