Gas Dispersion Coefficients in First-Order Adsorption Packed Beds

Abstract

With concentration of the adsorbing gaseous species assumed to possess radial symmetry in the spherical solid adsorbent particle, the dispersion coefficient of the gas flowing in the adsorbent packed bed is investigated theoretically. The result showed that the dispersion coefficient was identical with that under inert condition. Experimental measurements made with nitrogen-spherical activated carbon also verified the theory.
