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 ...
Avaliação por CFD da fluidodinâmica e da transferência de calor em leitos de jorro para diferentes ângulos da base cônica
(Universidade Federal de São Carlos, 2019-02-27)
The spouted bed is an equipment that provides fluid-particle contact due to the cyclic movement of solids in its interior, which results in high rates of heat and mass transfer between phases. The spouted bed is used in ...
Avaliação da produção de açúcar utilizando reconciliação de dados, estatística multivariada e modelagem fenomenológica da cristalização
(Universidade Federal de São Carlos, 2019-02-25)
Sugarcane, grown in more than a hundred countries, is one of the major crops of the world. Brazil is the world’s largest producer. Sugarcane industries are constantly seeking to reduce the industrial process losses, to ...
Análise do escoamento em um ciclone adaptado com bicos aspersores de água utilizando fluidodinâmica computacional (CFD)
(Universidade Federal de São Carlos, 2019-02-25)
Cyclonic separators are widely used in industries for gas-solid separation process. Its low cost in building, operating and maintenance, as well as the ability to operate at high temperatures and pressures, makes it a good ...
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 ...
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 ...
Avaliação do precoating e dos meios filtrantes para filtro de mangas do processo de despoeiramento secundário da aciaria
(Universidade Federal de São Carlos, 2019-02-26)
Constant exposure to high concentrations of particulate matter present in the air has increased the number of cases of cardiorespiratory disease and death. Since then, has been a need for the development and improvement ...
Avaliação do comportamento fluidodinâmico lı́quido-sólido em biorreatores de leito fluidizado utilizando técnicas de fluidodinâmica computacional (CFD)
(Universidade Federal de São Carlos, 2018-09-20)
Anthropogenic actions have promoted technological challenges, for example, in the treatment of large quantities of wastewater, which can be done in fluidized bed bioreactors. For the study of these bioreactors, numerical ...
Contribuições ao estudo da secagem da borra de café em leito vibrofuidizado
(Universidade Federal de São Carlos, 2019-03-15)
Brazil is the largest producer of coffee in the world, half of this production is destined to the soluble coffee industry, that generates a amount of waste. The spent coffee grounds leave the fabrication processo f the ...
Determinação experimental de parâmetros de interação e aplicação na simulação CFD-DEM de leito de jorro
(Universidade Federal de São Carlos, 2020-02-19)
Spouted beds feature the intense mixture of solids, which favors the mechanisms of heat and mass transfer. The understanding of these phenomena is associated with the difficult to obtain details of fluid dynamics by the ...
