Modelagem e simulação dinâmica de reatores de leito fixo
(Universidade Federal de São Carlos, 2011-02-25)
This work investigated numerical methods in the solution of mathematical models of fixed-bed reactors. For the reactors modeling and simulation, two numerical methods were used: sequencing method (SM) and finite volume ...
Estudos preliminares de produção de ácido glucônico a partir de sacarose invertida em biorreator airlift
(Universidade Federal de São Carlos, 2011-12-22)
The use of sucrose for the production of industrial inputs with higher added value has a great industrial interest, especially glucose and fructose which present many advantages over sucrose in industrial processes. Gluconic ...
Preparação de derivados de β-glicosidase por imobilização em suportes sólidos derivatizados
(Universidade Federal de São Carlos, 2011-02-25)
B-glucosidase (BG) is an important enzyme for several biotechnological applications. This enzyme plays an important role in hydrolyses of lignocellulosic biomass in order to produce second generation ethanol (2G ethanol). ...
Estudo da cinética e do equilíbrio da adsorção da cefamicina C em resina de troca iônica e simulação do processo contínuo
(Universidade Federal de São Carlos, 2011-03-01)
The cephamycin C (CefC) is a beta-lactam antibiotic produced from submerged and aerated cultures of Streptomyces clavuligerus. Acts as inhibitor of cell wall formation of Gram-negative bacteria and is resistant to the ...
Isomerização do n-Hexano por platina suportada na zeólita H-ZSM-5 : efeito do teor de alumínio
(Universidade Federal de São Carlos, 2011-08-01)
The objective of this study was to verify the influence of the Si/Al ratio (11.5, 15.0, 25.0, 40.0 and 140.0) in zeolite ZSM-5 in the conversion, activity, selectivity and stability as bifunctional catalysts (Pt/H-ZSM-5) ...
Catalisadores à base de ferro, vanádio e molibdênio suportados em titanatos lamelares e TiO2 comercial na aplicação da reação de NO com NH3
(Universidade Federal de São Carlos, 2011-10-27)
The minimization of emissions of nitrogen oxides (NOx) is a subject of great interest because they cause serious environmental problems affecting human health, flora and fauna. To break down the NOx catalytic reduction of ...
Produção de monoéster via etanólise por hidrotalcitas termoativadas: síntese e caracterização
(Universidade Federal de São Carlos, 2011-03-31)
Among biofuels of the 1st generation, biodiesel stands out for its equivalent features to those of mineral diesel, however less polluting. It can be obtained by transesterification of triglyceride fats or vegetable oils ...
Estudo cinético da hidrólise enzimática de celulose de bagaço de cana-de-açúcar
(Universidade Federal de São Carlos, 2011-03-28)
This work presents a kinetic study of the enzymatic hydrolysis of three cellulosic substrates: filter paper (FP), used as a de-lignified substrate model; sugarcane bagasse (SB) steam exploded; and acid treated SB, the last ...
Desenvolvimento de processo não-convencional para produção de celulases por Aspergillus niger em biorreator pneumático na presença de bagaço de cana-de-açúcar
(Universidade Federal de São Carlos, 2011-07-29)
In Brazil, sugarcane bagasse stands out as an abundant and available source of lignocellulosic material in sugar mills. It has structural features that make it a possible inducer for cellulase production by microorganisms. ...
Melhoria do cetano em óleo diesel : abertura do ciclo da decalina sobre catalisadores de Pt, Ir ou Rh suportados em zeólitas FAU e BEA
(Universidade Federal de São Carlos, 2011-06-08)
Environmental laws and stricter quality specifications have driven the development of technologies for improving the cetane number in diesel fuel. In addition to the saturation of (poly)aromatic compounds, responsible for ...
