Pré-tratamento do bagaço de cana de açúcar com amônia aquosa para a produção de etanol
(Universidade Federal de São Carlos, 2011-02-28)
The aim of this work was evaluated the sugarcane bagasse (SCB) pretreatment by aqueous ammonia, an alkaline method. Samples of SCB (in natura and steam exploded unwashed) were pretreated with ammonium hydroxide solution ...
Desenvolvimento de ambiente integrado para simulação e otimização estática da produção de etanol a partir de bagaço de cana-de-açúcar por rota bioquímica
(Universidade Federal de São Carlos, 2012-02-23)
Sugarcane bagasse is an interesting option for second generation ethanol production. However, its use for this purpose is constrained by the energetic self-suficiency of the industrial plant, apart from the necessary ...
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 ...

(Universidade Federal de São Carlos, 2010-03-26)
Currently, scientific research in the field of nanotechnology has attracted growing interest because of its several applications, either through design of new products, materials characterization, production and application ...
Fração de filme em lavadores Venturi
(Universidade Federal de São Carlos, 2010-07-30)
Venturi scrubber is an equipment applied to particulate material removal, soluble gases absorption, and gas stream odors reduction. This device utilizes of a liquid wash that collides a high velocity gas inside the scrubber. ...
Análise da dinâmica de secagem de pasta em leito de jorro
(Universidade Federal de São Carlos, 2016-02-22)
Although there are several mathematical models in the literature used for paste drying in spouted beds, few of them have focused on transient analysis of dynamic system. Therefore, the purpose of this study was to integrate ...
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 ...
Produção de ácido clavulânico por Streptomyces clavuligerus em cultivos em batelada e batelada alimentada com pulsos de glicerol sob diferentes condições de temperatura
(Universidade Federal de São Carlos, 2010-03-25)
The production of enzymes β-lactamases by pathogenic bacteria is the most common mechanism of resistance to β-lactam antibiotics. The β-lactamases catalyze the hydrolysis of β-lactam ring, splitting the ...
