heal.abstract	A three-dimensional network model based on the structural characteristics of a random packing of equal spheres has been developed for the simulation of sorption and diffusion processes in mesoporous sorbents composed by non-porous spheroidal primary particles. The simulation provides satisfactory prediction of adsorption-desorption isotherms of carbon tetrachloride and pentane for different porosities, temperatures and adsorbates. The hysteresis of the desorption branch is estimated as a summation of thermodynamic or single pore hysteresis and the network hysteresis, The overall sorbed volume is calculated as the summation of the volume due to multilayer adsorption and that due to capillary condensation.
