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 ...
Captura de CO2 de gases de combustão utilizando óxido de cálcio
(Universidade Federal de São Carlos, 2018-02-23)
Calcium oxide (CaO) based materials were prepared, characterized and subjected to cyclic carbonation and decomposition reactions in order to evaluate the carbon dioxide capture capacity (CO2) and the stability of the ...
Avaliação experimental de um ciclone adaptado com bocais pulverizadores de água
(Universidade Federal de São Carlos, 2018-02-19)
Brazil is a world leader in the production of sugar and ethanol by using sugar cane. Nonetheless, in order to supply the energy demands of this sector, the sugarcane bagasse is used as a fuel in boilers and its burning ...
Modelagem fenomenológica da síntese enzimática de biodiesel etanólico utilizando lipase solúvel
(Universidade Federal de São Carlos, 2018-03-27)
The kinetics study of the synthesis of ethyl biodiesel allows a deeper understanding of the enzymatic process, providing an important tool for process design, optimization and control. Most of the models proposed in the ...
Análise e modelagem da síntese enzimática de galacto-oligossacarídeos
(Universidade Federal de São Carlos, 2016-03-31)
Galactooligosaccharides are indigestible oligosaccharides with recognized prebiotic capacity. They can be synthesized enzymatically from lactose-rich substrates using the β-galactosidase enzyme by means of a kinetically ...
Inovações na produção de hidrolisados de soja: modelagem e análise econômica de processo
(Universidade Federal de São Carlos, 2012-04-25)
Soybean and its derivatives have the desired properties for food either for humans or various animals because of its high protein content, which is associated to a good balance of amino acids. However, when the protein is ...
Desenvolvimento de sistema nebuloso (fuzzy) para controle do oxigênio dissolvido no cultivo de escherichia coli para expressão de proteínas recombinantes
(Universidade Federal de São Carlos, 2018-02-26)
One very important bioprocess is the cultivation of recombinant E. coli for expression of heterologous proteins. For this, High Cell Density Culture is one of the most widely used technique. Although it results in cell ...
Controle nebuloso ("fuzzy”) aplicado à combustão em caldeiras a bagaço de cana
(Universidade Federal de São Carlos, 2018-04-26)
In the sugarcane industry, boilers are widely used for cogeneration. This term designates the simultaneous generation of more than one type of energy, namely thermal and electrical, from the same fuel source. This industry ...
Parâmetros cinéticos da cristalização de sacarose em diferentes escalas
(Universidade Federal de São Carlos, 2018-03-07)
This work aims to determine kinetic parameters capable of describing the crystallization of sucrose using bench scale and pilot scale reactors. Sucrose was chosen because it is a very important product for Brazil, which ...
Modelagem e simulação de células a combustível de etanol direto
(Universidade Federal de São Carlos, 2016-03-04)
Two mathematical models of a Direct Ethanol Fuel Cell (DEFC) considering both an
ideal (complete ethanol oxidation) and a realistic behavior (partial oxidation with by-products) were implemented in 3D geometries, adapted ...
