Membrane Technology and Research, Inc. (MTR) and partners Susteon and the Energy and Environmental Research Center (EERC) are maturing a 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. Project work is focused on the goal of scaling-up a second-generation Proteus membrane, including the fabrication of high-temperature prototype modules using second-generation (Gen-2) membranes and validating module performance in laboratory tests, followed by designing, constructing, and installing a prototype test system at EERC for parametric and lifetime testing of the modules with actual coal-derived syngas.
