چکیده
Bu çalışmada, metilal/metanol karışımlarının ayrılması için pervaporasyon işlemi kullanılmıştır. Metanole afinitesinden dolayı membran hazırlamak polieterimid (PEI) polimeri seçilmiştir. ZIF-8, katkı maddesi olarak ZIF-8 katkılı PEI membranı sentezlenmiş ve karakterize edilmiştir. Membranların kimyasal bağ yapısı, termal dayanımı morfolojisi sıraısyla Fourier dönüşümü kızılötesi spektroskopisi (FTIR), Termogravimetrik Analiz (TGA) Taramalı elektron mikroskobu (SEM) ile analiz ayırma performansı farklı çalışma sıcaklıklarında, besleme metanol konsantrasyonlarında yükleme oranlarında incelenmiştir. Optimum proses koşulları, 20°C operasyon sıcaklığı, ağırlıkça %6 konsantrasyonu %0.5 oranı belirlenmiştir. Akı seçicilik değerleri bu koşullar altında sırasıyla 0.57 kg/m2h akı 8169 seçiciliği

EFFECT OF OPERATING CONDITIONS ON THE DEHYDRATION OF TOLUENE BY PERVAPORATION USING A POLYVINYL ALCOHOL MEMBRANE
The effects of operating parameters such as feed temperature and permeate-side pressure on the performance of a commercial PVA membrane in the dehydration of toluene by a pervaporation (PV) membrane system is studied in the present work. The results obtained indicate that increasing temperature in the range of 40 to 70 °C and reducing permeate pressure in the range of 1 to 10 mmHg increase memb...
متن کاملPorous Proton Exchange Membrane Based Zeolitic Imidazolate Framework-8 (ZIF-8)
Metal-organic frameworks (MOFs) are emerging material class for the past few years due to its tailorability characteristics for various applications. However, the research and development (R&D) of MOFs is still scarce for fuel cell system. This may be due to the several difficulties faced in selecting a good MOFs-based electrolyte, which consequently affects both proton conduction and methanol ...
متن کاملSharp separation of C2/C3 hydrocarbon mixtures by zeolitic imidazolate framework-8 (ZIF-8) membranes synthesized in aqueous solutions.
Exceptional high quality ZIF-8 membranes prepared through a novel seeded growth method in aqueous solutions at near room temperature exhibit excellent separation performance for C2/C3 hydrocarbon mixtures. The separation factors for mixtures of ethane/propane, ethylene/propylene and ethylene/propane are ∼80, ∼10 and ∼167, respectively.
متن کاملEnhanced Bioethanol Production in Batch Fermentation by Pervaporation Using a PDMS Membrane Bioreactor
The integration of batch fermentation and membrane-based pervaporation process in a membrane bioreactor (MBR) was studied to enhance bioethanol production compared to conventional batch fermentation operated at optimum condition. For this purpose, a laboratory-scale MBR system was designed and fabricated. Dense hydrophobic Polydimethylsiloxane (PDMS) membrane was used for pervaporation. For fer...
