CONNECTIVITY OF HETEROGENEOUS POROUS STRUCTURES AND CATALYTIC DEACTIVATION

A more realistic representation of heterogeneous porous structures and its applications to the phenomenon of catalytic deactivation under ki netic control conditions is considered. Pore space is considered as a correlated network of voids (sites) interconnected by necks (bonds) fo llowing the so-called construction principle. Percolation theory is us ed to show that the connectivity of the pore space is a fundamental co ncept for understanding the catalytic behavior. Results for different types of porous structures are presented.
