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 ...
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 ...
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 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 ...
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 ...
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 ...
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 ...
Preparação e caracterização de sílicas híbridas com surfactantes catiônicos
(Universidade Federal de São Carlos, 2018-02-16)
The silica with structure MCM-41 has a hexagonal mesoporous arrangement with one dimensional pore system. This silica as synthesized contains cations (usually the CTA+) in your pores and catalytic sites with basic character ...
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 ...
