摘要
生物乙醇是一种很有前途的化石燃料替代品,但由于存在共沸点,从水中分离仍然具有挑战性。本研究研究了一种由聚二甲基硅氧烷(PDMS)选择层支撑在氧化锌纳米粒子修饰的聚砜(PSf)层上的渗透蒸发膜。优化后的渗透汽化膜在50℃下的通量为1014.45 g m−2 h−1,分离系数为3.96,PDMS为3 wt%, ZnO为1 wt%。超滤预处理对酵母和葡萄糖的杂质去除率分别达到100%和67%,显著提高了膜的性能和操作稳定性。这种集成超滤-渗透蒸发工艺为生物乙醇净化提供了一种高效的工艺。
Integrated ultrafiltration and pervaporation process using PDMS/ZnO-modified PSf nanohybrid membranes for enhanced bioethanol purification from fermentation broth
Bioethanol is a promising alternative to fossil fuels, but its separation from water remains challenging due to the presence of the azeotropic point. This study investigates a pervaporation membrane comprising a polydimethylsiloxane (PDMS) selective layer supported on a polysulfone (PSf) layer modified with ZnO nanoparticles. The optimized pervaporation membrane with 3 wt% PDMS and 1 wt% ZnO, achieved a stable flux of 1014.45 g m−2 h−1 and a separation factor of 3.96 at 50 °C. Pretreatment using ultrafiltration removed most of impurities reached 100 % and 67 % for yeast and glucose, respectively, significantly improving the membrane's performance and operational stability. This integrated ultrafiltration-pervaporation process offers an efficient process for bioethanol purification.
