✦ Synopsis

A simple lumped model is presented based on the assumption that a linear driving force approximation is valid in describing the surface diffusion within adsorbent particles. The Freundlich-type multicomponent isotherm and the ideal adsorbed solution (IAS) theory were incorporated with the model to deal with competitive adsorption. Model parameters were easily estimated from correlations and obtained by conducting single-component hatch experiments. The major advantage of this model is that it does not require much computation time unlike the diffusion models. The model presented can be used satisfactorily in predicting breakthrough curves for two-component simultaneous and counter-current adsorptions of phenols on activated carbon in fixed beds.

The technique based upon the constant pattern model was extended to evaluate mass transfer coefficients for multicomponent (binary) adsorption by carbons. The mass transfer coefficient of the lesser adsorbed component was essentially the same for both single component and binary systems. The mass tr

## Abstract The problem of multicomponent liquid phase adsorption in fixed beds was studied further. In contrast to the earlier work (Hsieh et al., 1977), the method developed in this work is more efficient and also has a greater scope of applicability as it incorporates the use of the IAS (Ideal A
