Estudo das propriedades estruturais dos catalisadores de Cu e Cu-Ce suportados em alumina aplicados à reação de deslocamento gás-água
(Universidade Federal de São Carlos, 2013-03-12)
Particle size effect and Ce addition on the catalytic properties of Cu/Al2O3catalysts were investigated for the water gas shift reaction (WGS). The catalysts were prepared by dry impregnation of an aqueous solution of ...
Filtração de gases a altas pressões
(Universidade Federal de São Carlos, 2012-10-31)
The filtration of gases is an important industrial operation with the primary aim of removing unwanted solid particles contained in a gas. The filtration of gases at high pressures is an operation widely used in natural ...
Estudos sobre a síntese da zeólita Beta na presença de íons fluoreto
(Universidade Federal de São Carlos, 2013-02-27)
One alternative to increase the octane rating of gasoline without the use of toxic or polluting compounds, banned by environmental legislation, is the transformation of linear paraffins of low octane number into branched ...
Reação de deslocamento gás-água em catalisadores de platina suportados em TiO2-CeO2
(Universidade Federal de São Carlos, 2012-03-29)
In this work platinum catalysts supported on CeO2, TiO2, TiO2-CeO2 were prepared for application in water gas shift reaction also called Shift or well known by the letters WGSR - Water Gas Shift Reaction. The mixed titanium ...
Simulação dinâmica do processo de destilação de bioetanol em simulador baseado em equações (EMSO)
(Universidade Federal de São Carlos, 2012-07-31)
Distillation of hydroalcoholic mixtures that result from the fermentative route of production of ethanol has been widely studied. Nonetheless, three points have not deserved special attention yet: the industrial fermentation ...
