Abstract

Provided are a novel form of AEI zeolite, a novel synthesis technique for producing pure phase AEI zeolite, a catalyst comprising the AEI zeolite in combination with a metal, and methods of using the same. The AEI aluminosilicate zeolite has a cuboid morphology and a silica-to-alumina ratio of 20 to 50.

Claims (10)

1. An aluminosilicate zeolite comprising at least about 90% phase pure AEI framework, wherein the aluminosilicate zeolite has a cuboid morphology, wherein the aluminosilicate zeolite has a silica-to-alumina ratio of 20 to 50.

2. The aluminosilicate zeolite of claim 1 , wherein the aluminosilicate zeolite is substantially free of extra framework phosphorus.

3. The aluminosilicate zeolite of claim 1 , wherein the aluminosilicate zeolite has a mean crystal size of at, least about 100 urn.

4. The aluminosilicate zeolite of claim 1 , wherein the aluminosilicate zeolite has a D 90 crystal size of about 0.1 μm to about 7 μm.

5. The aluminosilicate zeolite of claim 1 , wherein the aluminosilicate zeolite comprises at least about 95% phase pure AEI framework.

6. The aluminosilicate zeolite of claim 1 , wherein the aluminosilicate zeolite is substantially free of medium and large pore frameworks.

7. The aluminosilicate zeolite of claim 1 , wherein the aluminosilicate zeolite is substantially free of FAU framework.

8. The aluminosilicate zeolite of claim 1 , wherein the aluminosilicate zeolite further comprises an alkaline earth metal.

9. The aluminosilicate zeolite of claim 1 , wherein the aluminosilicate zeolite has a silica-to-alumina ratio of about 25 to about 50.

10. The aluminosilicate zeolite of claim 1 , wherein the aluminosilicate zeolite has a silica-to-alumina ratio of about 25 to about 30.
