Abstract: Material balances of a countercurrent adsorption column are given. Their transformation into a dimensionless form yields a set of dimensionless parameters which are suitable for a description of adsorption dynamics in both continuous and fixed beds. The necessity to introduce further dimensionless parameters characterizing the shape of equilibrium curve in dimensionless coordinates is proved. A general method is introduced which enables us to deduce these parameters from the equation of adsorption isotherm. The equations of equilibrium curves corresponding to the adsorption isotherms of Freundlich, Dubinin for the first and second structural type of sorbent, Langmuir, and B.E.T are presented.
