摘要

本研究考察了纳米膜反应器在以菜籽油为原料生产生物柴油的碱催化剂酯交换过程中的作用。利用聚偏氟乙烯和偏氟乙烯与四氟乙烯共聚物制备了多孔电纺丝纳米膜。聚合物膜的结构允许它被动过滤生产的粗生物柴油，同时保留甘油和副产品。脂肪酸甲酯（FAME）含量最高可达99%左右，重现性高，理想的酯交换条件为65℃，甲醇/油质量比为4:1，反应时间为65 min。所制得的FAME满足en14214的关键要求。经过4个制备循环后，产物流中没有甘油，说明纳米膜可以在反应介质中保持甘油。

Electrospun Nanomembrane-Assisted Transesterification for Biodiesel Production

The study examines how well a nanomembrane reactor functions in the base catalyst transesterification process to produce biodiesel with rapeseed oil as the feedstock. The fabrication of a porous electrospun nanomembrane was achieved through the utilization of poly(vinylidene fluoride) and a copolymer of vinylidene fluoride with tetrafluoroethylene. The polymeric membrane’s structure allowed it to passively filter the crude biodiesel produced while retaining the glycerol and byproducts. With the maximum fatty acid methyl esters (FAME) content of about 99% and high reproducibility, the ideal transesterification conditions were found at 65 °C and a 4:1 methanol/oil weight ratio for 65 min. The FAME produced satisfied the key requirements of EN 14214. After four preparation cycles, there was no glycerol in the product stream, indicating that the nanomembrane could hold the glycerol in the reaction medium.
