Abstract: Monolith structures coated with porous solids are provided that can serve as structural materials for amine sorbents, such as polyamine sorbents. By using monolith structures that are coated with suitable porous solids, the sorption capacity of an amine sorbent material that is deposited on the monolith coated with the porous solid can be substantially maintained as the loading density of the amine is increased. This can allow for higher productivity sorption systems by allowing higher concentrations of amine to be effectively used while still substantially maintaining the favorable sorption characteristics of the amine sorbent.

Abstract: Systems and methods are provided for using a multi-stage capture process for capture of CO2 from air. A first or initial sorption process is used to sorb CO2 from air. After sorption from the air is complete, the desorption step of the initial stage is used to form a secondary CO2-containing stream that is passed into one or more additional sorption stages. This secondary CO2-containing stream can be at a concentration of roughly 1.0 vol % or more. Sorption of CO2 from the secondary CO2-containing stream is performed using a different contacting method, such as a contacting method that is higher efficiency. The second or later CO2 sorption stage can produce a CO2-containing output stream with a CO2 concentration of 80 vol % or more, or 90 vol % or more, or 95 vol % or more. This high purity output stream can then be sequestered and/or used for further processing.

Abstract: Methods are provided for synthesizing metal-organic framework compositions using synthesis mixtures with elevated solids content and/or elevated kinematic viscosity. The methods can allow for formation of MOF-274 metal-organic framework compositions, such as EMM-67 (a mixed-metal MOF-274 metal-organic composition). More generally, the methods can allow for formation of MOF structures that include multi-ring disalicylate organic linkers using synthesis mixtures that contain a reduced or minimized amount of solvent, such as down to having substantially no solvent in the synthesis mixture.

Abstract: Methods are provided for synthesizing metal organic framework compositions in an aqueous environment and/or in a mixed alcohol/water solvent. The methods can allow for formation of MOF-274 metal organic framework compositions, such as EMM-67 (a mixed metal MOF-274 metal organic framework composition). More generally, the methods can allow for formation of MOF structures that include disalicylate linkers in an aqueous environment and/or in a mixed alcohol/water solvent.
