Title:
METHOD AND DEVICE FOR PRODUCING BUTANOL BY FERMENTATION COUPLING AND SEPARATION AND PURIFICATION
Document Type and Number:
WIPO Patent Application WO/2017/214873
Kind Code:
A1
Abstract:
Provided is a method for separating and purifying butanol, acetone and ethanol or purifying butanol by fermentation coupling, comprising the following steps: 1) fermenting using an acetone and butanol-producing bacteria to obtain butanol, acetone and ethanol or using a butanol-producing bacteria to obtain butanol; and 2) separating and purifying butanol, acetone and ethanol on-line or purifying butanol from the fermentation broth by using a vaporization permeation method. The method of the present invention improves the production and separation and thepurification efficiency of butanol, acetone and ethanol or butanol.
