Abstract

The present invention relates to extruded shaped bodies containing at least one metal-organic framework (MOF), methods for their preparation and their use.

First claim

The invention claimed is:

1. A method for preparing a shaped body containing a metal-organic framework material (MOF), wherein the MOF is an aluminum MOF directly produced in an aqueous solution, the method comprising the steps of
(a) mixing a composition comprising the MOF and at least one additive; and
(b) extruding the composition into a shaped body,
wherein the MOF is dried prior to step (a).

2. The method of claim 1 , wherein the composition of step (a) is dried prior to step (b).

3. The method of claim 2 , wherein the drying of the composition of step (a) prior to step (b) comprises spray-drying.

4. The method of claim 1 , wherein the MOF in step (a) is applied in the form of spheres.

5. The method of claim 1 , wherein the at least one additive comprises at least one binder that is selected from the group consisting of oxidic binders and partially organic binders.

6. The method of claim 5 , wherein the amount of the at least one binder additive based on the total weight of the shaped body is from 1 to 80 wt.-%.

7. A method of claim 1 , wherein the MOF comprises one or more of the organic compounds selected from fumarate, trimesate, 2-aminoterephthalic acid and 4,4′,4″-benzene-1,3,5-triyl-tribenzoate.

8. An extruded shaped body comprising a metal-organic framework material (MOF), wherein the extruded shaped body is prepared by the method of claim 1 .

9. The extruded shaped body of claim 8 , wherein the MOF comprises one or more of the organic compounds selected from fumarate, trimesate, 2-aminoterephthalic acid and 4,4′,4″-benzene-1,3,5-triyl-tribenzoate.

10. An extruded shaped body of claim 8 further comprising at least one additive.

11. A method of uptake of at least one substance, comprising:
providing an extruded shaped body of claim 8 ; and
bringing the at least one substance into contact with the extruded shaped body for the purposes of the at least one substance's storage, separation, controlled release, chemical reaction or as support.

12. The method of claim 11 , wherein the at least one substance is a gas or gas mixture.

13. The method of claim 12 , wherein the at least one substance is natural gas or shale gas.

14. The method of claim 13 , wherein the at least one substance is natural gas or shale gas which is stored in vehicle tanks.

15. The method of claim 5 , wherein the at least one binder is selected from the group consisting of aluminum oxide, silicone oxide, clay, cement, and silicon-organic compounds.
