Biobutanol is known for its potential as a biofuel and for having various other industrial applications. However, technical and economic constraints still restrict its commercial application. Biobutanol is produced via acetone, butanol, and ethanol (ABE) fermentation, in which acetone and ethanol are also produced, mainly by Clostridium sp.; however, it is toxic to the cells. Efforts have been made to improve the process by separating butanol from the fermentation broth. This work presents an overview of the main processes reported in ABE separation in the literature, focusing on the pervaporation approach. Some of the latest developments in the field are stated, aiming at comparing the separation processes.

丙酮、丁醇、乙醇发酵下游丁醇分离的进展

生物丁醇以其作为生物燃料的潜力和其他各种工业应用而闻名。然而,技术和经济上的限制仍然限制了它的商业应用。生物丁醇是通过丙酮、丁醇和乙醇 (ABE) 发酵生产的,其中还生产丙酮和乙醇,主要是梭状芽孢杆菌;但是,它对细胞有毒。已经努力通过从发酵液中分离丁醇来改进该工艺。这项工作概述了文献中报道的 ABE 分离的主要过程,重点是全蒸发方法。陈述了该领域的一些最新发展,旨在比较分离过程。
