Nonuniform microporous structures and adsorption properties of carbonaceous adsorbents. 10. The question of the sizes of the micropores of carbonaceous adsorbents

Conclusions

• 1. The linear regression method proposed by McEnaney for the comparative analysis of studies reported in the literature of the sizes of the micropores of carbonaceous adsorbents obtained by small-angle x-ray scattering and measurements of the heats of immersion in liquid of adsorbent of different size micropores made it possible to establish that there is good correspondence between the two methods.

• 2. The ratio between the half-width of the micropores x₀ and the characteristic energy of adsorption E₀ of standard benzene vapor used in the theory of volume pore filling is evaluated. In the range of micropore half-widths from 0.4 to 1.5 nm, the maximum deviation of x₀E₀=12.0 nm·kJ/mole does not exceed 10%.
