Estudos sobre a acessibilidade aos sítios de zeólitas para aplicação em catálise básica
(Universidade Federal de São Carlos, 2022-03-28)
The application of zeolites in catalysis is restricted when bulkier molecules are involved, for example, in the manufacture of fine chemicals, where the reactant molecules are unable to access their micropores. A solution ...
Estudo da transferência de calor e de massa em um leito fixo espesso de grãos de sorgo com reversão de sentido do escoamento de ar
(Universidade Federal de São Carlos, 2022-03-31)
Drying is one of the highest cost unit operations in the chemical industry, with complex momentum, heat and mass transfer mechanisms. The main objective of this work was to develop a systematic study on thick layer drying, ...
Avaliação de meios filtrantes com diferentes técnicas de fabricação em filtros de mangas
(Universidade Federal de São Carlos, 2022-04-26)
Air pollution by particulate matter has been the subject of study by many researchers,
where they report that these particles can penetrate through the bloodstream causing
serious health problems. To reduce the negative ...
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, ...
Avaliação técnico-econômica da produção de metanol a baixas temperaturas pela oxidação parcial do metano
(Universidade Federal de São Carlos, 2022-02-25)
Large volumes of natural gas (NG) are released or flared on oil platforms, emitting mainly methane, carbon monoxide, and carbon dioxide. These greenhouse gases (GHG) represent an environmental and health hazard. In this ...
Desenvolvimento de um secador de bandejas para a secagem de folhas medicinais e análise da secagem de ramos de barbatimão (Stryphnodendron adstringens)
(Universidade Federal de São Carlos, 2022-03-28)
Barbatimão bark (Sryphnodendron adstringens) has been used in folk medicine for years to treat many diseases. Recently, studies indicated the potential of barbatimão leaf extract as a chemopreventive agent and as a promising ...
Avaliação da viabilidade do uso de redes neurais artificiais para o desenvolvimento de um softsensor de biomassa de microalgas em fotobiorreator
(Universidade Federal de São Carlos, 2022-02-21)
Microalgae are natural sources of biomass, unsaturated fatty acids, carotenoids, xanthophylls, vitamins, proteins, minerals and enzymes; compounds of great commercial importance. Furthermore, since biofuels have become a ...
Modelagem matemática e simulação computacional aplicadas ao estudo de processos de co-digestão anaeróbia de glicerol e/ou melaço
(Universidade Federal de São Carlos, 2022-11-29)
Policies worldwide are increasingly incentivizing and pressuring countries to use renewable sources of energy. Brazil was a pioneer in the production of bioethanol and is one of the main producers of biodiesel. Due to the ...
Determinação experimental de Coeficientes de Atrito de diferentes partículas para aplicação na modelagem de escoamentos densos
(Universidade Federal de São Carlos, 2022-08-31)
Systems involving particles are very common in many engineering applications. The interaction between these particles and of them with the equipment surfaces can strongly affect their dis-tribution, which will often influence ...
Implementação de sistema nebuloso (“fuzzy”) para controle de oxigênio dissolvido no cultivo de Escherichia coli para expressão de proteínas recombinantes
(Universidade Federal de São Carlos, 2022-04-27)
Due to low oxygen solubility in water and mechanical limitations of a bioreactor, ensuring an adequate dissolved oxygen supply during a recombinant Escherichia coli cultivation is a major challenge in process control. In ...
