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 ...
Hidrogenação de CO2 sobre catalisadores à base de elementos não-nobres: a influência da composição química do catalisador e de condições reacionais na produção de álcoois
(Universidade Federal de São Carlos, 2022-11-30)
Strategies to reduce CO2 emissions and control the increase in atmospheric levels of this gas are urgent. A promising approach to help minimize the accumulation of CO2 in the atmosphere and the corresponding negative ...
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 ...
Desenvolvimento de catalisador heterogêneo para síntese de biodiesel em sistema contínuo
(Universidade Federal de São Carlos, 2023-03-15)
The growing interest in biodiesel production has encouraged studies that enable the generation of national technology in this field, considering that, industrially, biodiesel is already produced in continuous systems, but ...

(Universidade Federal de São Carlos, 2023-12-01)
Climate change is a current topic of much debate around the world and is a consequence of the impact of the intensification of the greenhouse effect caused by the accumulation in the atmosphere of gases such as carbon ...
Previsão da composição e dos volumes das fases durante a cinética enzimática do biodiesel etílico com lipase líquida utilizando modelo UNIFAC
(Universidade Federal de São Carlos, 2023-06-29)
The production of biodiesel catalyzed by lipases, especially by transesterification of vegetable oils, has been gaining importance in recent decades because it is an efficient and sustainable process. The main differential ...
Desenvolvimento e estudo da influência de um modelo de força de lubrificação em um leito fluidizado líquido utilizando CFD-DEM não resolvido
(Universidade Federal de São Carlos, 2023-02-28)
Solid-fluid multiphase flows are common occurrences in chemical engineering applications. Due to the scale and unpredictability of the fundamental phenomena in these systems, microscopic interactions between individual ...
Modelagem matemática aplicada ao estudo de células a combustível a etanol direto
(Universidade Federal de São Carlos, 2022-03-09)
The current fuel cell market is dominated by Hydrogen cells. Nevertheless, due to Hydrogen’s high reactivity, the difficulty in storage and the lack of infrastructure to distribute it, Hydrogen cells might not be the most ...
