Produção de hidrogênio e metano a patir de glicerol bruto e cultura mista em reatores anaeróbios de leito fluidizado termofílicos
(Universidade Federal de São Carlos, 2017-03-24)
The study aimed to evaluate the continuous production of hydrogen and methane under
thermophilic conditions (55 °C) using crude glycerol as substrate and mixed culture. The first
study aimed at the production of H2, and ...
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 ...
Catalisadores de Au suportados aplicados à oxidação preferencial do CO : influência da interação entre Au e Fe nos sítios ativos
(Universidade Federal de São Carlos, 2017-04-07)
New sources of clean energy have been studied, such as hydrogen (H2). Carbon monoxide, a subproduct of its production, poisons the fuel cell. To reach concentrations below 10 ppm, the addition of preferential CO oxidation ...
Avaliação do desempenho dos tratamentos das superfícies dos meios filtrantes submetidos à filtração por pulso de ar reverso
(Universidade Federal de São Carlos, 2017-03-31)
The objective of this work was to characterize different fibrous filters after filtration
and to evaluate the surface treatment performance of these materials during pulse jet filtration,
in the removal of micrometric ...
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

Controle de biorreator com base em modelo de fluxos metabólicos : sintonia das condições de microaeração para maximização da produção de etanol por S. cerevisiae
(Universidade Federal de São Carlos, 2017-02-24)
Biofuels are alternatives to fossil fuels, and bioethanol produced from corn and sugarcane is one of the main liquid biofuel currently used. To reach ethanol production maximum yield, it is important to use all fermentable ...
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 ...
