Ink compositions are provided for using solvent-based additive manufacturing (SBAM) techniques to form contactor structures and/or structures for use in an adsorption or absorption contactor. Methods forming a contactor using SBAM are also provided. The ink compositions can include a substantial content of adsorbent particles to provide enhanced adsorption by a contactor. Metal organic framework (MOF) structures and zeotype framework structures are examples of types of adsorbent particles that can be incorporated into an ink composition for forming a contactor structure by SBAM. The ink can further include a polymeric component that can serve as the structural component of a polymeric structural material produced by the additive manufacturing method. Such a structural material can correspond to a polymeric material with incorporated adsorbent particles. In some aspects, the polymeric structural material and/or the adsorbent particles can have selectivity for adsorption of COfrom a process fluid flow.

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.

Advantaged adsorption contactors

A method of forming a molecular separation device is provided. The method comprises growing or depositing a silica MFI zeolite coating on a ceramic support. The method further comprises growing a ZIF-8 coating on the silica MFI zeolite coating. Growing the ZIF-8 coating on the silica MFI zeolite comprises applying a first reactant fluid including a metal salt and a second reactant fluid including an imidazole reactant to the silica MFI zeolite coating. Growing the ZIF-8 coating on the silica MFI zeolite further comprises reacting the first and second reactant fluid with the silica MFI zeolite coating to produce the ZIF-8 coating. In certain implementations, at least a portion of the ZIF-8 coating is interspersed with a portion of the silica MFI coating. A molecular separation device including the ZIF-8 coating and the silica MFI zeolite is also disclosed.

Disclosed herein is a molecularly-mixed composite membrane comprising an amorphous scrambled porous organic compound (ASPOC) material and a polymer. With current developments in membrane technologies, there exists a need for largely scalable membranes and improved performance with difficult molecular separations. Mixed Matrix Membranes improve separation performance to a degree, but also increase the membrane defects as the filler material aggregates into particles that disrupt the membrane matrix. The disclosed membrane is configured to reduce defects and increase homogeneity. The disclosed ASPOC material avoids aggregation and disperses uniformly in the polymer matrix, creating a molecularly-mixed composite membrane with improved separation performance. Also disclosed herein are methods for making the same.
