ABSTRACT
Generalization was made on the basis of the lattice-gas model, the ideas of which are used twice: to describe the structure of a complex porous system, and to account for intermolecular interactions in the quasichemical approximation. The basis of calculation of the structure of a complex system is the procedure for separating model areas of the porous system with a simple regular geometry of predetermined length, and also including junctions for various types of porous areas. The complex porous structures can be used to model a variety of types of porous systems from zeolites cavities approximated by spheres with a relatively short length of the cylindrical parts of different diameter, to modelling junctions of long cylindrical portions in new mesoporous materials. Spherocylindrical systems consist of two types of elements of the free volume of pores having a finite extent, when the pore system is formed by alternating cylinders and truncated spheres.
