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 ...
On the drag coefficient in particle agglomerates: a CFD approach to propose a new drag correlation
(Universidade Federal de São Carlos, 2023-07-31)
In particle-laden flows, it is essential to model the fluid-particle interaction. However, depending on effects such as friction and attraction, surface properties, and collisions, particles can agglomerate, generating new ...
Secagem convectiva de concentrado de minério de ferro: abordagem experimental e simulações por fluidodinâmica computacional
(Universidade Federal de São Carlos, 2023-02-27)
Conventional transfer chutes are equipment used to change the solids flow direction in transporting systems that use conveyor belts. During operation, the solid transported by the upper conveyor belt enters the chute and ...
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 ...
Aplicação de redes neurais artificiais no sinal FBRM para monitorar a cristalização de Paracetamol
(Universidade Federal de São Carlos, 2022-02-23)
Obtaining high added value products in the chemical industry is directly related to separation operations carried out to achieve the specifications required by regulatory agencies. The crystallization, one of the most used ...
Transesterificação heterogênea catalisada por sílicas contendo sítios básicos e cátions cetilvinilimidazólio
(Universidade Federal de São Carlos, 2022-05-12)
Homogeneous catalysis is the most used process in the production of biodiesel, although this process has several disadvantages such as: the catalyst cannot be easily reused and requires parallel processes for separation ...
Biofertilizantes como reatores em grânulo: sistemas carreadores com Aspergillus niger e Trichoderma asperelloides para ações no controle biológico, promoção do crescimento de plantas e solubilização de fósforo
(Universidade Federal de São Carlos, 2021-10-14)
In recent years, the importance of microorganisms role in maintaining agricultural productivity has been highlighted, being essential in cycling nutrients and production of metabolites to contribute to plant growth and ...
Estudo do processo integrado de fermentação alcoólica extrativa com CO2 com desidratação por adsorção e recuperação por absorção
(Universidade Federal de São Carlos, 2022-06-30)
To minimize the effects of ethanol inhibition, increase productivity, and reduce energy and environmental footprint, different strategies of ethanol removal by gas stripping with CO2 during alcoholic fermentation have been ...
Design of new immobilized lipases for biotransformations in aqueous and organic media
(Universidade Federal de São Carlos, 2023-01-30)
A review of the literature covering research on the immobilization of lipases on hydrophobic supports was performed using systematic mapping (MS) concepts. The MS approach enabled the identification of gaps that led to the ...
Otimização da produção de ácido 3-hidroxipropiônico por Escherichia coli via engenharia metabólica e de processos
(Universidade Federal de São Carlos, 2022-10-14)
The integration of substrates from bioprocesses is of great interest due to the need of destination
for them and the possibility of converting them into value-added products. Among these
substrates, the hydrolysates ...
