Prox-regularity approach to generalized equations and image projection
(EDP Sciences, 2018-04)
In this paper, we first investigate the prox-regularity behaviour of solution mappings to generalized equations. This study is realized through a nonconvex uniform Robinson Ursescu type theorem. Then, we derive new significant ...
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, ...
Smoothness of the metric projection onto nonconvex bodies in Hilbert spaces
(Academic Press Inc., 2018)
Based on a fundamental work of R. B. Holmes from 1973, we study differentiability properties of the metric projection onto prox-regular sets. We show that if the set is a nonconvex body with a Cp+1-smooth boundary, then ...
Discontinuous sweeping process with prox regular sets
(EDP Sciences, 2017)
In this paper, we study the well-posedness (in the sense of existence and uniqueness of a solution) of a discontinuous sweeping process involving prox-regular sets in Hilbert spaces. The variation of the moving set is ...
CO preferential oxidation (CO-PROx) on La(1-x)Ce(x)NiO(3) perovskites
(ELSEVIER SCIENCE BV, 2011)
La(1-x)Ce(x)NiO(3) perovskites have been prepared, characterized by XRD. TPR and surface area and tested as catalysts for CO-PROx, with a feed of 2.5% CO, 5% O(2), 33% H(2) and N(2) to 100%. The samples exhibited an XRD ...
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 ...

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 ...
