Catalisadores derivados de óxidos do tipo perovskita LaMO3, LaMFeO3 e LaMO3/γ-Al2O3 (M = Co, Ni ou Fe) aplicados à reforma a vapor de etanol
(Universidade Federal de São Carlos, 2014-07-30)
The hydrogen production has been extensively studied as a clean and powerful energy source, indicating that in the future hydrogen will became a key component for the global energy production, since burning fossil fuels, ...
“Compreensão das propriedades estruturais e de superfície de catalisadores de platina promovidos com cério através de técnicas de caracterização in situ sob a reação de deslocamento gás-água”
(Universidade Federal de São Carlos, 2014-04-28)
Pt based catalysts were measured with in situ X ray absorption fine structure spectroscopy (XAFS) to obtain information about the catalyst crystalline structure and electronic properties as a function of catalyst composition, ...
Recuperação de fosfolipídios residuais do farelo desengordurado de soja
(Universidade Federal de São Carlos, 2014-08-07)
In soybean processing industry, oil extraction with hexane generates defatted meal. Next, soybean protein concentrate (SPC) production from the defatted meal by using ethanol solution generates alcoholic micelle as a ...
Remoção de etanol por stripping empregando dióxido de carbono
(Universidade Federal de São Carlos, 2014-12-15)
In the ethanol fermentation processes, the product inhibition phenomenon limits the ethanol concentration in the fermented wine around 10% v.v-1, which results in a large volume of vinasse (around 12Lvinasse/Lethanol) and ...
Produção de hidrogênio e etanol através da fermentação acidogênica de águas residuárias agroindustriais em reator anaeróbio de leito fluidizado
(Universidade Federal de São Carlos, 2014-03-28)
The aim of this study was to evaluate the influence of hydraulic retention time (HRT), the origin of different inoculum (sludge from a UASB reactor for swine wastewater treatment and poultry slaughterhouse), and different ...
Contribuição ao estudo e modelagem matemática de reator anaeróbio de leito granular expandido (EGSB) tratando água residuária de suinocultura
(Universidade Federal de São Carlos, 2014-10-03)
Anaerobic systems have been widely studied and used in treatment of wastewater from agriculture and others. Among the existing technologies, there are the EGSB (Expanded Granular Sludge Bed) reactors, which have emerged ...
Avaliação do desempenho de meios filtrantes fibrosos na remoção de partículas nanométricas
(Universidade Federal de São Carlos, 2014-03-31)
Fibrous filters are highly efficient in removing micrometric particles, but when is related on the removal of particles in the nanometer range, their performance is still poorly understood. During filtration, as the particles ...
Síntese e avaliação catalítica das zeólitas com estrutura BEA, MFI e MTW na reação de Knoevenagel
(Universidade Federal de São Carlos, 2014-08-22)
The use of zeolites in basic catalysis is small, especially when compared to the numerous applications of material in their acid form. Inside this context, are even smaller the number of studies on the use of as-synthesized ...
Secagem de sólidos porosos granulares
(Universidade Federal de São Carlos, 2014-07-18)
In the present work, an experimental study about heat and mass transfer phenomena was carried out during drying of porous media when subjected to an upward flow of heated air. The cylindrical porous media consisted of ...
