Abstract

Liquid adsorption in fixed bed was studied at room temperature for the binary system

para-xylene and ethylbenzene

with two types of zeolites- one prepared by our group

and the other imported. The mathematical model included a mass transfer equation involving the total mass transfer coefficient

and the equilibrium and the mass balance equations. These three equations were integrated numerically. The predicted breakthrough curves was close to the experimental. To explore further the mechanism of mass transfer

three models-liquid-phase controlling

solid-phase controlling and both-phase controlling were examined. The results showed that the solid-phase controlling model is the most appropriate for a system studied.
