Abstract

A composition of matter is provided comprising hierarchically ordered crystalline microporous material having well-defined long-range mesoporous ordering of cubic symmetry. The composition possesses mesopores having walls of crystalline microporous material and a mass of mesostructure between mesopores of crystalline microporous material. Long-range ordering is defined by presence of secondary peaks in an X-ray diffraction (XRD) pattern and/or cubic symmetry observable by microscopy.

First claim

What is claimed is:

1. A composition of matter comprising hierarchically ordered crystalline microporous material having well-defined long-range mesoporous ordering of cubic symmetry comprising mesopores having walls of crystalline microporous material and a mass of mesostructure between mesopores of crystalline microporous material, wherein the long-range ordering is defined by presence of secondary peaks in an X-ray diffraction (XRD) pattern and/or cubic symmetry observable by microscopy.

2. The composition of matter as in claim 1 , wherein the mesoporous ordering of cubic symmetry is Ia-3d, Fm-3m, Pm-3n, Pn-3m or Im-3m symmetry.

3. The composition of matter as in claim 1 , wherein the mesoporous ordering of cubic symmetry is Ia-3d symmetry and secondary peaks in XRD are present at one or more of (220), (321), (400), (420) or (332) reflections.

4. The composition of matter as in claim 1 , wherein the mesoporous ordering of cubic symmetry is Ia-3d symmetry and long-range ordering is observable by microscopy viewing an electron beam down a [311], [111] or [110] zone axis, or wherein the mesoporous ordering of cubic symmetry is Fm-3m symmetry and long-range ordering is observable by microscopy viewing an electron beam down a [001] or [110] zone axis.

5. The composition of matter as in claim 1 , wherein said crystalline microporous material comprises a zeolite.

6. A hydrocracking catalyst comprising the hierarchically ordered crystalline microporous material as in claim 5 , an inorganic oxide component as a binder, and an active metal component, wherein the hierarchically ordered crystalline microporous material comprises about 0.1-99 wt % of the hydrocracking catalyst.

7. The hydrocracking catalyst as in claim 6 , wherein the inorganic oxide component is selected from the group consisting of alumina, silica, titania, silica-alumina, alumina-titania, alumina-zirconia, alumina-boria, phosphorus-alumina, silica-alumina-boria, phosphorus-alumina-boria, phosphorus-alumina-silica, silica-alumina-titania, silica-alumina-zirconia, alumina-zirconia-titania, phosphorous-alumina-zirconia, alumina-zirconia-titania and phosphorus-alumina-titania.

11. The hydrocracking catalyst as in claim 6 , wherein the active metal component comprises one or more metals selected from the Periodic Table of the Elements IUPAC Groups 6, 7, 8, 9 or 10.

12. A method for hydrocracking hydrocarbon oil, comprising: hydrocracking hydrocarbon oil with the hydrocracking catalyst of claim 11 .

13. The composition of matter as in claim 1 , wherein said crystalline microporous material is a zeolite having a framework selected from the group consisting of AEI, *BEA, CHA, FAU, MFI, MOR, LTL, LTA and MWW.

14. The composition of matter as in claim 1 , wherein said crystalline microporous material is a zeolite having FAU framework.

15. The composition of matter as in claim 1 , wherein said crystalline microporous material comprises a zeolite-type material selected from the group consisting of aluminophosphates, silicon-substituted aluminophosphates, metal-containing aluminophosphates and zeolitic siliceous only framework material.

16. A composition of matter comprising hierarchically ordered crystalline microporous material having well-defined long-range mesoporous ordering of cubic symmetry comprising mesopores having walls of crystalline microporous material and a mass of mesostructure between mesopores of crystalline microporous material, wherein at least a portion of the mesopores contain micelles of supramolecular templates shaped to induce mesoporous ordering of cubic symmetry, and wherein the supramolecular templates possess one or more dimensions larger than dimensions of micropores of the crystalline microporous material to constrain diffusion into micropores of the crystalline microporous material, wherein the dimensions relate to a head group of a supramolecular template, a tail group of a supramolecular template, or a co-template arrangement that constrain diffusion into micropores of the crystalline microporous material.

17. The composition of matter as in claim 16 , wherein said crystalline microporous material comprises a zeolite.

18. The composition of matter as in claim 16 , wherein said crystalline microporous material is a zeolite having a framework selected from the group consisting of AEI, *BEA, CHA, FAU, MFI, MOR, LTL, LTA and MWW.
