Síntese de celulose bacteriana a partir de resíduos lignocelulósicos via evolução adaptativa
(Universidade Federal de São Carlos, 2019-05-21)
Bacterial cellulose (BC) is produced mainly by the Komagataeibacter genus. BC is a biopolymer free of impurities, built from the interlacing of cellulose nanofibers, which presents remarkable properties, such as: high ...
Influência das cargas eletrostáticas na filtração de partículas em meios filtrantes de fibra de vidro
(Universidade Federal de São Carlos, 2019-04-30)
Currently, in the gas filtration processes, the presence of electrostatic charges in the particles has been shown to contribute positively to the performance of the filter medium. Due to its high competitiveness in the ...
Avaliação por CFD da fluidodinâmica e da transferência de calor em leitos de jorro para diferentes ângulos da base cônica
(Universidade Federal de São Carlos, 2019-02-27)
The spouted bed is an equipment that provides fluid-particle contact due to the cyclic movement of solids in its interior, which results in high rates of heat and mass transfer between phases. The spouted bed is used in ...
Avaliação da produção de açúcar utilizando reconciliação de dados, estatística multivariada e modelagem fenomenológica da cristalização
(Universidade Federal de São Carlos, 2019-02-25)
Sugarcane, grown in more than a hundred countries, is one of the major crops of the world. Brazil is the world’s largest producer. Sugarcane industries are constantly seeking to reduce the industrial process losses, to ...
Fermentação alcoólica: desenvolvimento de metodologia para o cálculo de eficiência e modelagem por redes neurais de unidade de fermentação industrial
(Universidade Federal de São Carlos, 2019-02-21)
The search for alternative sources of fuel, economically and environmentally viable, that could replace fossil fuels has increased in the last years. Brazil occupies a prominent position regarding the pioneering development ...
Análise do escoamento em um ciclone adaptado com bicos aspersores de água utilizando fluidodinâmica computacional (CFD)
(Universidade Federal de São Carlos, 2019-02-25)
Cyclonic separators are widely used in industries for gas-solid separation process. Its low cost in building, operating and maintenance, as well as the ability to operate at high temperatures and pressures, makes it a good ...
Efeito do tamanho de partículas de Cu nas propriedades estruturais e eletrônicas e suas correlações com propriedades catalíticas na desidrogenação do etanol em Cu/SiO2
(Universidade Federal de São Carlos, 2019-03-08)
Metal nanoparticles may exhibit distinct catalytic behavior when there are particle size variations at nanometric scale. Cu nanoparticles supported on SiO2 and CAB-O-SIL® were synthesized with different metal loadings by ...
Modelagem e otimização da fermentação alcoólica em batelada alimentada a baixa temperatura
(Universidade Federal de São Carlos, 2019-02-22)
The effect of product inhibition on yeast hinders the production of wine with ethanol concentration above 80.0 g L-1 (~10 °GL) in the industrial ethanol production process commonly performed at 34 °C. Lowering the fermentation ...
Estratégias para a síntese de agregados reticulados porosos de lipase de pâncreas de porco com propriedades magnéticas
(Universidade Federal de São Carlos, 2019-02-28)
Cross-linked enzyme aggregates (CLEAs) is an immobilization technique that does not require solid support, allows the use of semi-purified enzymes and the biocatalyst show higher volumetric activity. However, they present ...
