The model of an adsorption bed is described in which the effect of axial dispersion and overall adsorption kinetics on a shape of the breakthrough curve is considered simultaneously. Separation of the effects of convection and axial dispersion from the effect of overall kinetics was achieved applying the method of statistical moments. On the basis of relations derived for the moments, several further characteristics of the breakthrough curves were expressed.
