Estudo do pré-tratamento hidrotérmico e hidrólise enzimática da palha de cana-de-açúcar
(Universidade Federal de São Carlos, 2016-04-08)
The complex cell wall structure of lignocellulosic biomass makes pretreatment one of the most
relevant 2G ethanol production process steps due to the difficulty of hydrolyzing lignocellulose
to fermentable sugars and the ...
Produção de sulfato de potássio a partir de cloreto de potássio e sulfato de amônio : estudos de equilíbrio sólido-líquido e desenvolvimento de processo
(Universidade Federal de São Carlos, 2016-02-29)
Potassium is one of the basic nutrients for plants and their concentration in the soil is
insufficient to produce high quality crops, so it should be an essential component in the
composition of fertilizers. Fertilizers ...
Lipase “whole-cell” de Streptomyces clavuligerus : produção, caracterização e aplicação em meio orgânico
(Universidade Federal de São Carlos, 2016-08-25)
Cell-associated lipases have been considered biocatalysts economically advantageous because
they are produced at low cost, avoiding further recovery or purification steps. Few studies
regarding Streptomyces clavuligerus ...
Estudo do metabolismo de Salmonella typhimurium : da abordagem tradicional à análise dos fluxos metabólicos
(Universidade Federal de São Carlos, 2015-08-27)
The genus Salmonella spp. has been extensively investigated because these
bacteria are important pathogens that frequently cause severe diseases and gastrointestinal
infections in humans and animals. Moreover, in recent ...
Oxidação de CO sobre catalisadores de Co e/ou Mn modificados com Mo e suportados em SBA-15 – Efeito do método de preparação e da presença de vapor de água e dióxido de enxofre na atividade catalítica
(Universidade Federal de São Carlos, 2016-08-25)
The increasing demand for oil and oil derived products contributed to the alarming increase in the gaseous pollutants emissions in general and mainly contributed to the increase in carbon monoxide (CO) emissions in the ...
Síntese da zeólita Beta usando planejamento experimental e emprego na isomerização do n-hexano
(Universidade Federal de São Carlos, 2012-09-14)
This work aimed to apply the Design Of Experiment (DOE) methodology as an auxiliary tool to evaluate the conditions of synthesis of the aluminum-rich zeolite Beta. Bimetallic catalysts with 50% platinum and 50% nickel ...
Catalisadores de CuO, Fe2O3 ou Co3O4 suportados em TiO2, CeO2 ou ZrO2: preparação via Sol-gel in situ ou impregnação e avaliação na redução de NO com CO
(Universidade Federal de São Carlos, 2012-04-13)
The minimization of the emissions of nitrogen oxides (NOx) is a subject of crucial interest, since them cause serious environmental problems which affect human health, vegetation and fauna. With the purpose to abate NOx, ...
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 ...
Imobilização de lipases pela técnica CLEA para síntese de biodiesel em reator de fluxo em vórtice
(Universidade Federal de São Carlos, 2017-10-30)
Due to the heterogeneity of the vegetable oils used in the synthesis of biodiesel, they can be transformed more quickly using a mixture consisting of lipases with different activities and specificities instead of single ...
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 ...
