Influência dos íons metálicos na atividade e estabilidade de (hemi)celulases e no processo de sacarificação da biomassa
(Universidade Federal de São Carlos, 2015-02-26)
The enzymes involved in the conversion process of lignocellulosic biomass into second generation (2G) ethanol add a high cost to the process. Studies reported in the literature indicate that some metal ions, easily found ...
Interpoladores multilineares como metamodelos: integração à simulação de biorrefinarias no ambiente EMSO
(Universidade Federal de São Carlos, 2018-03-26)
The use of equation oriented simulators presents several advantages, mainly the separation between the mathematical model and the algorithm responsible for its resolution. This allows an easy implementation of new models ...
Catalisadores à base de Mo, CoMo e NiMo incorporados por impregnação ou in situ em γ-Al2O3, ZrO2 e γ-Al2O3-ZrO2 - avaliação na hidrodessulfurização do tiofeno
(Universidade Federal de São Carlos, 2011-03-28)
The preparation of Mo, CoMo or NiMo catalysts supported on -Al2O3, ZrO2 and - Al2O3-ZrO2 was studied. The zirconia contend added into alumina was 20 or 40 % wt.. The supports were synthesized via sol-gel ...
Preparação, caracterização e aplicação de eletrodos tridimensionais de carbono vítreo reticulado recobertos com filmes de PbO2 para a degradação do corante reativo AR 19 e glifosato
(Universidade Federal de São Carlos, 2016-05-06)
Electrodeposition of a PbO2 film was performed onto reticulated vitreous carbon (RVC)
substrates with porosities of 45, 60, and 80 ppi, at 65 ºC in a flow reactor, starting with a
solution containing Pb(NO3)2, surfactant, ...
Aproveitamento energético da vinhaça de cana-de-açúcar pela biodigestão em dois estágios em reatores anaeróbios de leito fluidizado: mesofílico e termofílico
(Universidade Federal de São Carlos, 2019-12-06)
This research evaluated the effect of operational parameters and of stage integration on the performance and energetic feasibility of the anaerobic digestion of sugarcane vinasse in anaerobic fluidized bed reactors. The ...
Modelagem cinética da síntese de galacto-oligossacarídeos usando a β-galactosidase de Kluyveromyces lactis
(Universidade Federal de São Carlos, 2020-12-22)
Galacto-oligosaccharides (GOS) have a high commercial value and are used in the food industry. GOS are non-digestible oligosaccharides (NDO), which are considered prebiotics. They can be produced enzymatically from substrates ...
Análise da viabilidade técnica e econômica da integração do processo de recuperação de etanol por arraste (stripping) com CO2 na indústria sucroenergética
(Universidade Federal de São Carlos, 2021-04-29)
Brazil is the world's largest sugarcane ethanol producer which puts the country in a stand-out position among the bioenergy producers. Ethanol is an important biofuel in the renewable energy matrix. In 2017, the Brazilian ...
Estudo da secagem da polpa do abacate (Persea americana)
(Universidade Federal de São Carlos, 2021-04-26)
The drying process can be carried out by different methods, but the choice directly influences the quality of the final product, which can obviously be affected by operational conditions. This work aims to study the drying ...
