Abstract
It is suggested that the nonhomogenity of the microporous structures of carbonaceous adsorbents should be expressed through the normal distribution of the micropore volume by sizes (halfwidth for the slitlike model). On the basis of the theory of the volume filling of micropores in vapor adsorption, a new Dubinin-Stoeckli adsorption equation is obtained. Its three parameters—the total volume of the micropores, their halfwidth for the maximum of the distribution curve, and dispersion—are identical to the parameters of normal distribution. This is true only when the initial vapor adsorption isotherm has been corrected for adsorption in mesopores. Then the parameters of the adsorption and distribution equations, which are determined from the experimental vapor adsorption isotherm, are real quantities. It is shown that the most rational method for determining the mesopore specific surface area necessary for correcting the isotherm is the Dubinin-Kadlec γ F method identical to the t F method. The concepts developed are experimentally substantiated.
