The effect of low molecular weight additive (LMWA) loading on the gas permeation properties of pure PES and PES/SAPO-34 membranes was investigated. 2-hydroxy 5-methyl aniline (HMA) was selected as LMWA. Membranes were prepared by solvent-evaporation method and annealed above the glass transition temperature (T-g) of PES. They were characterized by single gas permeability measurements of H-2, CO2, and CH4 as well as scanning electron microscopy (SEM), and differential scanning calorimetry (DSC). The H-2/CH4 selectivities of pure PES and SAPO-34/PES membranes were 71.31 and 61.02, respectively. The incorporation of zeolite SAPO-34 to neat PES membranes resulted in higher permeabilities for all gases with slight decrease in CO2/CH4 and H-2/CH4 ideal selectivities compared to pure PES membranes. However, PES/SAPO-34/HMA membranes had significantly higher ideal selectivities than pure PES, PES/SAPO-34, and PES/HMA membranes, for example the H-2/CH4 selectivity of HMA/SAPO-34/PES membrane was 175.8, which was three times as high as the H-2/CH4 selectivity of PES/SAPO-34 membrane. The permeabilities of all the gases through PES/SAPO-34/HMA membranes were also higher than those through PES/HMA membranes. Ternary component membranes revealed better gas permeation performance compared to pure polymeric and binary component membranes.

Development of alumina supported ternary mixed matrix membranes for separation of H-2/light-alkane mixtures Topuz, Berna; Yılmaz, Levent; Kalıpçılar, Halil (2012-10-01) Ternary component mixed matrix membrane was prepared from PES, SAPO-34 and 2-hydroxy 5-methyl aniline on a macroporous alumina disk by the solvent evaporation method in order to investigate the effect of existence of an inorganic support. The membrane and its pure PES/Alumina counterpart were characterized by single gas permeability measurements of H-2, CH4, C2H6 and C3H8. The corresponding H-2/CH4 selectivities of membranes were 71.3 and 41. The membranes were also used to separate equimolar mixtures of H-...
Effect of feed gas composition on the separation of CO2/CH4 mixtures by PES-SAPO 34-HMA mixed matrix membranes Cakal, Ulgen; Yılmaz, Levent; Kalıpçılar, Halil (2012-11-01) The performance of zeolite and low molecular weight additive incorporated polyethersulfone (PES) membranes on the separation of CO2/CH4 mixtures at 35 degrees C was investigated. Four types of membranes, pure PES, PES/ 2-hydroxy 5-methyl aniline (HMA), PES/SAPO-34 and PES/SAPO-34/HMA, were prepared by solvent evaporation method. The CO2 concentration in the feed was varied between 5 and 70% by volume. PES/SAPO-34 membranes had a total permeability coefficient of 3 Barrer for an equimolar mixture, which was ...
Development of polybenzimidazole/graphene oxide composite membranes for high temperature PEM fuel cells Uregen, Nurhan; Pehlivanoglu, Kubra; Ozdemir, Yagmur; DEVRİM, YILSER (2017-01-26) In this study, phosphoric acid doped Polybenzimidazole/Graphene Oxide (PBI/GO) nano composite membranes were prepared by dispersion of various amounts of GO in PBI polymer matrix followed by phosphoric acid doping for high temperature proton exchange membrane fuel cell (HT-PEMFC) application. The structure of the PBI/GO composite membranes was investigated by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and by thermogravimetric analysis (TGA). The introduction of GO into the FBI polymer matri...
Preparation and characterization of sulfonated polysulfone/titanium dioxide composite membranes for proton exchange membrane fuel cells Devrim, Yiser; Erkan, Serdar; BAÇ, NURCAN; Eroğlu, İnci (2009-05-01) In the present study, sulfonated polysulfone (sPS)/titanium dioxide (TiO2) composite membranes for use in proton exchange membrane fuel cells (PEMFCs) were investigated. Polysulfone (PS) was sulfonated with trimethylsilyl chlorosulfonate in 1,2 dichloroethane at ambient temperatures. It was shown that the degree of sulfonation is increased with the molar ratio of the sulfonating agent to PS repeat unit. The degree of sulfonation was determined by elemental analysis and H-1 NMR was performed to verify the su...
Polybenzimidazole based nanocomposite membranes with enhanced proton conductivity for high temperature PEM fuel cells Ozdemir, Yagmur; Uregen, Nurhan; DEVRİM, YILSER (2017-01-26) In this study, phosphoric acid doped PBI nanocomposite membranes were prepared by dispersion of various amounts of inorganic nanoparticles in PBI polymer followed by phosphoric acid (H3PO4) doping for high temperature proton exchange membrane fuel cells (HT-PEMFC). All of the PBI composite membranes were cast from the same FBI polymer with the same molecular weight. Titanium dioxide (TiO2), silicon dioxide (SiO2) and inorganic proton conductor zirconium phosphate (ZrP) were used as inorganic fillers. The PB...
