SRI’s overall goal is to develop a technically and economically viable carbon dioxide (CO2) capture system based on a high-temperature polybenzimidazole (PBI) polymer hollow-fiber membrane separation technology. This is intended for deployment at elevated temperatures to separate hydrogen (H2) and CO2 in shifted syngas, enabling pre-combustion carbon capture in integrated gasification combined cycle (IGCC) power plants. Current project goals are to extend previous work on PBI hollow-fiber membranes and bench-scale test skids with second generation (Gen-2) fibers having improved selectivity. These are to be deployed in bench-scale testing on actual coal-derived syngas from an oxygen-blown gasifier. Results are to demonstrate if Gen-2 PBI-based hollow-fiber membranes provide a pathway to achieving the U.S. Department of Energy’s (DOE) pre-combustion capture targets.
