乙醇发酵过程存在明显的产物抑制现象,严重制约了乙醇产率的提高。乙醇发酵与产物分离的耦合可有效解决这一难题,目前乙醇发酵耦合产物分离的方法主要有乙醇气提发酵、乙醇真空发酵、乙醇吸附发酵、乙醇萃取发酵、乙醇膜分离发酵等。作者主要概述了各种乙醇发酵耦合产物分离方法的研究进展,并对今后乙醇发酵耦合产物分离研究开发提出了展望。
Ethanol fermentation process, there is a clear phenomenon of product inhibition, severely restricted the improvement of ethanol yield. The coupling between ethanol fermentation and product separation can effectively solve this problem. At present, the methods for separating ethanol-ethanol fermentation products are ethanol stripping fermentation, ethanol vacuum fermentation, ethanol adsorption fermentation, ethanol extraction fermentation and ethanol membrane separation fermentation. The author mainly summarizes the research progress of various methods for the separation of ethanol fermentation coupling products, and puts forward the prospect of future research on the separation of ethanol fermentation coupling products.
