Abstract

In this paper

the material balance equation on fixed bed adsorption col-umn was simplified by neglecting the longitudinal dispersion effect. The parameters of adsorption and transfer were estimated by transfer function method on pulse-response experiments. The adsorption equilibrium constants and overall mass transfer coefficients of C8 aromatic isomers obtained from the experiments were agreed with the breakthrough curves of adsorption and desorption.
