Intraparticle forced convection is a mechanism of mass transport in “large-pore” materials used as catalysts, adsorbents, HPLC packings, ceramic membranes and supports for mammalian cell culture and biomass growth. The particle-level problem for catalysts which considers diffusion, convection and reaction in isothermal situations is revisited. Extension is made for nonisothermal catalysts in order to get a priori estimation of the maximum temperature inside the catalyst and effectiveness factor. The analysis of effective diffusivity measurements in large-pore supports by chromatographic techniques is reviewed. It is shown how the relation between “apparent” effective diffusivity [image omitted] and “true” effective diffusivity De[image omitted], i.e., De/De = 1/(A) helps in understanding the behavior of large-pore supports in adsorptive separation processes. |
