Zeolites form an important class of inorganic materials with an enormo
us industrial interest which derives from their molecular sieving, ion
-exchange and catalytic properties. The research in this field now tak
es advantage on advanced modeling programs which allow us to examine i
n details the structure of these complex materials and their interacti
ons with adsorbed species both under static or dynamic conditions. The
information obtained is often fundamental for better understanding of
the mechanism of formation of these materials and their shape selecti
ve properties. In this paper, selected applications of modeling in zeo
lite science are presented and discussed. (C) 1998 Elsevier Science B.
