Amore realistic representation of heterogeneous porous structures and its applications to the phenomenon of catalytic deactivation under kinetic control conditions is considered. Pore space is considered as a correlated network of voids (sites) interconnected by necks (bonds) following the so-called construction principle. Percolation theory is used to show that the connectivity of the pore space is a fundamental concept for understanding the catalytic behavior. Results for different types of porous structures are presented.
