Abstract
The modelling of gaseous diffusion and sorption in bidispersed solid sorbents is examined with a view to account for the through-flux in the microphase -a feature missing in prior treatments but known to be of experimental significance. In the modification proposed here, the micropores, having widely varying diffusivities, are divided into two groups with one group controlling sorption time and the other providing the through-flux. The various control regimes of the model are discussed, and the model is found to satisfactorily interpret experimental data on the adsorption/desorption of SO2 on activated carbon.
