The main objective is to scale-up and field-validate the technical feasibility of the University of Southern California's (USC) membrane- and adsorption-enhanced water-gas shift (WGS) process that employs a carbon molecular sieve (CMS) membrane reactor (MR), followed by an adsorption reactor (AR), for precombustion carbon dioxide (CO2) capture. The project begins at Technology Readiness Level (TRL) 4, as the system prototype has already been validated in the laboratory on simulated syngas (under predecessor project FE0026423). The project aims to end at TRL 5, via scaling-up of the prototype system and its testing on actual syngas at the University of Kentucky (UKy). Project tasks include designing, constructing, assembling, and validating the bench-scale experimental MR-AR system; preparing suitable membranes, adsorbents, and catalysts needed for the bench-scale system; and deploying the unit at UKy and testing system performance using real syngas. Results are to be used to complete an updated process technoeconomic analysis (TEA) and environmental, health, and safety (EH&S) risk assessment.
