ZIF filled PDMS mixed matrix membranes for separation of solvent vapors from nitrogen
Sahin, Fatma; TOPUZ, BERNA; Kalıpçılar, Halil (Elsevier BV, 2020-03-15)
The efficiency of chemical processes can be improved by recovering high value volatile organic compounds (VOCs). For this purpose PDMS based mixed matrix membranes were prepared by using ZIF-7, ZIF-8, ZIF-67, ZIF-71 and ZI...
Preparation and characterization of supported PES membranes
TOPUZ, BERNA; Yılmaz, Levent; Kalıpçılar, Halil (Journal of the Faculty of Engineering and Architecture of Gazi University, 2019-01-01)
In the present study. polyethersulfone (PES) membranes on a macroporous alumina support was prepared by solvent-deposition method to separate H-2/CH4 mixture. The membrane solution viscosities were determined in order to u...
The Gas Permeation Characteristics of Ternary Component Mixed Matrix Membranes Prepared Using ZIF-8 with a Large Range of Average Particle Size
Ayas, Ilhan; Yılmaz, Levent; Kalıpçılar, Halil (2018-11-28)
ZIF-8 crystals with average particle sizes of 14, 23, 65, 144, and 262 nm were synthesized to prepare poly(ether sulfone) based mixed matrix membranes with 10 and 20% loading. The membranes were characterized by measuring ...
Synthesis of ZIF-7, ZIF-8, ZIF-67, and ZIF-L from recycled mother liquors
Sahin, Fatma; Topuz, Benia; Kalıpçılar, Halil (2018-05-01)
ZIF-8, ZIF-L, ZIF-7 and ZIF-67 were synthesized from fresh and recycled synthesis solutions. ZIF-8, ZIF-L and ZIF-67 includes Zn2+, while ZIF-67 includes Co2+. ZIF-67 was synthesized in dimethyl formamide, while the others...
MFI TİPİ ZEOLİT MEMBRANLARIN YÜKSEK SICAKLIKTA GERİ DÖNGÜLÜ AKIŞ SİSTEMİNDE SENTEZİ
TOPUZ, BERNA; Saka Onder, Aylin; Kalıpçılar, Halil (2018-05-01)
: In this study, MFI type zeolite membranes were synthesised in a recirculating flow system at elevated temperatures. MFI membranes were prepared on the inner surface of the seeded tubular alumina supports in the 140-160oC...
Dehydration of Industrial Byproduct Solutions for Recycling via Pervaporation-Adsorption Hybrid Process
Büküşoğlu, Emre; Kalıpçılar, Halil; Yılmaz, Levent (2018-02-14)
Dehydration of used solvents in the printing and packaging industry is required in order to reuse or increase the commercial value of the solvents. In this study, a pervaporation-liquid-phase adsorption hybrid process for ...
Investigation and comparison of mixed matrix membranes composed of polyimide matrimid with ZIF-8, silicalite, and SAPO-34
Carter, D.; Tezel, F. H.; Kruczek, B.; Kalıpçılar, Halil (2017-12-15)
Mixed Matrix type membranes (MMMs) containing 10 wt% of either silicalite, SAPO - 34, and ZIF - 8 in polyimide Matrimid were fabricated and tested for their suitability to separate a number of gas mixtures by conducting si...
Synthesis of ZSM-5 and SAPO-34 membranes in a high temperature-pressure recirculating-flow system
TOPUZ, BERNA; Onder, Aylin; Bowen, Travis C.; Kalıpçılar, Halil (Elsevier BV, 2017-01-01)
MFI and SAPO-34 type zeolite membranes were prepared on tubular alumina supports in a recirculating flow system at elevated temperatures and reported for the first time in the literature. During membrane synthesis, the syn...
Effect of three different PEO-containing additives on the fouling behavior of PES-based ultrafiltration membranes
Kaltali, G.; Kalıpçılar, Halil; Çulfaz Emecen, Pınar Zeynep (2015-08-17)
PES-based hollow fiber membranes were fabricated using three different PEO-containing additives (PEG-10 k, Pluronic (R) F127 and Triton (R) X100) in the starting polymer dope. All additives enhanced pure water permeance si...
Synthesis of ZIF-8 from recycled mother liquors
Demir, Nilay Keser; Topuz, Berna; Yılmaz, Levent; Kalıpçılar, Halil (2014-11-01)
The effect of the methanol/Zn(NO3)(2) molar ratio on the particle size, BET surface area and on the rate of the crystallization have been studied. The use of excess methanol leads to a decrease in particle size and rate of...
