Beyond Parabolic Concentration Profile inside Porous Solids

EasyChair Preprint no. 4145

4 pagesDate: September 7, 2020


We discuss a new way to approximate the concentration profile inside the porous solids. It is an extension of the work of Liaw et al., who adopted a parabola (i.e., quadratic) profile, which is a function of pellet radius, while retaining the spherical symmetry. We extend their work by adding the quartic term. The inclusion of this new term still preserves the form of linear driving force approximation with some correction to Glueckauf's parameter. The presence of such a correction will affect the breakthrough curve, although its significance can only be determined experimentally. We plan to apply the result to the case of fixed-bed adsorber used for hydrogen/methane separation with activated carbon.

Keyphrases: activated carbon, Glueckauf's parameter, Hydrogen, Linear driving force, methane
