Recovery of acetone, butanol and ethanol from fermentation broth by gas stripping

Popis výsledku v původním jazyce

Butanol is a fermentation product of anaerobic solventogenic bacteria of the genus Clostridium. The acetone butanol ethanol (ABE) fermentation process by Clostridium is interesting for production of fuels from renewable resources. Unfortunately, economical production of butanol by fermentation is limited by end-product inhibition and uneconomical product recovery. The distillation was traditional technique used for product separation. Butanol have a higher boiling point than water, therefore this procedure uses up a lot of energy and it is very expensive, especially at low butanol concentrations. Therefore other separation ways are intensively and one of the preferred method for solvents recovery is gas stripping, nowadays. Our work was focused on gasstripping with nitrogen. Gas stripping was used in an integrated system i.e. the stripping took place directly in the bioreactor and thus it was tested as potential in situ product recovery technique. Freeze drying and adsorption on charc
