| Description
| - Porous membrane supports and other porous media are in widespread use in many fields of chemical technology. The pore structure is inherently complex; therefore, many models of mass transport simply describe pore space as a continuum consistent with its appearance on a macroscopic scale. Besides the pore space complexity, a number of fluid phases determine the nature of mass transport. Even when a relatively simple case of single-phase transport of gases is considered, a variety of mass transport mechanisms, including ordinary, Knudsen and surface diffusion, and viscous flow, can occur in pore space. All continuum models of mass transport involve empirical factors that describe transport characteristics of the pore structure. Unfortunately, these empirical factors, such as tortuosity, an effective pore radius, and an effective square of pore radii, are constant only if steady transport of non-reactive gases is considered. For example, it is known that tortuosity depends on the rate of chemical reaction. On the other hand, random pore networks avoid the use of empirical factors and model the pore space as interconnected pores with random distribution of pore sizes. For determination of pore space geometry and topology, several experimental methods have been developed for the past fifteen years, e.g. stochastic reconstruction and X-ray computed microtomography.
