At Pacific Northwest National Laboratory, mechanical robust composite materials were developed and tested from a gas mixture relevant to potential future nuclear reprocessing applications. Several composite materials were produced using the wet granulation method, which is very scalable. Metal organic framework (MOFs) composite materials were produced using a well-known polymer as binder (poly methyl methyl acrylate) to convert a fine microcrystalline powder into shaped bodies while preserving the intrinsic properties of MOFs. The resulting MOF composite shows an improved mechanical stability (>100% compare to MOF beads without polymer) in comparison with nuclear-grade activated-carbon pellets and with minimal loss of adsorption capacity (~10% reduction) at room temperature.
