Membrane Technology and Research, Inc. (MTR) and partners Susteon and the Energy and Environmental Research Center (EERC) are maturing technology based on a novel, hydrogen (H2)-selective, multi-layer composite polymer membrane called Proteus™ for use in the separation of H2 from post-shifted syngas. The current project focuses on the scale-up of a second-generation Proteus™ membrane, including fabrication of high-temperature prototype modules using Gen-2 membranes and validating module performance in laboratory tests. A prototype module test system will be designed, built, and installed at EERC for parametric and lifetime testing of the modules with actual coal-derived syngas. The process will be optimized, and a techno-economicanalysis (TEA) will be updated based upon the results of testing.
