Aplicação da lógica fuzzi na produção de penicilina G Acilase em cultivos de Bacillus megaterium
(Universidade Federal de São Carlos, 2003-07-28)
Penicillin G acylase (PGA) is an important enzyme for the pharmaceutical industry. This enzyme has industrial use in the hydrolysis of penicillin G to obtain 6-aminocephalosporanic acid (6-APA), essential intermediate for ...
Catalisadores à base de Mo, NiMo e CoMo suportados sobre y-Alumina ou Al-MCM-41 - Avaliação na hidrodessulfurização do dibenzotiofeno
(Universidade Federal de São Carlos, 2007-04-13)
The effect of the γ Al2O3 synthesized by Sol-Gel method and Al-MCM-41 mesoporous molecular sieves used as supports in the preparation of Mo, NiMo and CoMo catalysts was studied. The activity and selectivity of the ...
Desempenho de filtros fibrosos operando na remoção de partículas nanométricas de aerossóis
(Universidade Federal de São Carlos, 2007-02-28)
The increase in the air pollution in the last decades is causing a strong increase in the
monitoring and control of emissions of particulate matter in the atmosphere, in order to
minimize the problems caused to the ...
Secagem de pêra em secador a microondas
(Universidade Federal de São Carlos, 2003-08-05)
The present work has as main objective the pear drying in three different dryers: convective, microwave and microwave-convective. It is also intended to evaluate the effect of the osmotic dehydration, as pré-treatment, in ...
Estudo do mecanismo eletroforético de coleta na filtração de aerossóis
(Universidade Federal de São Carlos, 2007-05-18)
Previous works have shown that the presence of electrostatic forces in particles significantly affect the performance of a filter, both increasing collection efficiency and reducing pressure drop. Recently, in the Environmental ...
Filtração de gases: estudo da deposição de diferentes tortas de filtração em diferentes meios filtrantes
(Universidade Federal de São Carlos, 2006-06-19)
The particle retention inside a filter medium, after cleaning, significantly improves the
initial pressure drop during the subsequent cycle, that is, the residual pressure drop.
However, the way as these particles ...
Estudo da fluidodinâmica em leito fixo utilizando-se métodos numéricos de solução: escoamento monofásico de ar
(Universidade Federal de São Carlos, 2006-03-09)
Studies accomplished in the structure of tubular fixed beds proved that the porosity in these systems presents an oscillatory behavior along the radial direction. The non-uniformity of the porosity generates a behavior of ...
Contribuições ao estudo da secagem em um leito pneumático vertical
(Universidade Federal de São Carlos, 2004-03-30)
Pneumatic dryers are widely applied in industry, mainly because the transport of particulate material can be performed simultaneously with heating and drying operations. However, the design of such equipment is still based ...
Estudo do comportamento da deposição das partículas de diferentes meios filtrantes
(Universidade Federal de São Carlos, 2008-03-17)
Many studies related to bag filters have focused on minimizing the amount of energy used in the process. Seeking longer filtration cycles, lower frequency of cleaning cycles and a longer filter life, such studies search ...
Influência do alimentador de sólidos na fluidodinâmica do transporte pneumático
(Universidade Federal de São Carlos, 2007-03-13)
Pneumatic transport is an operation where powdery and granular materials are conveyed through a pipeline suspended in a gas flow. It is usually found in several industries segments and it is used as a carrier, such as, in ...
