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 ...
Catalisadores derivados de óxidos do tipo perovskita LaMO3, LaMFeO3 e LaMO3/γ-Al2O3 (M = Co, Ni ou Fe) aplicados à reforma a vapor de etanol
(Universidade Federal de São Carlos, 2014-07-30)
The hydrogen production has been extensively studied as a clean and powerful energy source, indicating that in the future hydrogen will became a key component for the global energy production, since burning fossil fuels, ...
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 ...
Determinação da cinética de cristalização em diferentes escalas visando o projeto de cristalizador em batelada utilizando o sistema monopentaeritritol-água como modelo
(Universidade Federal de São Carlos, 2007-05-04)
Previous studies on crystallization as an industrial process have been
frequently limited to just one aspect of the process. They usually study
parameter optimization or a method for monitoring solution or suspension,
...
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 ...
Estudo da produção de etanol de sacarose por fermentação extrativa utilizando arraste com dióxido de carbono
(Universidade Federal de São Carlos, 2016-04-18)
The ethanol accumulated in the broth during fermentation is the main component toxic to
yeast, causing slower yeast growth and decreased ethanol production. One way of overcoming
this inhibition effect is to use extractive ...
Análise do efeito das condições operacionais e características geométricas do leito de jorro na secagem de pastas
(Universidade Federal de São Carlos, 2015-07-06)
In this present work, the fluidynamic and drying process of paste in a spouted
bed was analyzed. The experiments were conducted using polyethylene particles of 4.38 mm
of diameter and 930.5 ± 0.3 kg/m3 of specific mass ...
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 ...
