Conclusions
-
1.
A simple model in which adhering and interpenetrating carbon crystallites form a series of micropore zones is proposed for use in discussing pore systems in carbon adsorbents.
-
2.
Finite-dimensional micropores are formed by burn-off of crystallite carbon atoms in the course of gas-phase oxidative activation (intracrystalline micropores) and by the development of interstices between adhering crystallites (intercrystalline micropores).
-
3.
The model micropore zone is assumed to have the form of a small cube. The fissure interstices between faces of these cubes, or micropore zones, represent the micropore volume, and the total wall surface area of these pores the mesopore surface area. Calculation of the values of the parameters of such micropore structures from minimal experimental data is illustrated for various actual adsorbents.
-
4.
The attempt is made to model the structures of micropore zones and estimate the values of their parameters.
