Catalisadores Ni/SBA-15 com adição dos promotores aplicados a tri reforma do metano
(Universidade Federal de São Carlos, 2021-10-27)
Tri-reforming of methane (TRM) is a combination of steam and dry reforming and partial oxidation of methane reactions in the same reactor. Since it occurs at high temperatures and has water vapor in the reactor feed, TRM ...
Controle policromático de luz aplicado à produção de microalgas
(Universidade Federal de São Carlos, 2021-12-08)
Microalgae have drawn the attention of the biotechnology industry for being natural synthesizers of high added value products such as β-carotene, astaxanthin, lutein, docosahexaenoic acid, proteins, and pigments. However, ...
Análise técnico-econômica-ambiental da produção de nanocelulose em biorrefinarias de cana-de-açúcar
(Universidade Federal de São Carlos, 2021-08-31)
The production of ethanol, sugar and energy in Brazilian sugarcane biorefineries
generates a large number of residues, such as bagasse and straw. An alternative is the
reuse of these residues as feedstock for obtaining ...
Cellulose nanomaterials isolated via enzymatic and mechanical routes for application in hydrogels
(Universidade Federal de São Carlos, 2021-11-10)
The integrated production of different bioproducts has been considered essential to make biorefineries economically viable. Among the bioproducts, cellulose nanomaterials (CNs) have attracted significant attention due to ...
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 ...
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 ...
Produção de ácido hialurônico microbiano: viabilidade econômica e avaliação de impactos ambientais
(Universidade Federal de São Carlos, 2022-10-28)
Hyaluronic acid is a biopolymer with unique structural and rheological properties, that, initially, was produced by extraction from animal tissue, from rooster comb. However, it used non-ecofriendly solvents (chloroform) ...
Catalisadores NiFe/MgAl2O4 em reações de reforma a vapor: propriedades estruturais e catalíticas em função da composição Ni:Fe e temperatura de reação
(Universidade Federal de São Carlos, 2021-12-20)
This thesis evaluated the application of Ni-, Fe- and Ni-Fe/MgAl2O4 catalysts in Ethanol Steam Reforming (ESR), Ethanol Steam Reforming with hydrogen gas (ESRH), Methane Dry Reforming (RSM), Methane Steam Reforming (RVM) ...
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 ...
