Mixed matrix membranes based on 6FDA polyimide with silica and zeolite microsphere dispersed phases 2015 Access copy available to the general public Unrestricted Mixed matrix membranes (MMMs) prepared with 6FDA-DAM polymer using ordered mesoporous silica MCM-41 spheres (MSSs), Grignard surface functionalized MSSs (Mg-MSSs) and hollow zeolite spheres are studied to evaluate the effects of surface modification on performance. Performance near or above the so-called permeability-selectivity trade-off curve was achieved for the H2/CH4, CO2/N2, CO2/CH4, and O2/N2 systems. Two loadings (8 wt % and 16 wt %) of MSSs were tested using both constant volume and Wicke-Kallenbach sweep gas permeation systems. Besides single gas H2, CO2, O2, N2, and CH4 tests, mixed gas (50/50 vol %) selectivities were obtained for H2/CH4, CO2/N2, CO2/CH4, and O2/N2 and found to show enhancements vs. single gases for CO2 including cases. Mg-MSS/6FDA-DAM was the best performing MMM with H2/CH4, CO2/N2, CO2/CH4, and O2/N2 separation selectivities of 21.8 (794 Barrer of H2), 24.4 (1214 Barrer of CO2), 31.5 (1245 Barrer of CO2), and 4.3 (178 Barrer of O2), respectively. info:eu-repo/grantAgreement/ES/MINECO/MAT2013-40566-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.98 2015 ENGINEERING, CHEMICAL 23 / 135 = 0.17 2015 Q1 T1 1.085 2015 Biotechnology 2015 Q1 Environmental Engineering 2015 Q1 Chemical Engineering (miscellaneous) 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-4954-1188 Téllez, C.
