Cristalização da sacarose : estudos experimentais, modelagem matemática e influência de impurezas
(Universidade Federal de São Carlos, 2016-02-29)
Sugarcane is one of the main Brazilian crops. Studies encompassing unit operations of its industrial processes are old and broad in literature. However, the industrial process itself has changed very slowly over the years, ...
Recuperação de metais a partir da lama vermelha
(Universidade Federal de São Carlos, 2015-08-25)
This paper describes an integrated process for recovering aluminum, iron, titanium, sodium and silica from red mud through a hydrometallurgical treatment sequence. The disposal of red mud, which is the largest waste produced ...
Estudo de métodos para a dispersão de nanopartículas de níquel e ferro em suspensão
(Universidade Federal de São Carlos, 2015-04-27)
In recent decades, several studies have been conducted on the generation of materials at the nanoscale, not only by offering possible risks when inhaled, but also by the various applications that can be employed. Among the ...
Estudo do efeito eletrostático na filtração de partículas de cimento em filtros de mangas
(Universidade Federal de São Carlos, 2015-04-30)
Nowadays the control of industrial pollution is essential. Through filtering, you can remove
the suspended solids in gases. It has been need for more efficient methods for gas filtration in

Produção otimizada de 1,3-propanodiol, ácido propiônico, etanol e hidrogênio, a partir de glicerol bruto e cultura mista, em reator anaeróbio de leito fluidificado
(Universidade Federal de São Carlos, 2016-03-18)
This study aimed to optimize the production of hydrogen and other metabolites using
crude glycerol as substrate, through design of experiments (DoE) and statistical process
optimization. The first study aimed at optimizing ...
Estudo da força de adesão de tortas de filtração de gases em diferentes condições operacionais
(Universidade Federal de São Carlos, 2010-03-08)
Gas filtration is one of the most important methods used in gas-solid separation. During a filtration process, a gas containing an amount of solid particles passes through a porous filter medium which retains the particles. ...
Hidrólise e fermentação do bagaço de cana-de-açúcar em escala de bancada para produção de etanol 2G
(Universidade Federal de São Carlos, 2011-08-26)
The objective of this work was to evaluate the hydrolysis and alcoholic fermentation stages of the sugar cane bagasse (SCB) for second generation ethanol production (2G). Hydrolysis experiments were carried out employing ...
Modelo de contribuições de grupos aplicado a reações para a formação do biodiesel
(Universidade Federal de São Carlos, 2010-02-23)
The interest in biofuels has increased substantially in recent years due, mainly, to reduced damage to the environment compared to conventional fuels derived from petroleum. Accordingly, biodiesel has been studied by ...
Estudo sobre a síntese de zeólitas sodalíticas utilizando planejamento de experimentos
(Universidade Federal de São Carlos, 2011-03-09)
Through the synthesis conditions used were possible to exploit different variables in order to obtain different zeolitic structures, whose main were those formed from sodalitics units (LTA and FAU). From clear solutions ...
Estudo da cristalização da frutose em diferentes meios
(Universidade Federal de São Carlos, 2010-03-09)
The phenomena of fructose crystal nucleation and growth in different media, and its water and ethanol/water solubility curves, which were the base of this process, were studied through the fructose crystallization process. ...
