  • Selective dealumination of MOR type zeolites
    Patent number: 8956588
    Abstract: Method for the selective dealumination of the aluminum within the 12-membered ring channels of a zeolite of structure type MOR. The method includes the steps of (i) loading a MOR zeolite in the hydrogen or ammonium form with a univalent metal to obtain a metal loaded zeolite; and (ii) treating the metal loaded zeolite with steam at a temperature of at least 400° C. to obtain a metal loaded dealuminated zeolite.
