Patent ID: 8524625

Claim:
A method of forming a material comprising at least one mesostructured zeolite one-phase hybrid single crystal having long-range crystallinity and enhanced hydrothermal stability and microporosity retention after regeneration, comprising the steps of: (a) providing a fully-crystalline non-mesoporous zeolite having long-range crystallinity wherein said non-mesoporous zeolite comprises a faujasite; (b) adding rare earth elements to said non-mesoporous zeolite; (c) acid washing said non-mesoporous zeolite to thereby form an acid-washed zeolite, wherein said acid washing modifies the silicon to aluminum ratio in said non-mesoporous zeolite; and (d) forming a plurality of mesopores within said acid-washed zeolite to thereby form said mesostructured zeolite, wherein said forming occurs in the presence of at least one surfactant.
