Universidad de Zaragoza Hydrogen Separation at High Temperature with Dense and Asymmetric Membranes Based on PIM-EA(H2)-TB/PBI Blends 2018 Access copy available to the general public Unrestricted The preparation of dense and asymmetric flat membranes from the blending of polybenzimidazole (PBI) and (1.5-20 wt %) of a polymer of intrinsic microporosity (PIM-EA(H2)-TB) is reported. Thermal characterization validated the blend by revealing a single glass transition temperature, which suggests the absence of polymer phase segregation. In addition, the decomposition activation energy and d-spacing of the blends follow trends that correlate with the amount of PIM component. The membranes have been tested for the separation of H2/CO2 mixtures. The properties of the dense membranes, which also incorporate zeolitic imidazolate-8 (ZIF-8) nanoparticles, helped understanding of the behavior of the PIM/PBI blends by which phase inversion results in high separation performance asymmetric membranes. Asymmetric membranes show H2/CO2 selectivities of 23.8 (10/90 wt % PIM/PBI) and 19.4 (20/80 wt % PIM/PBI) together with respective H2 permeances of 57.9 and 83.5 GPU at 250 °C and 6 bar feed pressure. The gas separation performance of these asymmetric blends has been fitted to an empirical model, showing the influence of the amount of PIM and the feed pressure. info:eu-repo/grantAgreement/ES/DGA/T43-17R info:eu-repo/grantAgreement/EC/FP7/608490/EU/Energy efficient MOF-based Mixed Matrix Membranes for CO2 Capture/M4CO2 info:eu-repo/grantAgreement/ES/MEC/FPU2014 info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2016-77290-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.375 2018 ENGINEERING, CHEMICAL 33 / 138 = 0.239 2018 Q1 T1 0.907 2018 Chemical Engineering (miscellaneous) 2018 Q1 Industrial and Manufacturing Engineering 2018 Q1 Chemistry (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-9934-1707 Zornoza, B.
