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: 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.

Abstract: Processes for the catalytic conversion of alcohols and/or ethers to olefins over zeolite catalysts are described. ZSM-48 and metal containing variants, such as Zn ZSM-48, produce high yields of olefins, particularly ethylene or C3+ olefins, between 200 and 500° C.

Abstract: Processes for the catalytic conversion of alcohols and/or ethers to olefins over zeolite catalysts are described. Self-bound ZSM-5 and metal containing variants, such as Zn ZSM-5, produce high yields of olefins, particularly C3+ olefins, between 250 and 450° C.
