Desempenho de meios filtrantes na filtração de gases a altas pressões
(Universidade Federal de São Carlos, 2011-09-21)
The presence of residue in the transport of natural gas in pipelines may result in numerous losses for the gas companies, such as obstruction of measuring equipment, decrease in product quality, and reduction in the lifetime ...
Desenvolvimento de tecnologia para extração e recuperação de polihidroxialcanoatos obtidos a partir da sacarose de cana-de-açúcar
(Universidade Federal de São Carlos, 2011-11-30)
The main objective of this study was to contribute to the development of a competitive and sustainable process to produce polyhydroxyalkanoates (PHA's) from the fermentation substrate sucrose cane sugar. The study involved ...
Incorporação de titânio na peneira molecular Mor e suas propriedades.
(Universidade Federal de São Carlos, 2003-08-14)
The titanium incorporation in the MFI structure generated a new material, called TS-1, which showed highly active in oxidation reactions of organic compounds. A very important aspect in this titanium-silicate is that it ...
Estudo da alimentação de sólidos em sistemas de transporte pneumático
(Universidade Federal de São Carlos, 2011-03-03)
One of the most important parts in a pneumatic conveying is the solids feeding system due its complexity fluid dynamic, besides affecting the operational stability, economical and technical feasibility and system efficiency. ...
Síntese enzimática de ampicilina em reator integrado.
(Universidade Federal de São Carlos, 2004-02-11)
Enzymatic route to produce antibiotic acts in mild reaction conditions
(aqueous medium, neutral pH and moderate temperatures). Furthermore it reduces
the number of reaction steps and decreases the amount and toxicity of ...
Simulação de um alimentador Venturi em trecho ascendente no transporte pneumático de sólidos
(Universidade Federal de São Carlos, 2012-08-30)
The radial and axial distributions of coarse solids when fed directly in a riser are unknown, despite this type of feeding is very important for drying and preheating of solids during conveying. In this context, this thesis ...
Determinação da carga eletrostática em aerossóis e seu efeito na filtração de gases.
(Universidade Federal de São Carlos, 2005-05-06)
It has been shown that the presence of electrostatic charges in particles affects
significantly the performance of a filter, both increasing collection efficiency and reducing
pressure drop. The aim of the present work is ...
Diferentes meios de cultivo e condições operacionais na produção de penicilina G acilase por Bacillus megaterium.
(Universidade Federal de São Carlos, 2007-08-16)
Penicillin G acylase (PGA) is an important enzyme for industry, used to produce
aminopenicillanic acid, a key intermediate in the synthesis of ampicillin, among other betalatam
antibiotics. The production of this enzyme ...
Reator enzimático de membrana para proteólise de soro de queijo, visando à produção de concentrado protéico com baixo teor de fenilalanina
(Universidade Federal de São Carlos, 2007-12-07)
Enzymatic hydrolyzed proteins present some advantages over the pool of
amino acids obtained after a chemical hydrolysis: lower osmolality (easier absorption by the
organism) and better sensorial characteristics. The removal ...
Propriedades estruturais e eletroquímicas de espinélios de lítio e manganês dopados para uso em baterias de lítio.
(Universidade Federal de São Carlos, 2005-09-01)
The spinels investigated in the present work
were obtained by solid state reaction at 750 ºC for 72 h among the precursors
ε-MnO2, LiOH and the respective oxides/salt of the doping ions. In order to control
the particles ...
