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 ...
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. ...
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, ...
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 ...
Produção de hidrogênio por reforma a vapor e oxidativa do etanol utilizando óxidos do tipo perovskita
(Universidade Federal de São Carlos, 2013-10-17)
This paper assesses the catalytic activities of LaCoO3 perovskite towards the steam reforming oxidative reaction of ethanol . Due to the low surface area which is commonly found on perovskite-type oxides , these were ...
Purificação da Cefamicina C por processo de adsorção em coluna de leito fixo
(Universidade Federal de São Carlos, 2013-04-29)
Cephalosporins are β-lactam antibiotics which are widely used in the treatment of bacterial infections. Within this group, cephamycin C (CefC) stands out from the others cephalosporins antibiotics due to its greater ...
