Catalisadores de Pt suportados, obtidos pelo método solgel : efeito do cério na atividade e estabilidade nas reações de reforma do metano
(Universidade Federal de São Carlos, 2009-12-11)
The effect of Ce as a structural and electronic promoter on the activity and stability of Pt catalysts supported on Al2O3 for methane reforming reactions were investigated to elucidate the metal-support interaction. Pt/Al2O3 ...
Investigação do efeito de injeção de líquido por orifícios múltiplos na formação de gotas em um lavador Venturi
(Universidade Federal de São Carlos, 2009-02-20)
Venturi scrubbers are widely used in industrial plants in the cleaning of gases. In these scrubbers, the cleaning elements are the droplets formed at the injection of a liquid in the gas
containing pollutants. The droplets ...

Características temporais da concentração de material particulado na atmosfera da cidade de São Carlos - SP
(Universidade Federal de São Carlos, 2009-03-19)
The city of São Carlos, of medium size of São Paulo State, can be considered as representative of the Brazilian Southeast area, with agricultural activities practically equivalent to the industrial ones. As part of that ...
Precipitação do clavulanato de potássio a partir do ácido clavulânico presente no caldo de fermentação
(Universidade Federal de São Carlos, 2008-08-29)
Clavulanic acid is a potent inhibitor of many β-lactamase enzymes producing bacteria, which attribute bacterial resistant against cephalosporins and penicillins. The combination of CA with amoxicillin is the most ...
Fluidodinâmica de leitos fluidizados e vibrofluidizados operando com partículas planas
(Universidade Federal de São Carlos, 2009-03-12)
The use of fluidized beds as a unit operation for drying of particulate materials is common in industrial processes. However, most works published in the literature, focus the drying of uniform particles, in a narrow range ...
