Estudo experimental e numérico da fluidodinâmica e das transferências de calor e massa em um leito de jorro contínuo: uso da técnica CFD
(Universidade Federal de São Carlos, 2010-05-10)
In this work, the transport phenomena, which occur during the drying operation in a continuous spouted bed, are evaluated through experimental data and CFD simulations. Thus, this thesis was divided into three main parts: ...
Purificação do ácido clavulânico por processo de filtração tangencial, extração por sistema de duas fases aquosas e re-extração com resina de troca iônica
(Universidade Federal de São Carlos, 2010-06-09)
Clavulanic acid is a β-lactam substance with low antibiotic activity. Nonetheless, it is an important medicine which acts as a potent β-lactamase inhibitor. These enzymes catalyze the hydrolysis of β-lactam ...
Produção de cefamicina C por Streptomyces clavuligerus em batelada e batelada alimentada
(Universidade Federal de São Carlos, 2010-03-31)
Cephamycin C (CephC) is a natural antibiotic produced by Streptomyces clavuligerus that presents β-lactamases resistance, enzymes that clives β-lactam of antibiotics. The aim of present work was study cephamycin ...
Estudo de catalisadores de cobre suportados para a reação de oxidação preferencial do CO
(Universidade Federal de São Carlos, 2010-06-30)
The CO preferential oxidation reaction (PROX-CO) has been widely studied in last few years. Aiming H2 purification for proton-exchange membrane cells (PEMFC) use, the main role of the PROX-CO reaction should be reduce the ...
Avaliação do processo de tratamento biológico de águas residuárias sanitária e industrial em sistema combinado com reator biológico de contato seguido de filtro aerado submerso
(Universidade Federal de São Carlos, 2010-02-22)
This study presents the operational results of a pilot wastewater treatment plant. The assays were carried out in two phases: Phase 1 involved the operation of a rotating biological contactor (RBC), while Phase 2 involved ...
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 ...
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 ...
