Inferência de variáveis do processo de produção de penicilina G acilase por Bacillus megaterium ATCC-14945.
(Universidade Federal de São Carlos, 2003-07-27)
The enzyme penicillin G acylase (E.C.3.5.1.11) is used in the production of 6-aminopenicillanic acid (6-APA) and 7-aminocephalosporinic acid (7-ACA), which are key intermediates for the production of β-lactam antibiotics. ...
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 ...
Estudo da preparação e das propriedades estruturais de catalisadores para a transformação do metano em gás de síntese e hidrocarbonetos
(Universidade Federal de São Carlos, 2010-06-15)
Pt catalysts supported on CeO2-La2O3-Al2O3, with different mixed oxide compositions, and CeO2-ZrO2-Al2O3, prepared using three different routes, were synthesized by sol gel technique. The samples were characterized using ...
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 ...
Análise da secagem de pastas em leito de jorro
(Universidade Federal de São Carlos, 2009-03-09)
The objective of this Doctoral Thesis was to analyse the fluidynamics and the heat and mass transfer of paste drying in a spouted bed under transient operation and to obtain
detailed experimental data on the disturbed ...
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 ...
Síntese e avaliação de sílica tipo M41S contendo cátions CTA em transesterificação catalítica
(Universidade Federal de São Carlos, 2010-08-13)
The investments in the biofuel production have increased a lot in the last years mainly because of smaller damages they cause to the environment in comparison with the derived conventional petroleum fuels. The reaction of ...
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 ...
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 ...
