Desempenho de meios filtrantes na remoção de partículas nanométricas de aerossóis
(Universidade Federal de São Carlos, 2009-03-12)
The interest of studies on the development of techniques for removal of particles in the nanosized scale was promoted by concern about air quality and human health, in addition to restrictions on the control of ultrafine ...
Estudo da influência do formato das partículas na operação de filtração de gases
(Universidade Federal de São Carlos, 2009-09-01)
Particle morphology is a parameter which deserves great attention in industrial processes. This parameter affect some processes and products like medicines production and cosmetics which are developed by the compaction ...
Desempenho de um precipitador eletrostático operando na remoção de nanopartículas de aerossóis
(Universidade Federal de São Carlos, 2009-09-16)
The removal of ultrafine particles is becoming an increasingly important operation due to the occupational problems caused to the environment and to the human health, such as inhalation of particulate matter, as well as ...
Catalisadores de Co/Al2O3 para reforma a vapor do etanol: estudo do efeito do método de preparação
(Universidade Federal de São Carlos, 2009-08-11)
Alumina supported cobalt catalysts were prepared, characterized and applied in ethanol steam reforming for hydrogen production. The support and the supported catalysts were prepared, respectively, by the solvothermal and ...
Simulação e controle do processo de produção de levedura
(Universidade Federal de São Carlos, 2009-03-27)
The yeast Saccharomyces cerevisiae can be useful in several ways in bioprocesses. It is widely used in anaerobic processes for production of bioethanol at Brazilians plants. It is also of great importance as baker s yeast, ...
Desenvolvimento de catalisadores para reforma e oxidação combinadas do metano
(Universidade Federal de São Carlos, 2009-03-20)
In this work, we studied the effects of the promoters of support (ZrO2, La2O3, CeO2, CeO2-ZrO2, CeO2-ZrO2-La2O3 and La2O3) in the nickel catalysts supported on γ-Al2O3 were studied. The supports were prepared by wet ...
Influência do teor metálico na isomerização do n-hexano sobre Ni-Pt/HUSY.
(Universidade Federal de São Carlos, 2003-08-06)
The isomerization of linear alcanes has arised great interest in the industry of refining of oil with the intention to transform n-paraffins (particularly with 6 and 7 carbon atoms), in iso-paraffins, since these last ones ...
