Ünlü, Derya (2020)Bu çalışmada geleceğin önemli bir biyoyakıt maddesi olarak görülen bütanolün pervaporasyon ile dehidrasyonu hedeflenmiştir. Bu amaçla UiO-66 yüklü karma matris PVA membranlar sentezlenmiştir. Membranlar çözeltiden döküm ... -
Chitosan/sodium alginate hybrid membranes modified by zeolitic imidazolate framework-90 for pervaporative dehydration of butanol
Ünlü, Derya (Springer Science and Business Media Deutschland GmbH, 2021)Biobutanol is one of the promising biofuels, which is produced by fermentation. The concentration of butanol in the fermentation broth does not usually reach 2% (by wt). To use biobutanol as fuel, it is necessary to purify ... -
Concentration of aroma compounds by pervaporation process using polyvinyl chloride membrane
Ünlü, Derya (Wiley, 2019)The organoleptic properties of beverage products have an important role in consumption and commercial success. Nowadays aroma recovery with high efficiency is an important process. Hydrophobic pervaporation is an alternative ... -
Fabrication and Application of Silicotungstic Acid/Polyvinyl Alcohol and Phosphomolybdic Acid/Polyvinyl Alcohol Hybrid Membrane for Pervaporative Dehydration of Isopropanol Solution
Ünlü, Derya (Polymer Soc Korea, 2019)Hybrid membranes were prepared by loading silicotungstic acid (STA) and phosphomolybdic acid (PMA), into polyvinyl alcohol (PVA) matrix. The membranes were characterized by Scanning electron microscopy (SEM), Fourier ... -
Production of Fuel Bioadditive "Triacetin" Using a Phosphomolybdic-Acid-Loaded PVA Membrane in a Pervaporation Catalytic Membrane Reactor
Ünlü, Derya; Hilmioglu, Nilufer Durmaz (Amer Chemical Soc, 2019)The objective of this article is to synthesize fuel bioadditive triacetin by the innovative membrane process with high yield under mild operating conditions. A phosphomolybdic-acid-loaded poly(vinyl alcohol) (PVA) membrane ... -

Özekmekci, Mehtap; Ünlü, Derya; Çopur, Mehmet (2021)Bu çalışmada, pervaporasyon prosesi ile endüstriyel atık sudan borun uzaklaştırılması incelenmiştir. Bu işlem için Saf PVA ve Amberlit IRA 743 katkılı PVA membranlar hazırlanmıştır. SEM analizinde, saf membranlarda yoğun ... -
Recovery of cutting oil from wastewater by pervaporation process using natural clay modified PVA membrane
Ünlü, Derya (Iwa Publishing, 2019)In this study, the pervaporative dehydration of the cutting oil 'diethylene glycol' (DEG) through a hydrophilic PVA membrane was investigated at various operation temperatures in the range of 333-363 K with a feed mixture ... -
Removal of boron from industrial wastewater using PVP/PVDF blend membrane and GO/PVP/PVDF hybrid membrane by pervaporation
Özekmekçi, Mehtap; Ünlü, Derya; Çopur, Mehmet (Springer, 2021)Removal of boron from water is a significant issue worldwide. Boron levels in waters containing high concentrations should be kept under control. Boron removal from the industrial wastewater released from Eti Mine Boron ... -
Synthesis of inorganic doped polyvinyl alcohol/hydroxypropyl methyl cellulose mixed matrix membrane for pervaporative separation of dimethyl carbonate/methanol mixtures
Ünlü, Derya (Korean Institute Chemical Engineers, 2020)Inorganic loaded Polyvinyl Alcohol/Hydroxypropyl Methyl Cellulose (PVA/HPMC) mixed matrix composite membranes were synthesized by filling phosphomolybdic acid (PMA) into PVA/HPMC matrix. The obtained results indicate that ...
