NOTE
Surface Fractal Parallel Plate Models for Micropore Structures of Active Carbon fractal surface is allowed to be placed out of the periphery of its neighbors under the conditions that k/10 parts of the S n surface in terms of surface In order to analyze the micropore structures of active carbon, area are placed in the x ΓΊ 0 region on the x-y coordinates and that the two types of surface fractal parallel plate models are calculated. remaining (10 0 k)/10 parts of the S n surface are in x Γ΅ 0 on the same It is shown that the disordered model, in which fractal surfaces coordinates, where the randomly sampled k is 0, 1, 2, . . . , 10. After 100,000 are less restrictively piled up in the horizontal direction compared structure units are constructed, the pore size distribution is calculated using with the ordered one, can simulate the micropore size distribution the same method as for the ordered parallel model. of active carbon.
