Influência da composição da mistura reacional no desempenho de catalisadores NiFe/MgAl2O4 em reações de reforma
(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) ...
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 ...

"STUDIES ON COFFEE WASTEWATER TREATMENT USING COAGULATION AND ADVANCED OXIDATION PROCESSES" Brazil leads global coffee production, accounting for more than one-third of the global production and playing a crucial role 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 ...
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) ...
