Abstract
Provided is a novel synthesis technique for producing pure phase small pore zeolites employing a synthesis gel of at least one zeolite, a structure directing agent and an alkaline earth metal source. Additionally provided are a novel form of AFX zeolite, a novel synthesis method for producing a zeolite with an increased Al pair content, a catalyst comprising the AFX zeolite in combination with a metal, and methods of using the same.
Claims5
A method for making an aluminosilicate zeolite having a small pore framework comprising reacting a synthesis gel comprising at least one zeolite, a structure directing agent, an alkaline earth metal source, and an optional silica source at a temperature of at least about 100° C. until crystals of the small pore zeolite form.
