A mathematical model of fixed-bed and expanded-bed adsorption systems was presented. The model consists of two partial differential equations: the mass balance equation and the kinetics equation. Fluid dispersion for packed-bed and expanded-bed and solids mixing for expanded-bed were considered. To verify the model adsorption of phenol on granular activated carbon was examined. Model parameters: film transfer coefficient kf and dispersion coefficient DF were estimated. Using molar viscosity coefficient introduced by Kurgaev a satisfactory correlation of mass transfer factor Jd and modyfied Schmidt number Scwith modyfied Reynolds number Rewas established.
