Abstract: The present application relates to absorbents comprising tetraamine ligands grafted onto metal-organic frameworks and a method for using same for CO2 capture from fossil fuel combustion sources to reduce emissions. In particular, this application relates to capturing >90% by volume, preferable >99% by volume, CO2 emissions such that the emissions are negative, essentially removing CO2 from the combustion air.

Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand. Multidentate organic ligands comprising first and second binding sites bridged together with a third binding site comprising a diimine moiety may alleviate these issues, particularly when using a preformed metal cluster as a metal source to form a MOF. Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. Particular MOFs may comprise N,N′-di(1H-pyrazol-4-yl)ethane-1,2-diimine as a multidentate organic ligand.

Abstract: Methods are provided for appending amines to metal organic framework (MOF) compositions. In some aspects, the methods can allow for appending of amines in the solution or synthesis solution used for synthesizing a MOF. In such aspects, an amine-appended MOF can be formed without having to first separate and dry the underlying non-amine-appended MOF composition. In other aspects, amines can be appended to an existing MOF composition by exposing the MOF to a suitable amine in a protic solvent, such as water or an alcohol.

Abstract: Contactor structures are provided that can allow for improved heat management while reducing or minimizing the potential for contamination of process gas streams with heat transfer fluids. The contactor structures can include one or more sets of flow channels for process gas flows, such as gas flows introduced to allow adsorption of components from a gas stream or gas flows introduced to facilitate desorption of previously adsorbed components into a purge gas stream. The process gas flow channels can correspond to flow channels defined by a structural material of unitary structure. The unitary structure can correspond to the entire contactor, or the unitary structure can correspond to a monolith that forms a portion of the contactor. The contactor structures can also include one or more sets of flow channels for heat transfer fluids. The heat transfer flow channels can also be defined by the structural material of a unitary structure.

Abstract: Functionalized polymer compositions are provided that can have beneficial properties for CO2 sorption and/or desorption. The functionalized polymer compositions can be based on polymers of intrinsic microporosity. The polymers of intrinsic microporosity can then be at least partially reacted to form polymers functionalized with guanidine and/or amidine derivatives where at least a portion of the polymeric repeat units have a substituent that includes a guanidine derivative and/or amidine derivative as a functional group. Optionally, the functionalized polymers of intrinsic microporosity can be further reacted in order to further modify the guanidine derivative and/or amidine derivative that is substituted at one or more locations of a polymeric repeat unit.
