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 ...
