Abstract

We report on an adsorption study on two shale samples that have previously been investigated by small-angle neutron scattering (SANS). The scattering data indicate that these samples can be characterized as surface fractals in length from 5 Å to 500 Å, with the fractal dimension D between 2.83 and 2.75. Using the existing models for adsorption on fractal surfaces, the values of D deduced from the adsorption data appear to be consistently lower than the SANS results. We discuss these findings.

10. A proper fractal analysis should use only the adsorption branch of the isotherm above 40 torr. The reason that the desorption branch is not applicable is that on desorption the pores in the interior of the sample that satisfy Eq. (3) cannot empty until those on the outer part have emptied, so that they can have access to the surrounding vapor. This accessibility is not an issue on adsorption.Google Scholar
