Catalisadores Ni-Fe/MgAl2O4 na reforma a vapor do etanol: influência da razão molar Ni/Fe nas propriedades catalíticas
(Universidade Federal de São Carlos, 2017-03-02)
The effect of iron incorporation on the catalytic properties of Ni / MgAl2O4 for the Ethanol Steam Reforming (ESR) was studied. Samples of different Fe/Ni molar ratios were prepared by wet impregnation of MgAl2O4, synthesized ...
Partículas rugosas de sílica híbrida aplicadas na transesterificação catalítica
(Universidade Federal de São Carlos, 2019-03-15)
Heterogeneous catalysts are potentially responsible for reducing the cost of producing biodiesel, due to its reusability or use in continuous process. As-synthesized hybrid silicas, containing siloxy sites, can be used as ...
Métodos para caracterização de meios filtrantes contendo nanofibras
(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

(Universidade Federal de São Carlos, 2017-02-20)
The major process challenge of the second-generation ethanol (2G) production is related
with characterization of hydrolyzate from lignocellulosic biomass, which often contains
high quantities of phenolic compounds and ...
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 ...
