Description
Summary:The microporous phase of carbonaceous materials is characterized by means of fractal dimension D, determined on the principle of the coverage of microporous body of ideal shape with a monolayer of molecules of various sizes. A part of molecules remains lying on the external surface of the solid phase characterizing it with the dimension D=2 and another part enters into the micropores (with dimension D=3) respecting their size distribution. The combination of both dimensions gives the resulting value of fractal dimension within interval 2< D
