On the dispersion of characteristic geometric sizes of porous structure ofactivated carbon in examined production batch.

Granulated activated carbon of A type purchased from HPSDD was elutriated i nto eight fractions of different internal structure. Benzene vapour adsorpt ion-desorption isotherms were determined at 293 K. The dispersions of chara cteristic geometric sizes were evaluated on the basis of analysis of these isotherms. The volumes of meso- and micropores, geometric surface areas and linear size of slit-like micropores were analysed. The fractal analysis le ads to the estimation of the fractal dimension and its dissipation in exami ned production batch of activated carbon. Obtained results lead to new corr elation between fractal dimension and average size of fractal structure.
