Productivity and order versus the superficial behavior of the prox reaction on a copper-ceria catalyst Monte Carlo simulations
(Elsevier, 2016)
Monte Carlo simulations for the productivity and order of the PROX/copper-ceria catalyst reaction with different superficial %Cu are made. The results are correlated with the behavior of the different surface species (CO, ...
Estudo de catalisadores de cobre suportados para a reação de oxidação preferencial do CO
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2010-06-30)
The CO preferential oxidation reaction (PROX-CO) has been widely studied in last few years. Aiming H2 purification for proton-exchange membrane cells (PEMFC) use, the main role of the PROX-CO reaction should be reduce the ...
CuO-CeO2 catalysts synthesized in one-step: Characterization and PROX performance
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
PEM fuel cells seem to be the most affordable and commercially viable hydrogen-based cells, the biggest challenge being to obtain CO-free H-2 (<100 ppm) as the fuel. In this study, the use of CuO-CeO2 catalysts in ...
Estudo de catalisadores bimetálicos de platina ou paládio e cobre suportados em céria para a reação de PROX-CO
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2016-10-13)
In the present work, catalysts were prepared xCuO / CeO2 (x = 1.0 and 3.0% by mass)
doped with Pt or Pd for application in the preferred oxidation reaction of carbon
monoxide, also known as PROX-CO reaction. The catalysts, ...
Catalisadores de Au suportados aplicados à oxidação preferencial do CO : influência da interação entre Au e Fe nos sítios ativos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2017-04-07)
New sources of clean energy have been studied, such as hydrogen (H2). Carbon monoxide, a subproduct of its production, poisons the fuel cell. To reach concentrations below 10 ppm, the addition of preferential CO oxidation ...
Comparative study of the behavior of the prox reaction on a metallic catalyst and a copper-ceria catalyst. Monte Carlo simulations
(Elsevier B.V., 2019)
© 2019 Elsevier B.V.The different qualitative and quantitative behaviors of copper-ceria (dual surface) and supported noble metal catalysts for the PROX reaction are compared. Through Monte Carlo simulations the effect of ...
Effect of Pt-MOx (M = Fe, Co) interaction on the preferential oxidation of CO over Pt/MOx/TiO2 catalysts prepared by selective electrostatic adsorption
(Elsevier B.V., 2019)
In this work, the catalytic properties of Pt/MOx/TiO2 (M = Fe, Co) catalysts prepared by strong electrostatic adsorption (SEA), were investigated for the preferential oxidation (PROX) of CO in H2. The SEA method was chosen ...
Study of CuO/CeO2 catalyst with for preferential CO oxidation reaction in hydrogen-rich feed (PROX-CO)
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The CuO/CeO2 system was investigated as a catalyst for preferential CO oxidation reaction in hydrogen-rich feed (PROX-CO). The catalysts were prepared by deposition-precipitation (DEP) and co-precipitation (COP) methods ...
