Catalisadores à base de Cu, Zn, Al e Ce aplicados à reação deslocamento gás-água
(Universidade Federal de São Carlos, 2014-03-26)
The water gas-shift reaction (WGS) is an important step in the production process and purification of H2 from hydrocarbon. Commercially, to overcome the thermodynamic and kinetic limitations, this reaction occurs in two ...
Produção de hidrogênio em reator anaeróbio de leito fluidizado a partir de glicerol bruto sob condições termofílicas
(Universidade Federal de São Carlos, 2014-03-25)
This study aimed to evaluate the influence of the hydraulic retention time (HRT) on hydrogen production using crude glycerol as a substrate in an anaerobic fluidized bed reactor (AFBR ) . The reactor had a volume of 1979 ...
Controle preditivo não linear para sistemas de parâmetros distribuídos
(Universidade Federal de São Carlos, 2014-08-28)
In general, the chemical processes can be represented using mathematical models, in the case of lumped systems include ordinary differential equations, or, partial differential equations, when distributed parameter systems ...
Análise da eficiência energética e otimização de secadores rotativos
(Universidade Federal de São Carlos, 2014-02-25)
Energy Efficiency and optimization of dryers are research areas with environmental concerns. These areas have the increasing need to improve the energy performance of processes through to quality improvement and reduction ...
Reator airlift operado em sobrepressão: construção, caracterização da transferência de oxigênio e aplicação em cultivos de Escherichia coli recombinante
(Universidade Federal de São Carlos, 2014-08-15)
Owing to the broad biochemical, physiological and genetic characterization and the ease of manipulation and cultivation, several proteins with therapeutic and industrial applications are produced by genetically modified ...
Avaliação do desempenho de um ciclone stairmand adaptado com bicos injetores de água
(Universidade Federal de São Carlos, 2014-03-28)
The collection efficiency and costs of implementation and operation are the main factors considered in the use of equipment for the separation of particulate matter in the gas. The cyclone is commonly employed industrially ...
Produção de etanol a partir de xilose com glicose isomerase e Saccharomyces cerevisiae coimobilizadas em gel de alginato
(Universidade Federal de São Carlos, 2013-06-20)
In this work, it was studied the simultaneous isomerization and fermentation of xylose to ethanol (SIF) using xylose isomerase (XI) and S. cerevisiae co-immobilized in calcium alginate gel. XI was immobilized on chitosan ...
Modelagem e simulação de uma destilaria autônoma de produção de etanol de primeira geração (E1G)
(Universidade Federal de São Carlos, 2014-03-24)
Most of the operations in an autonomous distillery for production of ethanol are carried on in a continuous fashion. The fermentation stage, however, may be projected to work either continously or semicontinuously. The ...
Influência de aspectos geométricos na hidrodinâmica e transferência de oxigênio de biorreatores airlift de circulação interna
(Universidade Federal de São Carlos, 2014-02-28)
The performance of pneumatic bioreactors is highly related to their geometric characteristics, such as the bottom clearance, riser to downcomer cross sectional area ratio, liquid height and the gas-liquid separator design. ...
Modelagem e simulação em plantas de etanol: uma abordagem técnico-econômica
(Universidade Federal de São Carlos, 2013-07-26)
The ethanol (fuel grade and anhydrous) is, fundamentally, the most relevant global biofuel nowadays, in energy, environmental, economic and technological terms. This scenario brings up the Brazilian ethanol, made from ...
