Síntese de catalisadores básicos na presença de surfactantes hexadeciltrimetilamônio
(Universidade Federal de São Carlos, 2023-06-12)
The synthesis of two basic catalysts — CTA-MCM-41 and ZIF-8 — were studied in the presence of the surfactant hexadecyltrimethylammonium bromide (CTAB), which forms micelles in aqueous dispersions. The catalysts were ...
Emprego de agente complexante e irradiações por feixe de elétrons e laser femtosegundos como estratégias para alterações da propriedade fotoluminescente do α-Ag2WO4
(Universidade Federal de São Carlos, 2023-06-22)
The discovery of room temperature photoluminescence has driven the development of various optical-electronic devices, motivated the search for new photoluminescent materials, and stimulated the modeling of this property ...
Precoating em filtro de mangas para remoção de material particulado e potencial redução da emissão de SO2 na dessulfurização
(Universidade Federal de São Carlos, 2023-05-25)
The steel industry is responsible for generating pollutants that need to be treated before being released into the atmosphere, various gases such as ammonia, benzene, carbon monoxide, sulfur dioxide and particulate matter. ...
Método para alocação de métricas de impacto ambiental em unidades industriais multiproduto
(Universidade Federal de São Carlos, 2023-05-24)
Life cycle assessment is an environmental, economic, and social evaluation technique focused on understanding and quantifying the impacts related to a particular product, good, or service. This assessment considers all ...
Hidrogenólise do glicerol a propilenoglicol sob catalisadores de Ni-Cu/Al2O3 utilizando hidrogênio produzido in situ
(Universidade Federal de São Carlos, 2023-03-27)
Catalytic hydrogenolysis of glycerol is one of the possible routes for converting glycerol into high commercial value products. The production of propylene glycol by catalytic hydrogenolysis of glycerol can be carried out ...
Análise da transferência de calor e parâmetros térmicos em leito empacotado de fermentação em estado sólido
(Universidade Federal de São Carlos, 2023-02-28)
Aiming at expanding the scale of solid-state fermentation processes (SSF), it is necessary to
develop and improve appropriate bioreactors. Of note are the packed-bed bioreactors (PBBs),
which have already been studied ...
Modelagem matemática de células a combustível alcalinas a glicerol direto
(Universidade Federal de São Carlos, 2023-02-27)
In the environmental and energy context, fuel cells are promising devices for the conversion of clean energy, with hydrogen being the most used fuel. However, its storage and distribution impose some difficulties, in ...
Propriedades catalíticas de aluminossilicatos funcionalizados com propilaminas
(Universidade Federal de São Carlos, 2023-03-17)
In this work, the functionalization with aminopropyl-trimethoxysilane (APTMS) of aluminosilicates precursors of the Na-LTA zeolite was explored in the synthesis of basic catalysts for the Knoevenagel condensation. The ...
Liquid-solid fluidized bed dynamics: experimental and computational analysis
(Universidade Federal de São Carlos, 2023-11-06)
The liquid-solid fluidization is a simple process intensification strategy. The method remains underexplored, in part, due to the lack of predictability. It is not trivial to assess its internal dynamics without a robust ...
