WGS and CO-PrOx reactions using gold promoted copper-ceria catalysts: “bulk CuO-CeO2 vs. CuO-CeO2/Al2O3 with low mixed oxide content”
(Elsevier, 2016)
A copper-ceria bulk catalyst has been compared to a series of catalysts designed according to the as called “supported approach”, corresponding to the dispersion of low content mixed copper-ceria oxide on alumina matrix. ...

Growth of Carbonaceous Nanomaterials over Stainless Steel Foams. Effect of Activation Temperature
(Elsevier, 2016)
Some of the problems that occur during the operation of chemical reactors based of structured catalytic substrates, as monoliths, foams, membranes, cloths, fibres and other systems, are related to the preparation of long ...

Intensifying glycerol steam reforming on a monolith catalyst: a reaction kinetic model
(Elsevier, 2016)
In this work, a structured monolithic catalyst has been tested under a wide range of conditions (partial pressure, residence time, temperature and time-on-stream), with the aim of modeling its kinetic behavior and assessing ...

Ru–Ni Catalyst in the Combined Dry-Steam Reforming of Methane: The Importance in the Metal Order Addition
(Springer Verlag, 2016)
Biogas is one of the main biomass-energy resources. Its use for syngas production with a H2/CO ratio close to two would have huge environmental, social and economic impact in the actual energetic scenario. However, the use ...

O2-assisted Water Gas Shift reaction over structured Au and Pt catalysts
(Elsevier, 2016)
Platinum and gold structured catalysts were compared as active phases in classical and O2-assisted Water Gas Shift (WGS) reaction. Both metals were supported on iron-doped ceria mixed oxide and then, structured on metallic ...

The role of Au, Cu & CeO2 and their interactions for an enhanced WGS performance
(Elsevier, 2016)
The WGS reaction over multicomponent Au/Ce1-xCuxO2/Al2O3 catalysts is studied in this work. The systems are carefully designed aiming to take advantage of every active phase included in the formulation: gold, ceria and ...

Promoting effect of Sn on supported Ni catalyst during steam reforming of glycerol
(Pergamon Press, 2016)
The promoting effect of Sn on the catalytic performance of supported Ni catalyst in the reaction of glycerol steam reforming was studied. The physico-chemical properties of the prepared samples were investigated by X-ray ...

In-situ Raman spectroscopy study of Ru/TiO2 catalyst in the selective methanation of CO
(Wiley, 2016)
Raman spectroscopic technique has been used to characterize a Ru/TiO2 catalyst and to follow in situ their structural changes during the CO selective methanation reaction (S-MET). For a better comprehension of the catalytic ...

Nanogold mesoporous iron promoted ceria catalysts for total and preferential CO oxidation reactions
(Elsevier, 2016)
Herein, a series of highly efficient gold based catalysts supported on mesoporous CeO2-Fe2O3 mixed oxides for CO elimination reactions have been developed. The materials have been fully characterized by means of XRD, Raman ...
