Avaliação da velocidade de cisalhamento média em biorreator convencional tipo tanque agitado e aerado
(Universidade Federal de São Carlos, 2007-03-12)
In biochemical processes, shear rate ( γ&) in the system is an important variable on design
and operation of bioreactors. Shear can result in damage to the cells and the microorganisms,
taking to the viability loss ...
Estudo de condições operacionais na produção de penicilina G acilase por diferentes microrganismos
(Universidade Federal de São Carlos, 2006-12-20)
Penicillin G acylase (PGA) is an enzyme of major impact in human health for
catalyzing the deacilation of the penicillin G, to yield 6-aminopenicillanic acid (6-
APA), key intermediate in the semi-synthetic antibiotics ...
Influência das condições operacionais na formação e remoção de tortas de filtração de gases
(Universidade Federal de São Carlos, 2007-03-30)
The present work aims to evaluate the influence of some operational variables on the filtration process and cake detachment, and also the patchy cleaning phenomenon. The studied conditions were maximum pressure drop, 20, ...
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 ...
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 ...
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 ...
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 ...
