Journal ArticleDOI
Technologies for butanol recovery integrated with fermentations
TL;DR: In this article, five technologies for in-situ product recovery have been compared on the basis of design parameters and energy efficiency: stripping, adsorption, liquid-liquid extraction, pervaporation and membrane solvent extraction.
Journal ArticleDOI
Butanol recovery from fermentations by liquid-liquid extraction and membrane solvent extraction
W. J. Groot,H. S. Soedjak,P. B. Donck,R. G. J. M. van der Lans,K. Ch. A. M. Luyben,J. M. K. Timmer +5 more
TL;DR: In this paper, the authors evaluated the applicability of liquid-liquid extraction and membrane solvent extraction in butanol fermentations to increase the substrate conversion and found that a threefold increase in the substrate consumption could be achieved, in the continuous fermentation about 30% increase.
Journal ArticleDOI
In situ product recovery by adsorption in the butanol/isopropanol batch fermentation
W. J. Groot,K. Ch. A. M. Luyben +1 more
TL;DR: In this article, the butanol/isopropanol batch fermentation adsorption of alcohols can increase the substrate conversion, but fouling of adsorbants by cells and medium components is severe.
Journal ArticleDOI
Batch and continuous butanol fermentations with free cells: integration with product recovery by gas-stripping
TL;DR: In this paper, an external stripper was used as an apparatus for the butanol recovery, which led to an increase in the biomass concentration, resulting in a threefold increase in productivity.
Journal ArticleDOI
Continuous production of butanol from a glucose/xylose mixture with an immobilized cell system coupled to pervaporation
W. J. Groot,K. Ch. A. M. Luyben +1 more
TL;DR: With pervaporation for in-situ butanol recovery the complete conversion of a feed containing 60 kg/m3 of mixed sugars is achieved.
