Abstract
Provided are a novel form of AFX zeolite, a novel synthesis technique for producing pure phase small pore zeolites, 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.
Claims8
An aluminosilicate zeolite comprising at least about 90% phase pure AFX framework, wherein the aluminosilicate zeolite has a short hexagonal prism morphology.
A catalyst for treating an exhaust gas comprising a pure phase AFX zeolite that comprises an extra-framework metal selected from V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, Ru, Rh, Pd, Ag, W, Re, Os, Ir, Pt, and Au, wherein the zeolite has a short hexagonal prism morphology.
