Redução de NO com CO sobre catalisadores de CuO, Fe2O3 e CuO-Fe2O3 suportados em TiO2, ZrO2 e TiO2-ZrO2 - efeito do vapor de água na atividade e seletividade a N2
(Universidade Federal de São Carlos, 2013-04-26)
The combustion of petroleum fuels produces large emissions of NOX, SOX and other strong atmospheric pollutants. The abatement of NOX can be achieved by the nonselective catalytic reduction of NO with CO, for that, supported ...
Reações cíclicas de oxidação e redução de materiais a base de Ni para geração de hidrogênio
(Universidade Federal de São Carlos, 2017-04-06)
Hydrogen (H2) is used in several industrial processes, including ammonia production and petroleum refining. Commercially, most of the H2 produced is from methane steam reforming. Although well established industrially, ...
Produção de etanol empregando leveduras convencionais e termotolerantes
(Universidade Federal de São Carlos, 2017-02-23)
To attend the increase in Brazilian ethanol consumption and exportation, and also to comply with the goals established in the COP 21 and Quioto protocol, it will be necessary to increase the ethanol production in the next ...
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 ...
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 ...
Recuperação de lipase BTL-2 de Bacillus thermocatenulatus produzida em Escherichia coli recombinante empregando suportes magnéticos
(Universidade Federal de São Carlos, 2016-04-06)
Magnetic supports have gained attention because the magnetic separation is easy, has low cost and high efficiency. Moreover, it allows the purification and immobilization of a biomolecules in single step. Lipases are ...

(Universidade Federal de São Carlos, 2017-02-24)
Cultivation of animal cell is gaining great interest in various biotechnological
applications. The growth of cancer cells in particular has been used for cancer -fighting drugs
tests. The major obstacle faced in the ...
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 ...
Escherichia coli detoxificada como plataforma para produção de proteína recombinante A de superfície de pneumococo
(Universidade Federal de São Carlos, 2018-03-02)
One of the main challenges in the therapeutic proteins production using Escherichia coli is to obtain a high purity product. Among the main contaminants (nucleic acids, polysaccharides and contaminating proteins) ...
