Catalisadores de Mo suportados sobre sílica, sílica-titânia ou sílica-zircônia promovidos por Co ou Ni: avaliação do método de preparação e da composição do suporte na atividade para HDS
(Universidade Federal de São Carlos, 2012-04-30)
Hydrodesulfurization (HDS) catalysts containing Mo, NiMo or CoMo were supported on silica, silica-titania and silica-zirconia. These supports were synthesized by the sol-gel method, using citric acid as an agent to pore ...
Estudo experimental e numérico da fluidodinâmica e das transferências de calor e massa em um leito de jorro contínuo: uso da técnica CFD
(Universidade Federal de São Carlos, 2010-05-10)
In this work, the transport phenomena, which occur during the drying operation in a continuous spouted bed, are evaluated through experimental data and CFD simulations. Thus, this thesis was divided into three main parts: ...
Estudo da secagem de grãos em leito fixo, com e sem escoamento reverso do ar de secagem
(Universidade Federal de São Carlos, 2019-03-25)
Attempting to contribute to the development of the drying process in fixed bed, this work has the objective of the experimental study on the drying of barley grains in fixed bed, without and with drying airflow reversal. ...
Estratégias de melhoria do bioprocesso de produção de enzimas celulolíticas por Aspergillus niger a partir de bagaço de cana-de-açúcar para a produção de etanol de segunda geração
(Universidade Federal de São Carlos, 2015-03-05)
The second generation ethanol (2G) production from sugarcane bagasse is a promising
strategy to increase ethanol production per hectare. The 2G ethanol production comprises the steps of biomass pretreatment, hydrolysis ...
Expansão de células-tronco mesenquimais em biorreator single-use com movimento ondulatório visando aplicações terapêuticas
(Universidade Federal de São Carlos, 2019-04-30)
Mesenchymal Stem/Stromal Cells (MSCs) and MSC-derived Extracellular Vesicles (EVs) are being targeted in different medical areas. The MSCs are present in small proportions in tissues, thus making an in vitro expansion ...
Fermentação alcoólica extrativa com remoção de etanol por arraste com CO2 e recuperação por absorção
(Universidade Federal de São Carlos, 2019-02-28)
Ethanol removal by CO2 stripping during alcoholic fermentation is one way of overcoming the problem of inhibition by the ethanol. However, the lack of efficient methods to recover the removed ethanol still makes the use ...
Design and automation of a new reactor for enzymatic hydrolysis of lignocellulosic biomass at high solids loading
(Universidade Federal de São Carlos, 2019-05-10)
Several bottlenecks need to be overcome in order to establish the biorefinery concept as a feasible and lucrative second generation ethanol production technology. Lignocellulosic biomass enzymatic saccharification presents ...
Preparação e caracterização de sílicas híbridas com surfactantes catiônicos
(Universidade Federal de São Carlos, 2018-02-16)
The silica with structure MCM-41 has a hexagonal mesoporous arrangement with one dimensional pore system. This silica as synthesized contains cations (usually the CTA+) in your pores and catalytic sites with basic character ...
Produção de proteína recombinante a de superfície de pneumococo em escherichia coli: análise econômica e influência da plataforma de expressão
(Universidade Federal de São Carlos, 2019-07-24)
Streptococcus pneumoniae diseases represent a widespread public health. Pneumococcal surface protein A (PspA), which is recognized as one of the main virulence factors of this bacterium, has gained relevance in coverage ...
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 ...
