Dinâmica, otimização e controle de processos de fermentação em estado sólido : desenvolvimento de metodologias em escala laboratorial
(Universidade Federal de São Carlos, 2016-05-04)
Solid-state fermentation is characterized by the growth of microorganisms in absence of free
water. In one hand, it is advantageous because simulates their natural environment, enabling
the use of agro industrial residues ...
Síntese e caracterização de nanocatalisadores de platina suportados aplicados à reação de reforma do metano
(Universidade Federal de São Carlos, 2010-03-05)
Colloidal Nanoparticles of Platinum (Pt-NPs) were obtained by reducing hexacloroplatinic acid with ethylene glycol in the presence of polyvinylpyrrolidone (PVP) as protective agent of the particles. Two methods of synthesis ...
Formação de acetato de etila a partir do etanol sobre catalisadores de Cu/ZrO2: efeito da carga de cobre nas propriedades físicas e catalíticas
(Universidade Federal de São Carlos, 2010-03-10)
The ethanol dehydrocoupling in ethyl acetate distinguishes among the reactions of alcohol transformation in products with higher added value. Due to the possibility of obtaining ethanol from biomass in Brazil, the production ...
Hidrotalcitas de Ni-Mg-Al como precursores de catalisadores para produção de gás de síntese a partir de biogás
(Universidade Federal de São Carlos, 2010-07-29)
Catalysts obtained by thermal decomposition of the precursors with hydrotalcite-like structure [Mg1-xAlx (OH)2]x+ [CO3]x/n. mH2O and [Ni1-x Mg1-xAlx (OH)2]x+ [CO3]x/n. mH2O were prepared, characterized and tested in the ...
Efeito das condições de preparação da [CTA+]-SiMCM-41 na atividade da transesterificação
(Universidade Federal de São Carlos, 2010-02-26)
The hybrid [CTA+]-SiMCM-41 mesoporous material (where CTA+ is the cetyltrimethylammonium cation) was employed as synthesized in the transesterification reaction between ethyl acetate and methanol. This is a model reaction ...
Estudo da geração de nanopartículas a partir da atomização de soluções de cloreto de sódio
(Universidade Federal de São Carlos, 2010-02-22)
Particles of nanometric dimensions are subjected, in recent years, to extensive research all over the world, not only for the possible risks that they cause when inhaled, but also for the wide range of applications and ...
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 ...
Determinação experimental da força de adesão entre partículas e meios filtrantes constituídos de celulose
(Universidade Federal de São Carlos, 2010-05-07)
The influence of particle size, compression velocity, and of the material constituting the substrate on adhesion force between particle and substrate was investigated in this study. The centrifuge technique was applied for ...
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 ...
