摘要：
Mesoporous structures of porous carbonaceous adsorbents have been characterized in terms of the fractal dimension. It has been shown that for these solids the fractal dimensions D lie between 2.6 and 3.0. The lowest value of D has been obtained for the SAO carbon black, whereas for the RIG, RIB and PA carbons the D-values reached the upper limit. The fractal dimension D was evaluated from the benzene adsorption isotherms measured gravimetrically at 293 K. It has been shown that these isotherms are useful for estimating the surface irregularity of porous carbons.
