Adsorption in a porous solid having a bimodal pore size distribution has been investigated theoretically using an n-th order approximation suggested by Do and Mayfield (1987). For the two physical systems involving bimodal adsorbents, a single particle and a batch adsorber, the new model solution shows remarkable agreement with the exact solution. The classical linear driving force model (LDF) has also been considered; it is found that this model is inferior to the new model suggested by Do and Mayfield.
