Modelisation of isothermal diffusion of steam on activated alumina

Written by sctunisie no comments

Diffusion equation under conditions of diffusivity variation with concentration is solved numerically by Crank-Nicholson method. A simple exponential dependence of diffusion coefficient with concentration is assumed.Comparison of experiments with theory shows that the model describes the adsorption kinetics adequately and allows the knowledge of the diffusional coefficient parameter.
