Extraction of sunflower oil using ethanol as solvent
(Elsevier, 2016-01-22)
The ethanolic extraction of oil from sunflower collets was studied and compared with previous data where hexane was used as extraction solvent. First, the extractive power of ethanol was determined by Soxhlet. It gave a ...
Estudo da produção de etanol de sacarose por fermentação extrativa utilizando arraste com dióxido de carbono
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2016-04-18)
The ethanol accumulated in the broth during fermentation is the main component toxic to
yeast, causing slower yeast growth and decreased ethanol production. One way of overcoming
this inhibition effect is to use extractive ...
