Embodiment Construction

[0011] A new class of MMM containing a specific type of microporous solid material as filler has now been developed, which retains its polymer processability and options for improved gas separation due to the excellent molecular sieving and sorption properties of the microporous material. sex. The fillers used herein are MOFs and related structures.

[0012] More particularly, the present invention relates to MOF-polymer MMMs (or MOF-polymer hybrid matrix membranes) containing high surface area MOF materials as fillers. These new MMMs have utility for the separation of various gas mixtures. One such separation of considerable industrial importance is the removal of CO from natural gas 2 . MMM allows carbon dioxide to diffuse through the membrane at a faster rate than methane. Carbon dioxide has a faster permeation rate than methane due to its higher solubility in the membrane, higher diffusion coefficient, or both. Thus, the concentration of carbon dioxide accumulates on ...

Abstract

Metal-organic framework (MOF)-polymer mixed matrix membranes (MOF-MMMs) can be prepared by dispersing high surface area MOFs into a polymer matrix. The MOFs allow the polymer to infiltrate the pores of the MOFs, which improves the interfacial and mechanical properties of the polymer and in turn affects permeability. These mixed matrix membranes are attractive candidates for practical gas separation applications such as CO2 removal from natural gas.

Description

[0001] Claiming priority from an earlier national application [0002] This application claims priority to Provisional Application No. 61 / 286,435, filed December 15, 2009, the contents of which are incorporated herein by reference. Background of the invention [0003] The present invention relates to the use of metal organic frameworks (MOFs) in mixed matrix membranes. More particularly, the present invention relates to the use of MOFs in specific settings that provide enhanced gas separation, including the separation of carbon dioxide and methane. [0004] Methods of separating gases with membranes have undergone major developments since the introduction of the first membrane-based industrial hydrogen separation process about 20 years ago. The design of new materials and efficient methods will further advance membrane gas separation methods over the next decade. [0005] The gas transport properties of many glassy and rubbery polymers have been measured, driven by the inves...
