Résumé
The kinetics of the adsorption of dichloromethane vapour by a typical active carbon have been measured at 288 and 323K and for spherical granules of 0.25 and 1.0 mm in diameter. The data have been analysed within the framework of a model for adsorption by bidispersed systems and under non-isothermal conditions. Micropore diffusion is the rate-controlling step, and direct measurements show that the process is not isothermal. However, thermal effects do not seem to influence significantly the kinetics of adsorption. Good agreement can be found between experimental and calculated data, and the model leads to micropore diffusivities and heat-transfer coefficients for the system under investigation.
