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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Assesment of alternative routes for sugarcane-based ethanol recovery: exergy and economic analysis
(Universidade Federal de São Carlos, 2018-02-28)
The aim of this thesis was to develop a methodological approach that can systematically guide process simulation for better understanding of bioethanol production process. In the present work, the ethanol production process ...
Estudo de embriões de zeólitas como catalisadores básicos na condensação de Knoevenagel
(Universidade Federal de São Carlos, 2018-03-29)
The accessibility to the catalytic sites is one of the main objectives involving the development of heterogeneous catalysts. In this context, several researches seek the reduction of crystal diameters or the creation of ...
