Composite membranes with cross-linked matrimid selective layer for gas separation Autori: Carmen Nistor, Marcel Popa, Sergey Shishatskiy, Suzana Pereira NunesData aparitiei: November/December 2008 Revista: Environmental Engineering and Management Journal › Vol. 7 › Nr. 6 ISSN: 1843 - 3707  Format PDFAbstract
In the present work, composite membranes were developed for separation of hydrogen from its mixtures with other gases. The composite membranes were characterized by single gas permeation and scanning electron microscopy. Gas transport properties have been determined for four gases (H2, CH4, N2, CO2). The influence of cross-linking on transport was measured. H2/CH4 selectivity values up to 115 were obtained. The resulting membranes have a selectivity of H2/CH4 close to intrinsic selectivity of Matrimid 5218. |
