Desempenho de filtros cerâmicos na filtração de gases a altas temperaturas
(Universidade Federal de São Carlos, 2008-09-05)
The creation of rigorous emission and air pollution control standards has led to a growing interest in developing technologies to clean gases that not only remove pollutants efficiently but also recycle the energy produced ...
Biorefinaria de soro de queijo: engenharia de bioprocessos e sistemas aplicada à transformação de um resíduo poluente em produtos com valor agregado
(Universidade Federal de São Carlos, 2008-10-17)
The continuous advances in process computing have provided in recent years several sophisticated tools for process analysis and simulation. The effective use of these tools
demands the capability to interface with a ...
Aplicação de peneiras moleculares contendo cátions orgânicos em catálise básica
(Universidade Federal de São Carlos, 2008-12-12)
This thesis was aimed at studying novel basic catalysts based on molecular sieves containing alkylammonium cations. The studied molecular sieves were faujasite zeolites (FAU) and mesoporous silicate (like MCM-41). The ...
Secagem de sementes de gramíneas (Brachiaria brizantha) em leito fluidizado
(Universidade Federal de São Carlos, 2008-12-05)
Drying operation is an important stage of the processing that precedes the storage of seeds, since that with low moisture contents, these can retain their power of germination and other qualities for long periods. The ...
Isomerização do N-hexano sobre catalisadores Pt-Ni suportados na zeólita H-BEA nanocristalina
(Universidade Federal de São Carlos, 2008-11-11)
This work had as a goal to investigate the main factors that explain the highest activity of zeolite Beta in relation to the other zeolitic structures, using the n-hexane isomerization as a criterion. With this goal, in ...
Estudo do efeito da adição de Au, Pd e Pt em catalisadores Cu/CeO2 aplicados à reação de deslocamento gás-água a baixa temperatura
(Universidade Federal de São Carlos, 2008-07-02)
Cu/CeO2 catalysts doped with Au, Pd or Pt (WGSR) were prepared and applied in water gas shift reaction. The CeO2 support was prepared by four different way: urea co-precipitation-gelation (CeO2-UGC), hydrothermal method ...
Investigação da influência do tamanho das partículas de materiais pulverulentos sobre a força de adesão em diferentes substratos aplicando a técnica centrífuga
(Universidade Federal de São Carlos, 2008-03-25)
It was investigated in this work the influence of the size of the particles of the organic
and inorganic powdery material on the force of adhesion of those particles and a built
substratum of different materials: stainless ...
Preparação e caracterização de derivados de enzimas industriais em quitosana
(Universidade Federal de São Carlos, 2008-04-25)
In this work, several strategies were tested to improve the covalent multipoint attachment of chymotrypsin, carboxypeptidase A and cellulase on chitosan. Hybrid gels with different internal structures were obtained using ...
Liofilização de frutas tropicais
(Universidade Federal de São Carlos, 2008-08-21)
The national and international markets of processed fruits have continually grown due to the improved quality of the marketed product, the convenience of ready-to-serve products and because the availability of seasonal ...
Influência do método de preparação de catalisadores bifuncionais, Pt-Ni/HUSY, na isomerização do n-hexano
(Universidade Federal de São Carlos, 2008-02-25)
Gasoline containing high amount of linear chain compounds have low
octane number. However, this number can be increased when linear alkanes are
subjected to isomerization, able to change linear chain compounds to ...
