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 ...
Avaliação da produção de ciclodextrina glicosiltransferase (CGTase) por fermentação submersa de Paenibacillus sp.
(Universidade Federal de São Carlos, 2014-03-31)
Cyclodextrins (CDs) are cyclic oligosaccharides that show the ability to encapsulate a large number of organic molecules at the molecular level. Thus, they have large application in pharmaceutical, food, and cosmetics ...

(Universidade Federal de São Carlos, 2015-02-20)
In this work, different commercial carbon materials that could be used as electrodes for capacitive deionization were investigated: carbon cloth, carbon foam, carbon felt, carbon fiber, carbon veil and activated carbon ...
Caracterização e eficiência de diferentes meios filtrantes fibrosos na remoção de nanopartículas
(Universidade Federal de São Carlos, 2015-01-23)
Human exposure to nanoparticles is increasingly becoming a concern, including in the workplace, due to urban and industrial development and the increasing use of motor vehicles. Filtration using fibrous filters is among ...
Síntese e propriedades da zeólita faujasita nanométrica aplicada à catálise básica
(Universidade Federal de São Carlos, 2015-02-24)
In order to increase accessibility to catalytic sites, several studies currently aimed at reducing the diameter of the particles of zeolites to the nanometer scale. So, the increase in aging temperature caused a reduction ...
Estudo da absorção do vapor de etanol, carregado por gás carbônico, em diferentes solventes
(Universidade Federal de São Carlos, 2015-02-27)
In Brazil, ethanol is produced from fermentation route, being a process well consolidated and largely used for decades in the production units without facing significant changes in its design. In order to increase the ...
Avaliação do desempenho dos meios filtrantes de celulose RAD + e RAD Plus submetidos à filtração de gases a altas pressões
(Universidade Federal de São Carlos, 2015-01-23)
The gas filtration process has several advantages, such as to prevent damage to the environment and health of living beings and to avoid damage in the equipment used in various industrial processes. The filter media ...
Análise da secagem de partículas de alumina em secador vibrofluidizado
(Universidade Federal de São Carlos, 2015-03-04)
Activated alumina is widely used as a desiccant or as an adsorbent. In order to reuse the material, it is necessary to submit it to the drying process. In this context, a research was carried out to obtain the alumina with ...
Desenvolvimento de secador tipo cesto rotativo para a secagem de folhas de eucalipto (Corymbia citriodora)
(Universidade Federal de São Carlos, 2015-03-12)
The objective of this work is the development of a rotary type dryer for drying leaves. This dryer was built with the purpose of ensuring a proper mixing of the leaves during drying, to obtain a final product with homogeneous ...
