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.

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 operating parameters on selective separation of heavy metals from binary mixtures via polymer enhanced ultrafiltration
Muslehiddinoglu, J; Uludağ, Yusuf; Ozbelge, HO; Yılmaz, Levent (Elsevier BV, 1998-03-18)
Performance of continuous polymer enhanced ultrafiltration (PEUF) method was investigated for removal of mercury and cadmium from binary mixtures. This method includes the addition of polyethyleneimine (PEI) as a water soluble polymer to bind the metals, which was followed by ultrafiltration operation performed on both laboratory and pilot scale systems. The influence of various operating parameters such as temperature, metal/polymer ratio, presence of calcium ions and pH on retention of metals and permeate...
Effect of ionic strength on the performance of polymer enhanced ultrafiltration in heavy metal removal from aqueous solutions
İslamoğlu, Sezin; Yılmaz, Levent; Department of Chemical Engineering (2006)
Effect of ionic strength on the efficiency of heavy metal removal and recovery from aqueous solutions via continuous mode polymer enhanced ultrafiltration (PEUF) method was examined. Application of PEUF to divalent ions of cadmium, nickel and zinc after their prior linking with polyethylenimine (PEI) results in complete removal of metal ions from single component aqueous solutions at high pHs. Binding ability and hence the extent of metal retention in high ionic strength medium exhibits differences between ...
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 ...
Synthesis and separation properties of B-ZSM-5 zeolite membranes on monolith supports
Kalıpçılar, Halil; Noble, RD; Falconer, JL (2002-12-01)
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 i...
