Notes: The adsorption and effective diffusivity of pyridine dissolved in heptane were measured in silica-alumina pellets using a specially developed single-pellet continous-flow diffusion cell. The measured diffusivities varied between 0.43 × 10-9 and 3.25 × 10-9 m2·s-1; the temperature dependence of the diffusivities indicated that both pore volume diffusion and surface diffusion play a role in the mass transfer.
