Otimização superestrutural de biorrefinaria de cana-de-açúcar com hidrólise e gaseificação da biomassa vegetal e biodigestão da vinhaça e do licor de pentoses
(Universidade Federal de São Carlos, 2018-08-20)
The production of ethanol in sugarcane biorefineries generates large amounts of by-products such as straw, bagasse and vinasse. The objective of this work was to develop and implement a tool for the analysis of investments ...
Catalisadores Pt/Al2O3 e CeO2/Pt/Al2O3 aplicados à reação deslocamento gás-água: efeito da composição nas propriedades estruturais e catalíticas
(Universidade Federal de São Carlos, 2018-08-17)
Alumina-supported platinum catalysts were synthesized via conventional impregnation varying the metal contents (0.3 to 2% Pt; 6 to 20% Ce, m / m) and the Pt precursors (H2PtCl6 and [Pt(NH3)4] (NO3)2), were evaluated for ...
Estratégias para obtenção de compósitos fertilizantes via solubilização biológica de minerais
(Universidade Federal de São Carlos, 2018-03-27)
Phosphate fertilizers are widely used to improve agricultural productivity. However, the process of producing these fertilizers involves high costs and can cause environmental damage. The application of phosphate solubilising ...
Otimização do controle do oxigênio dissolvido em biorreator airlift pressurizado: aplicação em cultivos de Escherichia coli recombinante
(Universidade Federal de São Carlos, 2018-01-12)
A wide variety of industrial and therapeutic proteins is synthetized by genetically modified Escherichia coli, which is ease to cultivate and manipulate and also well characterized. However, there are only few studies ...
Catalisadores magnéticos à base de ferritas de Co ou Zn e de heteroestruturas TiO2/Ferrita – Avaliação na degradação fotocatalítica de lignina
(Universidade Federal de São Carlos, 2018-05-30)
Vinasse derived from beverage industry represents a serious environmental risk if not properly treated, mainly attributable to the presence of organic macromolecules with complex structure and composition, the recalcitrant ...
Integração energética de biorrefinarias de cana-de-açúcar com operação multiperiódica
(Universidade Federal de São Carlos, 2018-01-16)
Brazil has a great importance as biofuels producer, especially of ethanol from sugarcane. The bagasse, a byproduct of sugarcane biorefineries, can be used to generate electricity and produce second generation
ethanol. ...
Secagem de cevada: análise da anatomia e do meio de transporte
(Universidade Federal de São Carlos, 2018-03-23)
Despite the recent motivations for application in the food industry, the characterization of polished barley grains is still scarce in the literature. In this way, the objective of this work was the experimental analysis ...
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 ...
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 ...
Cristalização e separação de KCI a partir de carnalita : síntese de processo, simulação e viabilidade econômica
(Universidade Federal de São Carlos, 2018-02-21)
Due to the increasing demand for potassium in Brazil, it is feasible to exploit carnallite in order to supply part of the national need for this alkali metal, whose reserves of raw material - in this case sylvite - are ...
