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 ...
Estudo do desempenho de eliminadores de névoa na fermentação alcoólica extrativa
(Universidade Federal de São Carlos, 2021-08-27)
The ethanol removal by gas stripping with CO2 offers a potential way to minimize the inhibitory effects of ethanol on yeast cells during the alcoholic fermentation, allowing higher ethanol volumetric productivity compared ...
Estudo da reação de hidrogenação de CO2 em materiais à base de Cu via catálise heterogênea
(Universidade Federal de São Carlos, 2022-07-07)
CO2 is a greenhouse gas whose production has intensified in recent decades, generating its accumulation in the Earth’s atmosphere. Thereby, numerous negative environmental changes, such as the aggravation of the greenhouse ...
Catalisadores NiMo/γ-Al2O3 aditivados com Nb - Atividade para a hidrodessulfurização de tiofeno
(Universidade Federal de São Carlos, 2021-04-30)
The burning of fuels in the industry or in vehicle engines is a direct agent in the generation of the atmospheric pollution through the emission of contaminating gases such as NOx and SOx. To minimize this impact, environmental ...
Efeito de forças hidrodinâmicas em colisões partícula-superfície em diferentes meios fluidos
(Universidade Federal de São Carlos, 2023-12-20)
Energy dissipation in systems, such as solid-gas and solid-liquid, can occur in several ways, including resistance to motion, interfacial interactions, deformation, and particle collision. In gas-solid flows, the main ...
High-performance chloride-doped polyaniline activated carbon modified with PluronicTM template for electrochemical desalination
(Universidade Federal de São Carlos, 2023-02-15)
Activated carbon obtained from chloride-doped polyaniline (PAC/Cl) is an attractive material for brackish water desalination using capacitive deionization (CDI), due to its easy synthesis, low cost, and fast electrosorption ...
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 ...
Electrochemical desalination using polyglycerol activated carbon: electrode, cell, and process development
(Universidade Federal de São Carlos, 2022-11-18)
Capacitive deionization (CDI) has emerged as a promising electrochemical technology for the desalination of brackish water, which promotes the electrosorption of ions in the electrical double layer. In recent years, there ...
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 ...
Estudos sobre a produção de nanofibras de PVA via electrospinning e sua aplicação em filtração de nanoaerossóis
(Universidade Federal de São Carlos, 2022-09-30)
Poly(vinyl alcohol) nanofibers for air filtration were produced by electrospinning using citric acid and different concentrations of Triton X-100 surfactant. Filtration tests with nanoparticles (5.94–224.7 nm) and tests ...
