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 ...
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 ...
Transferência de oxigênio e condições de cisalhamento em biorreator convencional com impelidores orelha de elefante
(Universidade Federal de São Carlos, 2013-09-30)
Due to owing to the nature of culture involving aerobic filamentous microorganisms, conventional aerated stirred-tank bioreactors using the Rushton turbine impeller are widely employed in order to achieve good mixing and ...
Desenvolvimento de um programa computacional em Scilab® baseado no método Pinch de integração energética
(Universidade Federal de São Carlos, 2013-02-25)
The increasing concern about environmental impacts caused by human activities has led scientists to look for ways to settle the situation. As regards chemical industries, one of the main focuses of this concern is the ...
Modelagem da eficiência de coleta em ciclones utilizando a fluidodinâmica computacional
(Universidade Federal de São Carlos, 2013-09-30)
Cyclones are used to separate suspended particles from gas streams. The analysis of flow inside the cyclone is complex due to the large number of parameters and operating variables that influence the dynamics of the system. ...
Estudo das propriedades estruturais dos catalisadores de Cu e Cu-Ce suportados em alumina aplicados à reação de deslocamento gás-água
(Universidade Federal de São Carlos, 2013-03-12)
Particle size effect and Ce addition on the catalytic properties of Cu/Al2O3catalysts were investigated for the water gas shift reaction (WGS). The catalysts were prepared by dry impregnation of an aqueous solution of ...
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 ...
Zéolitas ZSM-12 mesoporosas textura, cristalinidade e atividade ácida para o craqueamento de cicloexano
(Universidade Federal de São Carlos, 2013-09-12)
The research addressed the generation of mesoporosity in the zeolite ZSM-12 (MTW). In the first part we studied the synthesis of ZSM-12 via conventional methodology and in the presence of a mesopore directing agent, ...
Produção de etanol anidro por destilação extrativa utilizando soluções salinas e glicerol
(Universidade Federal de São Carlos, 2013-02-15)
An alternative of renewable fuel is the anhydrous ethanol from biomass. Its production has to aim the minimum consumption of hydric and energetic resources. The bottleneck of the process is located in the downstream that ...
Catalisadores de Cu/CeO2 modificados com La aplicados à reação de deslocamento gás-água
(Universidade Federal de São Carlos, 2013-03-14)
The water gas shift reaction (WGSR) is often used in industrial processes in order to increase hydrogen production, as well as to remove quantities of CO in the chains produced by steam reforming of hydrocarbons. In this ...
