摘要：

The influence of water on acidity and catalytic performances of zeolites has been widely studied and controversial results have been proposed in literature. The re-hydration of zeolite Beta is here evaluated as a tool to recover the Bronsted acidity, that can be partially lost during thermal treatments (e.g. regeneration). Introduction of controlled amounts of water influences both the Al siting and the acidity distribution in zeolite Beta and consequently the density of the active sites.
