To be realistic, diffusion in bidisperse porous structures is often considered in terms of macropore diffusion and micropore diffusion. In this approach the diffusivity and the mass balance are defined separately for each pore system. Ruckenstein et al. (1971) and many investigators (Haynes and Sarm
