Abstract: This study explores the applicability of the adsorption-diffusion mechanism to describe the transport of binary "methanol-water" and "ethanol-water" mixtures in pervaporation through a commercial microporous silica membrane. Two different adsorption-diffusion models are considered: one based on Fick's diffusion equation and another based on the Maxwell-Stefan formulation. Basic models (Fick) assume concentration independent parameters; more complex models (Maxwell-Stefan) incorporate flux coupling and other non-idealities.
