Abstract
Bulk, Knudsen and surface diffusion of multicomponent mixtures inside porous media are described in a consistent manner using the Maxwell - Stefan formulation. By using several practical examples it is demonstrated that the simple Fick formulation is generally inadequate for the description of intraparticle diffusion because it can fail even at a qualitative level to describe the observed phenomena.
