There are many industries which use powders somewhere in their production process, such as: food, pharmaceuticals, ceramics, cement and fertilizer industries. The knowledge of properties associated with the flowability of ...
Síntese de nanopartículas de ouro por precipitação
(Universidade Federal de São Carlos, 2012-04-26)
Gold nanoparticles have properties with great interest in applications in biomedicine, catalysis, optics and electronics. This study seeks to produce stable, size-homogeneous and well-dispersed particles. The chosen method ...
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 ...
Nonlinear constrained optimization with flexible tolerance method: improvement and application in systems synthesis of mass integration
(Universidade Federal de São Carlos, 2015-03-13)
Este trabalho visa a otimização não-linear restrita usando o Método das Tolerâncias Flexíveis (FTM) e na aplicação do mesmo na síntese de sistemas de integração mássica. A integração mássica é uma técnica que permite 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 ...
