Sustentabilidade energética do etanol de primeira geração no Brasil : uma releitura crítica de referenciais metodológicos
(Universidade Federal de São Carlos, 2017-02-01)
In the long run, all fossil energy, such as oil, natural gas, coal, and radioactive material, will run out. Within a horizon of one or two centuries, all energy must come from renewable sources. The concept of sustainable ...
Imobilização de lipases pela técnica CLEA para síntese de biodiesel em reator de fluxo em vórtice
(Universidade Federal de São Carlos, 2017-10-30)
Due to the heterogeneity of the vegetable oils used in the synthesis of biodiesel, they can be transformed more quickly using a mixture consisting of lipases with different activities and specificities instead of single ...
Estudo integrado das etapas de pré-tratamento e hidrólise enzimática da palha de cana-de-açúcar
(Universidade Federal de São Carlos, 2017-10-20)
The use of lignocellulosic biomass for ethanol production, such as, the sugarcane straw, suggests that additional steps should be included aiming the sugars release, that will be converted to ethanol via fermentative route. ...
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 ...
Modelos preditivos para equilíbrio de fases de misturas hidroalcoólicas multicomponentes presentes na concentração e desidratação de etanol de 1ª e 2ª geração
(Universidade Federal de São Carlos, 2017-06-30)
The production increase of the ethanol from sugarcane, ensuring energy and environmental viability, goes through the development of the step with highest energy consumption: the separation process in the distillation ...
Análise das propriedades de fluxo de diferentes tipos de açúcar
(Universidade Federal de São Carlos, 2017-02-22)
Various processes in food, pharmaceutical and chemical industries have to handle with solid particles at some point during their processes. From the manufacturing process to storage of these materials, interparticle forces ...
Monitoramento por espectroscopia dos compostos fenólicos e furaldeídos gerados no processamento de biomassa lignocelulósica
(Universidade Federal de São Carlos, 2017-02-20)
The major process challenge of the second-generation ethanol (2G) production is related
with characterization of hydrolyzate from lignocellulosic biomass, which often contains
high quantities of phenolic compounds and ...
