Design and testing of a microchannel reactor for the PROX reaction
(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 ...

Monitoring the Reaction Mechanism in Model Biogas Reforming by In Situ Transient and Steady-State DRIFTS Measurements
(Wiley-VCH, 2017)
In this work, the reforming of model biogas was investigated on a Rh/MgAlO catalyst. In situ transient and steady-state diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) measurements were used to gain ...

Boosting the activity of a Au/CeO2/Al2O3 catalyst for the WGS reaction
(Elsevier, 2015)
Herein a strategy to design highly efficient Au/CeO2/Al2O3 based WGS catalysts is proposed. The inclusion of transition metals, namely Fe, Cu and Zn as CeO2 dopant is considered. All the promoters successfully increased ...

Selective CO methanation with structured RuO2/Al2O3 catalysts
(Elsevier, 218)
Active and selective structured RuO2/Al2O3 catalysts for CO methanation using a flow simulating CO2-rich reformate gases from WGS and PROX units (H2 excess, CO2 presence and 300 ppm CO concentration) were prepared. Both, ...

Oxidation of CO over gold supported on Zn-modified ceria catalysts
(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 ...

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 ...

H2 oxidation as criterion for PrOx catalyst selection: Examples based on Au-CoOx-supported systems
(Elsevier, 2015-06-01)
A new approach for understanding PrOx reaction over gold catalysts is proposed in this work. The competition between H2 and CO oxidation has been studied over a series of Au/MOx/Al2O3 (M = Ce and Co) catalysts in simulated ...
