Avaliação experimental de diferentes modos de operação de um biorreator de leito empacotado multicamadas para produção de celulases por cultivo em estado sólido
(Universidade Federal de São Carlos, 2021-02-26)
In the last years, the interest in solid state fermentation (SSF) for the most diverse applications have been increased due to the possibility of using agro-industrial residues and the low generation of wastewater. The ...
Fotoconversão de CO2 em produtos com valor agregado
(Universidade Federal de São Carlos, 2021-04-29)
In recent decades, due to population and industrial growth, the energy demand has increased significantly. However, much of the energy consumed comes from burning fossil fuels, which emit large amounts of gases that can ...
Conversão de furfural sobre zeólitas (Hf, Al)-ZSM-5 hierárquicas: controle da relação de sítios ácidos de Lewis e Brønsted e seu efeito na seletividade a produtos
(Universidade Federal de São Carlos, 2021-04-29)
One-pot catalytic processes using heterogeneous acid catalysts have been a promising strategy for the valorization of platform molecules from lignocellulosic biomass, such as the transformation of furfural (Fur) to ...
Modelagem matemática para sínteses enzimáticas de biossurfactantes catalisadas por lipases imobilizadas
(Universidade Federal de São Carlos, 2021-07-08)
Enzymatic reactions of esterification of fatty acids with carbohydrates generate biosurfactants, products with high capacity to reduce surface and interfacial tensions, applicable mainly in the food, pharmaceutical and ...
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 ...
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 ...
Aproveitamento de CO2 para a produção de metanol e compostos C2+ aplicando catalisadores à base de Cu e Fe
(Universidade Federal de São Carlos, 2021-08-10)
Considering the approaches to use of the CO2, this work aimed to study CO2 hydrogenation at gas phase and CO2 reduction (CO2RR) via electrocatalysis. Through these methodologies a wide variety of value-added products can ...
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, ...
Monitoramento da hidrólise enzimática de bagaço de cana-de-açúcar por métodos espectrofotométricos
(Universidade Federal de São Carlos, 2020-02-23)
The production process of 2nd generation ethanol (2G), using sugarcane bagasse, is a promising way to increase ethanol production without increasing the cultivation area. However, the process has been studied to become ...
