Isomerização de n-hexano sobre Pt-NiHUSY empregando zeolita com alto teor de Al.
(Universidade Federal de São Carlos, 2005-08-03)
The isomerization reactions of linear alkanes are very important to petrochemical industries due to the isomer products in reaction possess high octane number. The majority of the literature articles involves the job ...
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 ...
Avaliação do processo de tratamento biológico de águas residuárias sanitária e industrial em sistema combinado com reator biológico de contato seguido de filtro aerado submerso
(Universidade Federal de São Carlos, 2010-02-22)
This study presents the operational results of a pilot wastewater treatment plant. The assays were carried out in two phases: Phase 1 involved the operation of a rotating biological contactor (RBC), while Phase 2 involved ...
Seleção de suportes e protocolos de imobilização de lipases para a síntese enzimática de biodiesel
(Universidade Federal de São Carlos, 2009-05-25)
The objective of this thesis was to prepare and select immobilized lipase derivatives with high catalytic activity and thermal stability to mediate the biodiesel synthesis from palm and babassu oils by ethanolic route. The ...
Hidrodinâmica e transferência de oxigênio em três biorreatores Airlift de circulação interna geometricamente semelhantes
(Universidade Federal de São Carlos, 2009-03-12)
Internal-loop airlift reactors (ALR) are a special class of pneumatic reactors. The use of this type of reactor has been attractive for chemical and biological reactions because of their simple construction without moving ...
Modelo matemático do processo de purificação do ácido clavulânico por troca iônica em coluna de leito fixo
(Universidade Federal de São Carlos, 2009-08-04)
Clavulanic acid (CA) is a β-lactam antibiotic produced industrially by submerged cultures of the filamentous bacterium Streptomyces clavuligerus. Due to its importance, several studies on the purification of clavulanic ...
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 ...
Síntese e avaliação de sílica tipo M41S contendo cátions CTA em transesterificação catalítica
(Universidade Federal de São Carlos, 2010-08-13)
The investments in the biofuel production have increased a lot in the last years mainly because of smaller damages they cause to the environment in comparison with the derived conventional petroleum fuels. The reaction of ...
