The pervaporation separation of organic compounds from acetone-butanol-ethanol (ABE) fermentation model solutions was studied using activated carbon (AC) nanoparticle-poly (dimethylsiloxane) (PDMS) mixed matrix membranes (MMM). The effects of the operating conditions and nanoparticle loading content on the membrane performance have been investigated. While the separation factor increased continuously, with an increase in the concentration of nanoparticles, the total flux reached a maximum in the MMM with 8 wt % nanoparticle loading in PDMS. Both the separation factor for ABE and the total permeation flux more than doubled for the MMM in comparison to those of neat PDMS membranes prepared in this study.
使用活性炭（AC）纳米颗粒-聚二甲基硅氧烷（PDMS）混合基质膜（MMM）研究了从丙酮-丁醇-乙醇（ABE）发酵模型溶液中对有机化合物进行渗透汽化分离。研究了操作条件和纳米颗粒负载量对膜性能的影响。随着纳米颗粒浓度的增加，分离因子持续增加，而在PDMS中纳米颗粒负载量为8 wt%的MMM中，总通量达到最大值。与本研究制备的纯PDMS膜相比，MMM的ABE分离因子和总渗透通量均增加了一倍以上。
