The main objective of this study was to monitor and to characterize the particulate
material (PM) with equivalent diameter between 2,5 and 10 µm (PM2,5-10), particulate with
equivalent diameter smaller than 2,5 µm (PM2,5), ...
Operação ótima de reator para síntese enzimática de ampicilina com cristalização simultânea dos produtos
(Universidade Federal de São Carlos, 2007-03-05)
Nowadays, industrial production of semi-synthetic penicillins requires low
temperatures, organochloride solvents and yields a great amount of non-recyclable wastes.
During the last decades, concerns about environmental ...
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, ...

(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 ...
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 ...
