Porous Structure of Activated Carbon Fibers

Abstract

The dependence of the microporous structure of activated carbon fibers on the carbonization temperature of hydrate-cellulose fibers was studied by BET, TVFMP, and Horvath and Kawazoe techniques and methods of the nonlocal density functional theory. The surface energy distribution function was obtained, together with the micropore size distribution curves. It was shown that the effective micropore sizes calculated by the TVFMP method are close to the maximum of the distribution function found in terms of the theory of the density functional.

Characterization of the porous structure of carbon adsorbents with a wide size distribution of micropores

“…Based on the shape of the adsorption isotherm, they provide direct information about the size distribution of pore volumes. Examples of such calculations for activated carbon adsorbents were given in [5][6][7][8] and showed that the NDFT method is quite informative.…”
