Avaliação do precoating e dos meios filtrantes para filtro de mangas do processo de despoeiramento secundário da aciaria
(Universidade Federal de São Carlos, 2019-02-26)
Constant exposure to high concentrations of particulate matter present in the air has increased the number of cases of cardiorespiratory disease and death. Since then, has been a need for the development and improvement ...
Preparação e caracterização de sílicas híbridas com surfactantes catiônicos
(Universidade Federal de São Carlos, 2018-02-16)
The silica with structure MCM-41 has a hexagonal mesoporous arrangement with one dimensional pore system. This silica as synthesized contains cations (usually the CTA+) in your pores and catalytic sites with basic character ...
Proteína de soja como aditivo na sacarificação enzimática da biomassa vegetal: desenvolvimento e análise tecno-econômica do processo
(Universidade Federal de São Carlos, 2019-02-28)
The implementation of the biochemical conversion process of lignocellulosic biomass into biofuels and other bioproducts still have some technological challenges to be overcome, such as low yield of the enzymatic hydrolysis ...
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 ...
Niobium-based oxides for oxidative and reductive photocatalytic reactions
(Universidade Federal de São Carlos, 2020-02-21)
It is growing the number of studies related to alternative technologies allowing both, environmental remediation and clean energy production. In this sense, photocatalysis is a promising process, since it is sustainable ...
Monitoramento por espectroscopia dos compostos fenólicos e furaldeídos gerados no processamento de biomassa lignocelulósica
(Universidade Federal de São Carlos, 2017-02-20)
The major process challenge of the second-generation ethanol (2G) production is related
with characterization of hydrolyzate from lignocellulosic biomass, which often contains
high quantities of phenolic compounds and ...
Mitigação dos inibidores gerados no pré-tratamento da biomassa vegetal: impacto técnico-econômico-ambiental de diferentes rotas de processo na biorrefinaria
(Universidade Federal de São Carlos, 2021-04-27)
The presence of inhibitors is still an economic bottleneck that needs to be resolved in order to make 1G2G ethanol biorefineries feasible, requiring the development of technologies capable of improving their competitiveness ...
Estruturas de controle de biorreator baseadas em fluxos metabólicos para fermentações micro-aeradas
(Universidade Federal de São Carlos, 2021-04-15)
The supply of oxygen as a limiting nutrient in bioreactors is a challenge, as microorganisms may have different metabolic requirements, besides the difficulty of measuring this variable in low levels. Despite the obstacles, ...
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 ...
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, ...
