Effect of preparation parameters on performance of dense homogeneous polycarbonate gas separation membranes
Hacarlioglu, P; Toppare, Levent Kamil; Yılmaz, Levent (Wiley, 2003-10-17)
The aim of this study is to determine the effect of preparation parameters on the membrane permeation mechanism and separation performances of dense homogeneous poly(bisphenol A carbonate) (PC) membranes. Blade-casting and drop-casting techniques are used for casting films from solutions with varying concentrations. Chloroform and methylene chloride are used to determine the effect of the properties of the casting solvent. Permeation measurements are done with Ar, N-2, O-2, CH4, CO2, and H, gases. The selec...

Effect of preparation and operation parameters on performance of polyethersulfone based mixed matrix gas separation membranes
Karatay, Elif; Yılmaz, Levent; Department of Chemical Engineering (2009)
Membrane processes have been considered as promising alternatives to other competing technologies in gas separation industry. Developing new membrane morphologies are required to improve the gas permeation properties of the membranes. Mixed matrix membranes composing of polymer matrices and distributed inorganic/organic particles are among the promising, developing membrane materials. In this study, the effect of low molecular weight additive (LMWA) type and concentration on the gas separation performance o...
Effect of operating parameters on performance of additive/ zeolite/ polymer mixed matrix membranes
Oral, Edibe Eda; Yılmaz, Levent; Kalıpçılar, Halil; Department of Chemical Engineering (2011)
Membrane based separation techniques have been widely used and developed over decades. Generally polymeric membranes are used in membrane based gas separation; however their gas separation performances are not sufficient enough for industrial feasibility. On the other hand inorganic membranes have good separation performance but they have processing difficulties. As a consequence mixed matrix membranes (MMMs) which comprise of inorganic particles dispersed in organic matrices are developed. Moreover, to enh...
Effect of preparation parameters on the performance of conductive composite gas separation membranes
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.
