Abstract

A model for analyzing the process of impregnation (and, in a sense, the inverse process of extraction) for a porous solid with two types of pores is considered that is suitable for describing the process at large values of time. A solution to the problem with the most typical additional conditions is obtained, and the kinetic function of impregnation (extraction) and the flux density of a substance from a solid are found. A set of equations of the problem is reduced to a single equation. The issues associated with the applicability of this equation and the possibility of its generalization are discussed.
