Bu çalışmada, metilal/metanol ikili karışımlarının pervaporasyon prosesi ile saflaştırılması için UiO-66 katkılı PEI nanokompozit membranlar hazırlanmıştır. Membranlar, Taramalı elektron mikroskobu (SEM), Fourier dönüşümlü kızılötesi spektroskopisi (FTIR) ve Termogravimetrik analiz (TGA) ile karakterize edilmiştir. Pervaporasyon testleri farklı operasyon sıcaklıklarında, besleme metanol konsantrasyonunda, UiO-66 yükleme oranında ve membran kalınlığında gerçekleştirilmiştir. Optimum çalışma koşulları 30oC çalışma sıcaklığı, ağırlıkça %6 besleme metanol konsantrasyonu, ağırlıkça %0.5 UiO-66 katkılı PEI nanokompozit membran ve 50 µm membran kalınlığı olarak belirlenmiştir. Bu koşullar altında akı ve metanol seçicilik değerleri sırasıyla 1.48 kg/m2.h ve 80126 olarak elde edilmiştir. Elde edilen sonuçlar, pervaporasyon işlemi ile yüksek saflıkta metilal yakıt biyokatkı maddesi ve yeşil solvent elde edilebileceğini göstermektedir.

Purification of fuel bioadditive and green solvent methylal by pervaporation process using UiO-66 doped PEI nanocomposite membrane

Öz

In this study, UiO-66 doped PEI nanocomposite membranes were prepared for the purification of methylal/methanol binary mixtures by pervaporation process. Membranes were characterized by Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and, Thermogravimetric analysis (TGA). Pervaporation tests were performed at different operation temperature, feed methanol concentration, UiO-66 loading ratio and membrane thickness. The optimum operation conditions were determined as 30oC of operation temperature, 6 wt. % of feed methanol concentration, 0.5 wt. % doped PEI membrane and 50 µm of membrane thickness. Under these conditions, flux and methanol selectivity values were 1.48 kg/m2.h and 80126, respectively. The obtained results show that high purity methylal fuel bioadditive and green solvent can be acquired by pervaporation process.
