Modelisation of isothermal diffusion of steam on activated alumina
Written by sctunisie no commentsDiffusion 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.
