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 ...
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 ...
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 ...
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 força de adesão de tortas de filtração de gases em diferentes condições operacionais
(Universidade Federal de São Carlos, 2010-03-08)
Gas filtration is one of the most important methods used in gas-solid separation. During a filtration process, a gas containing an amount of solid particles passes through a porous filter medium which retains the particles. ...
Modelo de contribuições de grupos aplicado a reações para a formação do biodiesel
(Universidade Federal de São Carlos, 2010-02-23)
The interest in biofuels has increased substantially in recent years due, mainly, to reduced damage to the environment compared to conventional fuels derived from petroleum. Accordingly, biodiesel has been studied by ...
Estudo da cristalização da frutose em diferentes meios
(Universidade Federal de São Carlos, 2010-03-09)
The phenomena of fructose crystal nucleation and growth in different media, and its water and ethanol/water solubility curves, which were the base of this process, were studied through the fructose crystallization process. ...
Síntese e caracterização de nanopartículas de TiO2 pelo método do precursor polimérico
(Universidade Federal de São Carlos, 2010-03-26)
Currently, scientific research in the field of nanotechnology has attracted growing interest because of its several applications, either through design of new products, materials characterization, production and application ...
