  • Adsorption, flows in porous and granular materials




The paper contains a proposition of a model of adsorption in porous, and granular materials. It is assumed that the mass source resulting from adsorption consists of two contributions: an equilibrium phase change described by the Langmuir isotherm, and a nonequilibrium change due to the relaxation of porosity. The model is illustrated by a simple numerical example of a homogeneous adsorption process.
