    Abstract: Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced in powder form. Extrusion of powder-form MOFs to produce shaped bodies has heretofore proven difficult due to loss of surface area and poor crush strength of MOF extrudates, in addition to phase transformations occurring during extrusion. The choice of mixing conditions and the mixing solvent when forming MOF extrudates can impact these factors. Extrudates comprising a MOF consolidated material may feature the MOF consolidated material having a BET surface area of about 50% or greater relative to that of a pre-crystallized MOF powder material used to form the extrudate. X-ray powder diffraction of the extrudate shows about 20% or less conversion of the MOF consolidated material into a phase differing from that of the pre-crystallized MOF powder material.

    Abstract: Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.

    Abstract: Methods making a metal-organic framework extrudate in an extruder comprising the steps of: (a) mixing a metal-organic framework material with an extrusion aid to form a metal-organic framework extrudate mixture; and (b) extruding the metal-organic framework mixture in the extruder to produce the metal-organic framework extrudate where the pressure within the extruder is reduced between about 10% to about 55% when compared to pressure within the extruder when extruding the metal-organic framework material without the extrusion aid. The extrusion aid can be a liquid extrusion aid, a solid extrusion aid and/or a polymeric extrusion aid.
