Filtração de gases: estudo da deposição de diferentes tortas de filtração em diferentes meios filtrantes
(Universidade Federal de São Carlos, 2006-06-19)
The particle retention inside a filter medium, after cleaning, significantly improves the
initial pressure drop during the subsequent cycle, that is, the residual pressure drop.
However, the way as these particles ...
Contribuições ao estudo da secagem em um leito pneumático vertical
(Universidade Federal de São Carlos, 2004-03-30)
Pneumatic dryers are widely applied in industry, mainly because the transport of particulate material can be performed simultaneously with heating and drying operations. However, the design of such equipment is still based ...
Validação da simulação dinâmica das etapas de evaporação e cristalização da produção de açúcar com dados obtidos em plantas industriais.
(Universidade Federal de São Carlos, 2004-06-23)
The central area of the State of São Paulo, Brazil, where the city of São Carlos is located, is one of the largest world producers of alcohol and granulated sugar from sugar cane. As the market become more competitive, the ...
Isomerização do N-hexano sobre catalisadores Pt-Ni suportados na zeólita H-BEA nanocristalina
(Universidade Federal de São Carlos, 2008-11-11)
This work had as a goal to investigate the main factors that explain the highest activity of zeolite Beta in relation to the other zeolitic structures, using the n-hexane isomerization as a criterion. With this goal, in ...
Estudo do efeito da adição de Au, Pd e Pt em catalisadores Cu/CeO2 aplicados à reação de deslocamento gás-água a baixa temperatura
(Universidade Federal de São Carlos, 2008-07-02)
Cu/CeO2 catalysts doped with Au, Pd or Pt (WGSR) were prepared and applied in water gas shift reaction. The CeO2 support was prepared by four different way: urea co-precipitation-gelation (CeO2-UGC), hydrothermal method ...
Abordagem estatística e computacional na otimização de meios de cultura para produção de antibióticos: o caso da cefalosporina C.
(Universidade Federal de São Carlos, 2003-10-10)
The scope of the current work was to investigate the effect of glucose, amonium acetate, DL-methionine, phosphorus, oleic acid and salt solution on the maximum specific growth rate (µmax), as well as the effect of sucrose ...
Avaliação de aspectos fluidodinâmicos e da transferência de calor em leito fixo com escoamento gás-líquido concorrente vertical.
(Universidade Federal de São Carlos, 2004-03-02)
In this work, the heat transfer in packed bed with gas-liquid co-current downflow and upflow was investigated. The influence of hydrodynamic factors, of the size and shape of particles, of the length of the thermal section ...
Perovskitas contendo lantânio, ferro e cobalto - melhoramento de propriedades texturais via síntese por nanomoldagem e avaliação como catalisadores na redução de NO com CO
(Universidade Federal de São Carlos, 2008-10-20)
Mixed oxides with perovskite structure have high potential as catalysts in gas depollution processes and particularly in the abatement of nitrogen oxides (NOx). Such solids could be considered as a promising alternative ...
Diferentes meios de cultivo e condições operacionais na produção de penicilina G acilase por Bacillus megaterium.
(Universidade Federal de São Carlos, 2007-08-16)
Penicillin G acylase (PGA) is an important enzyme for industry, used to produce
aminopenicillanic acid, a key intermediate in the synthesis of ampicillin, among other betalatam
antibiotics. The production of this enzyme ...
Reator enzimático de membrana para proteólise de soro de queijo, visando à produção de concentrado protéico com baixo teor de fenilalanina
(Universidade Federal de São Carlos, 2007-12-07)
Enzymatic hydrolyzed proteins present some advantages over the pool of
amino acids obtained after a chemical hydrolysis: lower osmolality (easier absorption by the
organism) and better sensorial characteristics. The removal ...
