Influência de diferentes materiais suporte na produção de hidrogênio em reator anaeróbio de leito fluidizado
(Universidade Federal de São Carlos, 2009-02-27)
Hydrogen is a clean and renewable source of energy and it is considered the "fuel of the future", because it produces only water during combustion and when it is used as fuel and hydrogen has a high energy yield of 122 ...
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 ...
Fluidodinâmica de leitos fluidizados e vibrofluidizados operando com partículas planas
(Universidade Federal de São Carlos, 2009-03-12)
The use of fluidized beds as a unit operation for drying of particulate materials is common in industrial processes. However, most works published in the literature, focus the drying of uniform particles, in a narrow range ...
Estudo da expressão de lipase BTL2 de Bacillus thermocatenulatus em E. coli recombinante
(Universidade Federal de São Carlos, 2009-04-03)
Using recombinant DNA techniques, the lipase BTL2 gene of Bacillus thermocatenulatus was cloned in E. coli BL321 under control of the strong temperature-inducible λPL promoter. It
was investigated, initially, in this ...
Projeto e construção de bancada para ensaios de filtração de gases a alta pressão
(Universidade Federal de São Carlos, 2009-03-30)
With the industrial expansion and the increase of vehicles assembled daily, there was an increase in the use of natural gas as combustible. Beyond the cheaper the level of emission of pollutants by burning natural gas as ...
