Avaliação da transferência de quantidade de movimento, energia e das espécies químicas em um prato perfurado de destilação através da fluidodinâmica computacional
(Universidade Federal de São Carlos, 2016-03-24)
The development of the design of chemical processes has received increasing improvement, incorporating sophisticated mathematical models, which allowed better simulation of its real behavior. Distillation is one of the ...
Lipases imobilizadas em suportes híbridos como biocatalisadores para a produção de ésteres de açúcares
(Universidade Federal de São Carlos, 2016-05-25)
The use of lipases in large scale processes is limited due to their high cost. The reuse of the catalyst can contribute to make the enzymatic process more attractive. Hydrophobic supports are the mostly used for lipase ...
Destilação instantânea em regime transiente: Dorna Volante modificada
(Universidade Federal de São Carlos, 2016-03-29)
In the intense search for better environmental conditions, it is necessary not only to invest in renewable fuels but also to seek improvements in the production processes of these fuels. With this in mind, in this work the ...

(Universidade Federal de São Carlos, 2016-05-02)
It is necessary knowing the characteristics of the filter media and how they influence the
filtration process to improve the filter media. With this, the aim of this study was to
characterize the filter media containing ...
Lipase “whole-cell” de Streptomyces clavuligerus : produção, caracterização e aplicação em meio orgânico
(Universidade Federal de São Carlos, 2016-08-25)
Cell-associated lipases have been considered biocatalysts economically advantageous because
they are produced at low cost, avoiding further recovery or purification steps. Few studies
regarding Streptomyces clavuligerus ...
Estudo do pré-tratamento hidrotérmico e hidrólise enzimática da palha de cana-de-açúcar
(Universidade Federal de São Carlos, 2016-04-08)
The complex cell wall structure of lignocellulosic biomass makes pretreatment one of the most
relevant 2G ethanol production process steps due to the difficulty of hydrolyzing lignocellulose
to fermentable sugars and the ...
Oxidação de CO sobre catalisadores de Co e/ou Mn modificados com Mo e suportados em SBA-15 – Efeito do método de preparação e da presença de vapor de água e dióxido de enxofre na atividade catalítica
(Universidade Federal de São Carlos, 2016-08-25)
The increasing demand for oil and oil derived products contributed to the alarming increase in the gaseous pollutants emissions in general and mainly contributed to the increase in carbon monoxide (CO) emissions in the ...

(Universidade Federal de São Carlos, 2016-04-29)
The effect of metal composition (Ni,Co) and the reactants composition (H2:H2O:Butanol) in the catalytic properties were studied for the Ni,Co/MgAl2O4 catalysts in the reaction of steam reforming of butanol (SRB) The catalysts ...
Estudo de um leito fixo de pequena espessura utilizando CFD
(Universidade Federal de São Carlos, 2016-03-07)
Studies carried out in fixed bed, a major experimental research equipment, use a simplified approach for assessing, for example, drying kinetics of various materials, known as thin-layer approach. For a given system can ...
Otimização descentralizada coordenada aliada a estratégias de controle plantwide para o controle de processos químicos
(Universidade Federal de São Carlos, 2016-07-08)
Chemical plants are increasingly complex and integrated with recycle streams promoting
energy integration and increasing process yield. This results in a complex dynamic
behavior which can interfer in control systems ...
