Controle nebuloso ("fuzzy”) aplicado à combustão em caldeiras a bagaço de cana
(Universidade Federal de São Carlos, 2018-04-26)
In the sugarcane industry, boilers are widely used for cogeneration. This term designates the simultaneous generation of more than one type of energy, namely thermal and electrical, from the same fuel source. This industry ...
Reforma a vapor do etanol sobre catalisadores de Co - Ni/MgAl2O4: propriedades estruturais e catalíticas em função da temperatura de reação
(Universidade Federal de São Carlos, 2016-08-05)
This thesis studied the effect of Co addition to Ni-based catalysts, focused on electronic and structural modification, as well as how these changes interfere on the catalytic properties, like reaction pathway and carbon ...
Integração energética de biorrefinarias de cana-de-açúcar com operação multiperiódica
(Universidade Federal de São Carlos, 2018-01-16)
Brazil has a great importance as biofuels producer, especially of ethanol from sugarcane. The bagasse, a byproduct of sugarcane biorefineries, can be used to generate electricity and produce second generation
ethanol. ...
Desenvolvimento de sistema nebuloso (fuzzy) para controle do oxigênio dissolvido no cultivo de escherichia coli para expressão de proteínas recombinantes
(Universidade Federal de São Carlos, 2018-02-26)
One very important bioprocess is the cultivation of recombinant E. coli for expression of heterologous proteins. For this, High Cell Density Culture is one of the most widely used technique. Although it results in cell ...
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 ...
Secagem de cevada: análise da anatomia e do meio de transporte
(Universidade Federal de São Carlos, 2018-03-23)
Despite the recent motivations for application in the food industry, the characterization of polished barley grains is still scarce in the literature. In this way, the objective of this work was the experimental analysis ...
Otimização do controle do oxigênio dissolvido em biorreator airlift pressurizado: aplicação em cultivos de Escherichia coli recombinante
(Universidade Federal de São Carlos, 2018-01-12)
A wide variety of industrial and therapeutic proteins is synthetized by genetically modified Escherichia coli, which is ease to cultivate and manipulate and also well characterized. However, there are only few studies ...
Parâmetros cinéticos da cristalização de sacarose em diferentes escalas
(Universidade Federal de São Carlos, 2018-03-07)
This work aims to determine kinetic parameters capable of describing the crystallization of sucrose using bench scale and pilot scale reactors. Sucrose was chosen because it is a very important product for Brazil, which ...
Estudo da produção de etanol de sacarose por fermentação extrativa utilizando arraste com dióxido de carbono
(Universidade Federal de 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 ...
Otimização superestrutural de biorrefinaria de cana-de-açúcar com hidrólise e gaseificação da biomassa vegetal e biodigestão da vinhaça e do licor de pentoses
(Universidade Federal de São Carlos, 2018-08-20)
The production of ethanol in sugarcane biorefineries generates large amounts of by-products such as straw, bagasse and vinasse. The objective of this work was to develop and implement a tool for the analysis of investments ...
