Modelagem e otimização da fermentação alcoólica em batelada alimentada a baixa temperatura
(Universidade Federal de São Carlos, 2019-02-22)
The effect of product inhibition on yeast hinders the production of wine with ethanol concentration above 80.0 g L-1 (~10 °GL) in the industrial ethanol production process commonly performed at 34 °C. Lowering the fermentation ...
Catalisadores Ni-Fe/MgAl2O4 na reforma a vapor do etanol: influência da razão molar Ni/Fe nas propriedades catalíticas
(Universidade Federal de São Carlos, 2017-03-02)
The effect of iron incorporation on the catalytic properties of Ni / MgAl2O4 for the Ethanol Steam Reforming (ESR) was studied. Samples of different Fe/Ni molar ratios were prepared by wet impregnation of MgAl2O4, synthesized ...
Avaliação experimental de um ciclone adaptado com bocais pulverizadores de água
(Universidade Federal de São Carlos, 2018-02-19)
Brazil is a world leader in the production of sugar and ethanol by using sugar cane. Nonetheless, in order to supply the energy demands of this sector, the sugarcane bagasse is used as a fuel in boilers and its burning ...
Captura de CO2 de gases de combustão utilizando óxido de cálcio
(Universidade Federal de São Carlos, 2018-02-23)
Calcium oxide (CaO) based materials were prepared, characterized and subjected to cyclic carbonation and decomposition reactions in order to evaluate the carbon dioxide capture capacity (CO2) and the stability of the ...
Estratégias para a síntese de agregados reticulados porosos de lipase de pâncreas de porco com propriedades magnéticas
(Universidade Federal de São Carlos, 2019-02-28)
Cross-linked enzyme aggregates (CLEAs) is an immobilization technique that does not require solid support, allows the use of semi-purified enzymes and the biocatalyst show higher volumetric activity. However, they present ...
Análise e modelagem da síntese enzimática de galacto-oligossacarídeos
(Universidade Federal de São Carlos, 2016-03-31)
Galactooligosaccharides are indigestible oligosaccharides with recognized prebiotic capacity. They can be synthesized enzymatically from lactose-rich substrates using the β-galactosidase enzyme by means of a kinetically ...
