Avaliação do desempenho dos ciclos de filtração e regeneração dos meios filtrantes com limpeza por pulso de ar reverso
(Universidade Federal de São Carlos, 2013-04-11)
The presence of particles after the reverse air pulse cleaning process inside the filter medium ensures the increase in pressure drop of the subsequent cycle. The performance of the filter medium after several filtration ...
Estudos sobre a síntese da zeólita Beta na presença de íons fluoreto
(Universidade Federal de São Carlos, 2013-02-27)
One alternative to increase the octane rating of gasoline without the use of toxic or polluting compounds, banned by environmental legislation, is the transformation of linear paraffins of low octane number into branched ...
Estudo da cristalização da sacarose com adição de antissolvente
(Universidade Federal de São Carlos, 2013-03-28)
In the study of the sucrose crystallization process, the nucleation phenomena
and crystalline growth have been evaluated, when the systems were submitted to
different solvent and operational conditions.
The main objective ...
Craqueamento de cicloexano sobre zeólitas ácidas : atividade, seletividade e influência da presença de mesoporosidade
(Universidade Federal de São Carlos, 2012-03-30)
The need to develop a catalyst capable of processing heavy oil fractions, which is extracted from deeper wells, is essential. This concern has become more remarkable with the discovery of new oil fields in Brazil. This ...
Catalisadores à base de CuO, Fe2O3 ou CuO-Fe2O3 suportados sobre y-Al2O3, ZrO2 ou ZrO2/y-Al2O3 para a redução de NO com CO
(Universidade Federal de São Carlos, 2014-03-31)
NO, NO2 and N2O nitrogen oxides, named NOx, strongly contribute to the air pollution and to minimize their emissions are used catalytic processes. The catalytic reduction of NO with CO has the advantage to simultaneously ...
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 ...
Dessalinização usando tecnologia de deionização capacitiva
(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 ...
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 ...
