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 ...
Fração de filme líquido nas paredes de um lavador Venturi
(Universidade Federal de São Carlos, 2008-07-10)
The study of the liquid film in the walls of a Venturi scrubber was chosen as the target of this work for representing one of the important phenomena that influence the collection efficiency of the equipment. Such efficiency ...
Aplicação de técnicas de análise de imagens na quantificação da concentração celular no cultivo de células de inseto.
(Universidade Federal de São Carlos, 2004-04-26)
Paradoxally, in spite of the cellular concentration to be the most important variable
in a bioprocess, in practice is the less monitored as a consequence of the experimental
difficulty found in its quantification in an ...
Estudo cinético da produção de ácido clavulânico e cefamicina C por Streptomyces clavuligerus
(Universidade Federal de São Carlos, 2009-03-30)
Clavulanic acid and cephamycin C are ϐ-lactam compounds, an important group of drugs used in the treatment of several bacterial diseases, and are simultaneously produced by the bacteria Streptomyces clavuligerus. ...
Transformação de cicloexano e metilcicloexano sobre as zeólitas HMCM-22, HZSM-5 e HUSY rendimento e seletividade a hidrocarbonetos leves
(Universidade Federal de São Carlos, 2009-03-27)
In Brazil, the oil production with high naphthenic hydrocarbon (HC) content and the hard growing for the petrochemical market have led to the necessity to maximize the production of light HC (in special light olefins). The ...
Formação de mesoporos na síntese de zeólitas ZSM-5 via nanomoldagem avaliação no craqueamento de n-decano
(Universidade Federal de São Carlos, 2008-04-04)
The use of zeolites in the cracking of hydrocarbons is limited because the molecules higher than 0.74 nm do not diffuse in their micropores. In the other hand, molecular sieves as MCM-41, MCM-48 ou SBA-15, whose diameters ...
Catalisadores Cu-, Co- ou Fe-ZSM-5 caracterização e avaliação na redução de NO a N2 com hidrocarbonetos na presença ou ausência de vapor de água.
(Universidade Federal de São Carlos, 2005-03-04)
The minimization of the emissions of nitrogen oxides (NOx) in the atmosphere has been one of the great goals in the area of environmental
protection. Among the possible processes to treat the NOx, the selective catalytic ...
Estudo da transferência de calor e massa no processo de secagem em leito vibro-fluidizado.
(Universidade Federal de São Carlos, 2003-09-05)
Drying processes in fluidized and vibro-fluidized beds are nowadays being widely
investigated in the literature, because such beds offer many advantages over other types of
dryers. The purpose of this work is to contribute ...
Secagem de sementes de Arachis hipogae L. com capa protetora
(Universidade Federal de São Carlos, 2009-02-20)
Arachis hipogae L. peanut is an orthodox seed that must go through a drying process to become free from aflatoxin. The fruit is formed by a system made up by a nucleus and a resistant involucre that constitutes a heterogeneous ...
Comportamento da filtração de gases em meios filtrantes de celulose.
(Universidade Federal de São Carlos, 2006-09-15)
The present work aims to evaluate, through filtration process and cake detachment, the
behavior of two cellulose fiber filtering media with different air permeability values. The
powder material used was phosphatic ...
