Estudo da secagem de grãos em leito fixo, com e sem escoamento reverso do ar de secagem
(Universidade Federal de São Carlos, 2019-03-25)
Attempting to contribute to the development of the drying process in fixed bed, this work has the objective of the experimental study on the drying of barley grains in fixed bed, without and with drying airflow reversal. ...
Fermentação alcoólica extrativa com remoção de etanol por arraste com CO2 e recuperação por absorção
(Universidade Federal de São Carlos, 2019-02-28)
Ethanol removal by CO2 stripping during alcoholic fermentation is one way of overcoming the problem of inhibition by the ethanol. However, the lack of efficient methods to recover the removed ethanol still makes the use ...
Evaluation of filter media with fiber layer produced by the centrifugal spinning method with biocidal effect
(Universidade Federal de São Carlos, 2020-03-12)
This study aimed to evaluate the air filtration performance of the fiber layer, produced by centrifugal spinning equipment, adhered to the surface of a commercial filter media applied to the internal ventilation system. ...
Contribuição ao estudo do desempenho de biorreatores airlift de circulação interna: análise das condições operacionais e da geometria do equipamento
(Universidade Federal de São Carlos, 2018-04-26)
The high oxygen transfer capacity associated with low energy consumption have made the airlift bioreactor an important equipment to be used in bioprocesses, with the performance of these devices being strongly dependent ...
Estudo sobre o desempenho de válvulas não-mecânicas como alimentadores de biomassa residual de borra de café em reatores de leito pneumático circulante: experimentação e modelagem via CFD-TFM
(Universidade Federal de São Carlos, 2020-08-24)
The continuous and stable feeding of particulate solids to reactors is essential for energy cogeneration in industrial processes, for example, by using biomass residues. Nevertheless, flow instabilities and blockage of ...
Análise técnico-econômica-ambiental da produção de nanocelulose em biorrefinarias de cana-de-açúcar
(Universidade Federal de São Carlos, 2021-08-31)
The production of ethanol, sugar and energy in Brazilian sugarcane biorefineries
generates a large number of residues, such as bagasse and straw. An alternative is the
reuse of these residues as feedstock for obtaining ...
Análise de diferentes configurações do leito de jorro com agitador mecânico e do equipamento convencional
(Universidade Federal de São Carlos, 2022-03-24)
The mechanical spouted bed emerged as a modification of the conventional spouted bed
to minimize problems in the movement of solids and the need for high air flows just for
the existence of the spouting regimen. Therefore, ...
Produção de esferoides de células tumorais de câncer de bexiga num biorreator de vórtice de Taylor
(Universidade Federal de São Carlos, 2018-03-08)
Two-dimensional (2D) cell culture has been the common platform for evaluating anticancer drugs. However, three-dimensional (3D) cell cultures, such as multicellular tumor spheroids (MCTS), best resemble tumor in vivo ...
Controle policromático de luz aplicado à produção de microalgas
(Universidade Federal de São Carlos, 2021-12-08)
Microalgae have drawn the attention of the biotechnology industry for being natural synthesizers of high added value products such as β-carotene, astaxanthin, lutein, docosahexaenoic acid, proteins, and pigments. However, ...
Intermittent drying and draft tube design for spouted bed
(Universidade Federal de São Carlos, 2021-12-08)
The conventional spouted bed has presented several limitations that restrict the use on an industrial scale. Thus, studies of different methodologies and configurations have been performed to overcome such limitations. ...
