Binary Mixtures of Chlorobenzene and Cyclohexane Vapours Adsorbed under Dynamic and Static Conditions by Activated Carbon Beds

Abstract

ABSTRACT:The adsorption of mixtures of chlorobenzene (C 6 H 5 Cl) + cyclohexane (c-C 6 H 12 ) onto activated carbon U-03 has been examined at about room temperature. As shown by Stoeckli et al. (2002), combination of the Myers-Prausnitz-Dubinin theory (MPD) with the activity coefficients of the corresponding solid-liquid equilibrium led to a good correlation between the calculated and experimental mole fractions for the adsorption of binary mixture vapours by microporous solids under static conditions. The present study demonstrates the approach, which is based on an ideal adsorbed state (IAS).This can be employed for binary vapour mixtures such as chlorobenzene + cyclohexane under dynamic conditions in PSA (Pressure Swing Adsorption) and dynamic breakthrough experiments.
