Design and testing of a microchannel reactor for the PROX reaction [Article]
(Elsevier, 2011)
The different steps for manufacturing a microchannel reactor for the PROX reaction are discussed. Transient Liquid Phase bonding (TLP) using a Ni-B-Si amorphous melt spun is used for joining micromilled Al-alloyed ferritic ...
Selective CO removal over Au/CeFe and CeCu catalysts in microreactors studied through kinetic analysis and CFD simulations [Article]
(Elsevier, 2011)
A kinetic study of the preferential oxidation of CO in H2 rich streams (CO-PrOx) over a cerium-copper oxide (CeCu) and a gold catalyst supported on cerium-iron oxide (Au/CeFe) is presented. The gold catalyst is very active ...
Oxidation of CO over gold supported on Zn-modified ceria catalysts [Article]
(Elsevier, 2011)
A series of Zn-modified ceria solids were prepared by thermal decomposition of the corresponding metal propionates. The formation of segregated ZnO particles on the ceria surface is evidenced for these solids using X-ray ...
Fe-doped ceria solids synthesized by the microemulsion method for CO oxidation reactions [Article]
(Elsevier, 2011)
A series of Ce-Fe mixed oxides as well as the pure oxides were synthesized by the microemulsions method. The solid solution formation was established for all the Fe-doped systems and only a hardly noticeable segregation ...
Preferential oxidation of CO over Au/CuOx-CeO2 catalyst in microstructured reactors studied through CFD simulations [Article]
(Elsevier, 2013)
A computational fluid dynamics (CFD) simulation study of the preferential oxidation of CO (CO-PROX) in microstructured reactors consisting in square and semicircular microchannels coated with anAu/CuOx¿CeO2catalyst is ...
Preferential oxidation of CO (CO-PROX) over CuOx/CeO2 coated microchannel reactor [Article]
(Elsevier, 2012)
The general aspects of the synthesis and characterization results of a CuOx/CeO2 catalyst were presented. In addition the principal steps for manufacturing a microchannel reactor and for the coating of the CuOx/CeO2 catalyst ...
Pt vs. Au in water-gas shift reaction [Article]
(Elsevier, 2014)
This work presents a comparison of the gold- and platinum-based catalysts behavior in the water-gas shift (WGS) reaction. The influence of the support, e.g., its composition and electronic properties, studied in detail by ...
Synthesis and application of layered titanates in the photocatalytic degradation of phenol [Article]
(Elsevier, 2015)
This study proposes a direct synthetic route to single titanate sheets through the mild and versatile conditions of the >chimie douce>. The stages of the production include the complexation of the titanium alkoxide precursor ...
Iron-modified ceria and Au/ceria catalysts for Total and Preferential Oxidation of CO (TOX and PROX) [Article]
(Elsevier, 2010)
Iron-modified ceria supports containing different molar percentages of Fe (0%, 10%, 25%, and 50%) were synthesized by thermal decomposition of the metal propionates. The formation of a Ce-Fe oxide solid solution is evidenced ...
Role of ruthenium on the catalytic properties of CeZr and CeZrCo mixed oxides for glycerol steam reforming reaction toward H2 production [Article]
(Elsevier, 2015)
The effect of ruthenium on the physico-chemical properties of CeZr and CeZrCo mixed oxides for H2 production by glycerol steam reforming reaction has been studied. The combination of in situ Raman spectroscopy under both ...
