Produção de enzimas pelo cocultivo de fungos filamentosos por fermentação em estado sólido e aplicação do meio integral na sacarificação da biomassa para obtenção de etanol celulósico
(Universidade Federal de São Carlos, 2016-03-01)
The use of a simplified consolidated bioprocess for the conversion of biomass using
enzymes produced in-house (integrated into the process of converting lignocellulosic
biomass) may enable significant increases in the ...
Catalisadores com estrutura do tipo perovskitas PrCo1-xNixO3 para produção de gás de síntese
(Universidade Federal de São Carlos, 2017-03-14)
Energy is an essential component for a country's development. Since Brazilians’ main energy source is the oil and it has limited reserves, an alternative is needed for a synthesis of fuels throughout other raw materials, ...

(Universidade Federal de São Carlos, 2016-05-02)
It is necessary knowing the characteristics of the filter media and how they influence the
filtration process to improve the filter media. With this, the aim of this study was to
characterize the filter media containing ...
Avaliação das condições hidrodinâmicas, de transferência de oxigênio e de cisalhamento em diferentes modelos e escalas de reatores pneumáticos
(Universidade Federal de São Carlos, 2016-04-26)
Due to the high capacity of oxygen transfer and versatility, pneumatic reactors have been
constantly used in bioprocesses. However, aiming to expand the use of these bioreactors in the industry, as well as increase the ...
Avaliação de parâmetros globais de desempenho de biorreatores pneumáticos através de fluidodinâmica computacional
(Universidade Federal de São Carlos, 2015-03-25)
Pneumatic bioreactors are devices free of moving parts which have the purpose
of converting raw materials in bio-products of commercial interest by the action of enzymes
or cells. They are promising in the biochemical ...

(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 ...
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 ...
