Arizona State University (ASU), in collaboration with the University of South Carolina (USC), will develop a high-temperature, high-pressure ceramic-carbonate dual-phase (CCDP) membrane reactor for water-gas-shift (WGS) reaction to produce a high concentration hydrogen (H₂) stream with carbon dioxide (CO₂) capture. The CCDP membrane is composed of a porous ceramic phase that serves as a support layer and a molten carbonate phase infiltrated into the support. The reactor is expected to produce separate CO₂- and H₂-rich streams with single-stage carbon monoxide conversion and CO₂ recovery of 90 percent. Previous research at ASU and USC has shown successful fabrication and unique CO₂ permeation/separation properties of CCDP membranes of different materials in disk and tubular geometries. During this project, the project team will design and fabricate CCDP membranes with improved CO₂ permeance and mechanical strength for testing in a lab-scale reactor with simulated coal-derived syngas. The membrane reactor will be designed to operate at high temperature (700-900^oC) and pressure (20-30 atm) and will be able to withstand impurities in the syngas, such as hydrogen sulfide. Experiments will be conducted to study high-pressure CO₂ permeation and WGS reaction with CO₂ capture and the results will be incorporated into a mathematical model. The experimental conditions of the system will then be optimized to produce high-purity CO₂ and H₂ streams with at least 99 percent and 90 percent purity, respectively. Process design and a techno-economic analysis will be completed for the CCDP membrane reactor incorporated in a full-scale integrated gasification combined cycle plant.
