Abstract
A model for percolative correlated networks of sites and bonds is used in the calculation of catalytic deactivation and the adsorption-desor ption hysteresis in porous materials. This model takes into account th e important characteristics of porous materials such as correlations b etween voids and throats (sites and bonds). Experimental data on catal ytic deactivation by coke formation and nitrogen sorption on alumina s ustrates are analyzed and compared with model predictions.
