Estudo do processo de cristalização de açúcar : modelagem e estratégias de controle.
(Universidade Federal de São Carlos, 2007-08-08)
Sugar cane can be considered one of the main crop in the state of São Paulo,
both for its contribution to the gross profits of the entire state harvest and the extent of the
agricultural land it occupies. Recent figures ...
Nanopartículas de Pt suportadas em Al2O3 e CeO2-Al2O3: síntese, caracterização e propriedades catalíticas para reforma do metano.
(Universidade Federal de São Carlos, 2007-03-16)
A new method to prepare Pt nanoparticles (NPs) dispersed on Al2O3 and CeO2-Al2O3
is described in this work. The Pt-NPs were used to prepare CeO2-Al2O3-supported Pt
nanocatalysts (Pt-NPs/Al2O3 and Pt-NPs/CeO2-Al2O3). The ...
Perovskitas La1-xSrxMnO3, suportadas em alumina e zircônia, aplicadas à combustão do metano
(Universidade Federal de São Carlos, 2007-08-28)
The total oxidation of the methane is an important environmental and industrial
reaction, mainly because it is extensively used in energy production and in the control
of gases emission to the atmosphere. With catalysts, ...
Caracterização metabólica e cinética do cultivo de três hibridomas para produção de imunoglobulinas com especificidade e antígenos eritrocitários para uso hemoterápico.
(Universidade Federal de São Carlos, 2007-03-30)
In the last two decades mammalian cell cultures have been broadly used for the
industrial production of pharmaceutical, proteins, in particular the monoclonal antibodies by
cultures of murine hybrid cells (hybridoma). The ...
Estudo da imobilização de celulase em géis de quitosana.
(Universidade Federal de São Carlos, 2007-01-29)
Cellulases are enzymes that catalyze the hydrolysis of cellulose producing glucose.
Immobilization and stabilization of these enzymes could improve enzymatic process making
it more attractive by reducing costs during their ...
Nanopartículas de Co suportadas em SiO2: síntese, caracterização e propriedades catalíticas para a reforma a vapor do etanol
(Universidade Federal de São Carlos, 2007-03-16)
Colloidal Co Nanoparticles (Co-NPs) were used to prepare supported Co catalysts. The Co-
NPs were obtained by thermal decomposition of the precursor Co2(CO)8 in the presence of
oleic acid and trioctylphosphine oxide ...
Avaliação da velocidade de cisalhamento média em biorreator convencional tipo tanque agitado e aerado
(Universidade Federal de São Carlos, 2007-03-12)
In biochemical processes, shear rate ( γ&) in the system is an important variable on design
and operation of bioreactors. Shear can result in damage to the cells and the microorganisms,
taking to the viability loss ...
Influência das condições operacionais na formação e remoção de tortas de filtração de gases
(Universidade Federal de São Carlos, 2007-03-30)
The present work aims to evaluate the influence of some operational variables on the filtration process and cake detachment, and also the patchy cleaning phenomenon. The studied conditions were maximum pressure drop, 20, ...
Catalisadores à base de Mo, NiMo e CoMo suportados sobre y-Alumina ou Al-MCM-41 - Avaliação na hidrodessulfurização do dibenzotiofeno
(Universidade Federal de São Carlos, 2007-04-13)
The effect of the γ Al2O3 synthesized by Sol-Gel method and Al-MCM-41 mesoporous molecular sieves used as supports in the preparation of Mo, NiMo and CoMo catalysts was studied. The activity and selectivity of the ...
Estudo do mecanismo eletroforético de coleta na filtração de aerossóis
(Universidade Federal de São Carlos, 2007-05-18)
Previous works have shown that the presence of electrostatic forces in particles significantly affect the performance of a filter, both increasing collection efficiency and reducing pressure drop. Recently, in the Environmental ...
