Análise do desempenho do leito vibrofluidizado na secagem de pasta
(Universidade Federal de São Carlos, 2017-05-05)
The agitation promoted by the vibrofluidized bed allows the incorporation of several unitary operations such as granulation, coating of particle, drying of grains, and the drying of pasty materials. However, it is necessary ...
Engenharia de biocatalisadores aplicada à síntese de CLEAs para a aplicação na conversão multienzimática de sacarose à ácido glucônico e xarope de frutose
(Universidade Federal de São Carlos, 2017-02-17)
Sugarcane sugar (sucrose) is a raw material produced in abundance in Brazil; it is very attractive to produce high added-value products. Gluconic acid (GA) can be obtained by multienzymatic conversion of sucrose, using ...
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 ...
Secagem de materiais pastosos e granulares no leito de jorro mecânico e convencional
(Universidade Federal de São Carlos, 2017-06-02)
This study had the objective to assess the behavior of a mechanically spouted bed compared to a conventional spouted bed through attrition of particulate matter, thermal and mass analysis during water evaporation and through ...
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 ...
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 ...
Desenvolvimento de técnica de cultivo para produção de células tumorais em forma de agregados em biorreator de vórtices de Taylor
(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 ...
