Ohio State University (OSU) will develop a cost-effective design and fabrication process for a novel amine-containing transformational membrane to capture carbon dioxide (CO₂) from coal-derived syngas. The membrane consists of a CO₂-selective and permeable layer on top of a nanoporous polymer support and exhibits chemical stability to hydrogen sulfide (H₂S) gas. The membrane operates based on the facilitated transport mechanism, in which CO₂ transfer through the membrane is enhanced via reaction with amino groups, while hydrogen (H₂) is rejected due to the absence of reaction. Hydrogen sulfide can permeate through the membrane significantly faster than CO₂ and can be removed in the front section of the membrane module, resulting in less than 30 ppm H₂S in the retentate. The membrane will be used in a single-stage membrane process utilizing modules in commercial spiral-wound configuration with a minimal pressure drop. OSU will synthesize and characterize transformational membranes, scale up the best performing membrane using a continuous roll-to-roll fabrication method, and fabricate at least nine prototype membrane modules with an approximate membrane area of 800 cm². Parametric testing of the membrane modules at 20-32 bar and 100-120°C will be performed to identify conditions for continuous steady-state operation, which will be conducted using simulated syngas at OSU for at least 200 hours. The membrane test data will be used to complete a high-level techno-economic analysis (TEA) and finalize the state point data table. American Electric Power will provide consulting support on the TEA and Microdyn-Nadir US Inc. will provide consultation on membrane scale-up and module fabrication.
