要旨

Due to the complex, often sponge-like structure of monolithic adsorbents it is diffcult to define appropriate constituent units that characterize the hydrodynamics of the material, or to determine relevant shape and size distribution factors comparable to those for spherical particles in (particulate) fixed beds. Based on a phenomenological analysis to the friction factor (Reynolds number relation and the longitudinal dispersivity - Peclet number dependence for random sphere packings) we derive characteristic lengths (i. e., equivalent particle dimensions) for a monolith with regard to its hydraulic permeability and dispersion originating in stagnant zones. Equivalence to the hydrodynamic behavior in "reference" sphere packings is established by dimensionless scaling of the respective data for the monolithic structure. This phenomenological apprach, which is simply based on liquid flow and stagnation in a porous medium, can successfully relate hydrodynamic properties of the monolith to that of particulate beds. © 2002 WILEY-VCH Verlag GmbH, Weinheim, Fed.
