✦ Synopsis

Adsorption and desorption of gaseous adsorbate into a bidisperse structured sorbent is investigated theoretically in this paper. A general model is developed and using a perturbation analysis six independent degenerate models are derived. The criteria of validity of these degenerate models are delineated and this will help readers to choose the proper model for their systems. The explicit expressions for the half-times for adsorption and desorption are also derived. This will provide readers a quick means to calculate the time scale of their process.
