Alumina-coated, silicon carbide monoliths were used as supports for B-ZSM-5 zeolite membranes, which were synthesized by in situ hydrothermal crystallization. Both 2 turn x 2 mm (66 channels) and 4 mm x 4 mm (22 channels) monoliths with effective membrane area/volume ratios of 10.6 and 7.2 cm(2)/cm(3), respectively, were used. The membranes separated C-4 and C-6 hydrocarbon isomer vapor mixtures with high selectivities. The selectivities and permeances were comparable to tubular ZSM-5 membranes for butane isomers. The highest ideal selectivities at 473 K were 34 for n-C4H10/i-C4H10 and 77 for H-2/i-C4H10. The highest n-C4H10/i-C4H10 separation selectivity was 35 at 373 K, and the highest n-hexane/2,2-dimethylbutane separation selectivity was 247 at 436 K.

A B-ZSM-5 zeolite membrane was synthesized on a monolith support containing 60 channels (2 mm x 2 mm.). The membrane showed a n-C4H10/i-C4H10 ideal selectivity at 373 K of 79 and a separation selectivity of 30.
Production and performance evaluation of ZIF-8 based binary and ternary mixed matrix gas separation membranes
Keser, Nilay; Yılmaz, Levent; Kalıpçılar, Halil; Department of Chemical Engineering (2012)
Mixed matrix membranes (MMMs) have gained importance because they combine the desirable properties of the polymers and the organic/inorganic filler materials and they may have a very big potential. In this study polyethersulfone (PES) was used as polymeric material, and Zeolitic Imidazolate Framework-8 (ZIF-8) was used as porous filler material, and 2-hydroxy 5-methyl aniline(HMA), was used as a third component in membrane formulation. In this study, ZIF-8 crystals were synthesized with varying particle siz...

Gulsen, D; Hacarloglu, P; Toppare, Levent Kamil; Yılmaz, Levent (2001-02-15)
Mixed matrix composite membranes of a conducting polymer, polypyrrole (PPy), and an insulating polymer, polybisphenol-A-carbonate (PC) were prepared by a combined in-situ polymerization and solvent evaporation. Mixed matrix composite membranes were synthesized to combine the good gas transport properties of conductive polymer, PPy, with good mechanical properties of PC.
Improvement of PEMFC performance with Nafion/inorganic nanocomposite membrane electrode assembly prepared by ultrasonic coating technique
Devrim, Yilser; Erkan, Serdar; BAÇ, NURCAN; Eroğlu, İnci (2012-11-01)
electrode assemblies with Nafion/nanosize titanium silicon dioxide (TiSiO4) composite membranes were manufactured with a novel ultrasonic-spray technique and tested in proton exchange membrane fuel cell (PEMFC). Nafion/TiO2 and Nafion/SiO2 nanocomposite membranes were also fabricated by the same technique and their characteristics and performances in PEMFC were compared with Nafion/TiSiO4 mixed oxide membrane. The composite membranes have been characterized by thermogravimetric analysis, scanning electron m...
Synthesis and characterization of zirconium based bulk amorphous alloys
Saltoğlu, İlkay; Akdeniz, Mahmut Vedat; Department of Metallurgical and Materials Engineering (2004)
In recent years, bulk amorphous alloys and nanocrystalline materials have been synthesized in a number of ferrous and non-ferrous based alloys systems, which have gained some applications due to their unique physico-chemical and mechanical properties. In the last decade, Zr-based alloys with a wide supercooled liquid region and excellent glass forming ability have been discovered. These systems have promising application fields due to their mechanical properties; high tensile strength, high fracture toughne...
