发明名称 Selective dealumination of MOR type zeolites
摘要 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.

主权项 1. A method for the selective dealumination of the aluminum within the 12-membered ring channels of a zeolite of structure type MOR, which method comprises the steps: (i) loading a MOR zeolite in the hydrogen or aluminum form with a univalent metal to obtain a metal loaded zeolite, wherein the MOR zeolite is loaded with the univalent metal to exchange all or substantially all of the Brønsted acid sites in the 8-membered ring channels but not the Brønsted acid sites in the 12-membered ring channels; (ii) treating the metal loaded zeolite with steam at a temperature of at least 400° C. to obtain a metal loaded dealuminated zeolite.
