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 ...
Caracterização e secagem de sementes de painço (Setaria italica L.)
(Universidade Federal de São Carlos, 2010-08-20)
In this work were determined the main physicochemical properties of seeds of millet (Setaria italica) and their dependence on the moisture content. The drying of seeds under different conditions was also evaluated in order ...
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 ...
Estudo da secagem de sementes de embaúba em leito fluidizado
(Universidade Federal de São Carlos, 2012-03-08)
Due to the importance of conservation of ecosystems and having Cecropia glaziovi.S as a pioneer species of the Tropical Forests, this plant becomes indispensable in reforestation areas altered wild. The drying operation ...
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 ...
Catalisadores bimetálicos Pt-Fe/CeO2 para a reação de oxidação preferencial do CO
(Universidade Federal de São Carlos, 2010-03-31)
The objective of this work is to study the preferential oxidation (PROX) of carbon monoxide in H2-rich feed streams over Pt-Fe/CeO2 catalysts in a feed gas composed of 3% CO, 1.5% O2, 80% H2, and N2 (for balance). The ...
