Contribuição ao estudo do desempenho de biorreatores airlift de circulação interna: análise das condições operacionais e da geometria do equipamento
(Universidade Federal de São Carlos, 2018-04-26)
The high oxygen transfer capacity associated with low energy consumption have made the airlift bioreactor an important equipment to be used in bioprocesses, with the performance of these devices being strongly dependent ...
Aplicação do método de lattice Boltzmann na simulação de meios filtrantes : implementação de códigos para geração do domínio de cálculo e condição de contorno de escorregamento
(Universidade Federal de São Carlos, 2018-03-19)
Many studies have been carried out to find the best operating point for filter media, and the mathematical modeling and simulation are becoming a important tool. In this work, a code was built to generate geometric models ...
Avaliação de meios filtrantes para filtro de mangas com sistema de limpeza de jato de ar pulsante do processo de despoeiramento secundário da aciaria de uma indústria siderúrgica
(Universidade Federal de São Carlos, 2018-03-01)
Nowadays, in addition to complying with the emission limits determined by the authorities, some companies seek to minimize their operating costs. In order to achieve this, they must choose a proper material for the filter ...
Modelagem fenomenológica da síntese enzimática de biodiesel etanólico utilizando lipase solúvel
(Universidade Federal de São Carlos, 2018-03-27)
The kinetics study of the synthesis of ethyl biodiesel allows a deeper understanding of the enzymatic process, providing an important tool for process design, optimization and control. Most of the models proposed in the ...
Partículas rugosas de sílica híbrida aplicadas na transesterificação catalítica
(Universidade Federal de São Carlos, 2019-03-15)
Heterogeneous catalysts are potentially responsible for reducing the cost of producing biodiesel, due to its reusability or use in continuous process. As-synthesized hybrid silicas, containing siloxy sites, can be used as ...
Análise e modelagem da síntese enzimática de galacto-oligossacarídeos
(Universidade Federal de São Carlos, 2016-03-31)
Galactooligosaccharides are indigestible oligosaccharides with recognized prebiotic capacity. They can be synthesized enzymatically from lactose-rich substrates using the β-galactosidase enzyme by means of a kinetically ...
