Resumen:
In the present work we study how the adsorption-desorption hysteresis loop of a mesoporous-disordered
medium represented by a three-dimensional dual site-bond model is affected by percolation for different
kinds of site and bond distributions. The behavior of the threshold pressure for the evaporation process,
as a function of the separation between the site and bond distributions and their dispersions, suggests
a method to determine them from experimental adsorption-desorption hysteresis curves.
