R. Krishna et Ja. Wesselingh, REVIEW ARTICLE NUMBER 50 - THE MAXWELL-STEFAN APPROACH TO MASS-TRANSFER, Chemical Engineering Science, 52(6), 1997, pp. 861-911
The limitations of the Fick's law for describing diffusion are discuss
ed. It is argued that the Maxwell-Stefan formulation provides the most
general, and convenient, approach for describing mass transport which
takes proper account of thermodynamic non-idealities and influence of
external force fields. Furthermore, the Maxwell-Stefan approach can b
e extended to handle diffusion in macro- and microporous catalysts, ad
sorbents and membranes. (C) 1997 Elsevier Science Ltd.
