Efeito do teor de CeO2 em catalisadores de Pt/CeO2-Al2O3 para as reações de oxidação parcial e reforma do metano.
(Universidade Federal de São Carlos, 2005-03-10)
The effect of CeO2 loading in Pt/CeO2-Al2O3 catalysts was investigated. Pt
catalysts supported on mixed CeO2-Al2O3 carriers with different CeO2 loading 1,
3, 6, 12, 20 wt.% were prepared by incipient wetness impregnation ...
Propriedades estruturais e eletroquímicas de espinélios de lítio e manganês dopados para uso em baterias de lítio.
(Universidade Federal de São Carlos, 2005-09-01)
The spinels investigated in the present work
were obtained by solid state reaction at 750 ºC for 72 h among the precursors
ε-MnO2, LiOH and the respective oxides/salt of the doping ions. In order to control
the particles ...
Material particulado atmosférico na cidade de São Carlos- SP: quantificação e identificação de fontes.
(Universidade Federal de São Carlos, 2005-05-05)
In the present work, breathable particulate matter (PM10) concentration was measured in their fine (PM2.5-10) and ultra-fine (MP2.5) fractions, in the municipal district of São Carlos. The samplings were carried out from ...
Determinação da carga eletrostática em aerossóis e seu efeito na filtração de gases.
(Universidade Federal de São Carlos, 2005-05-06)
It has been shown that the presence of electrostatic charges in particles affects
significantly the performance of a filter, both increasing collection efficiency and reducing
pressure drop. The aim of the present work is ...
Estudo do desempenho de um precipitador eletrostático operando na captura de partículas submicrométricas e nanométricas.
(Universidade Federal de São Carlos, 2005-05-24)
The removal of submicron particles from gaseous streams is becoming an
increasingly important operation, both in industrial (nanotechnology) as well as in
occupational (inhalation of particula te matter) applications. Among ...
Contribuição ao estudo de controle plantwinde: controle indireto e coordenação de controladores descentralizados.
(Universidade Federal de São Carlos, 2005-03-28)
The design of plantwide control systems has received increasing attention in the last years. The modern chemical plants usually consist of hundreds of
interconnected elementary processes and unit operations (large scale ...
