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 ...

Influence of the preparation method in the metal-support interaction and reducibility of Ni-Mg-Al based catalysts for methane steam reforming
(Elsevier, 2019)
Ni-Mg-Al based catalysts were prepared using different preparation methods (impregnation, impregnation-coprecipitation and coprecipitation) and tested in steam reforming of methane. The differences observed in catalytic ...

Microreactors technology for hydrogen purification: Effect of the catalytic layer thickness on CuOx/CeO2-coated microchannel reactors for the PROX reaction
(Elsevier, 2015)
Two blocks of microreactors composed by 100 microchannels and coated, respectively, with 150 and 300 mg of a CuOx/CeO2 catalyst, were prepared and tested in the preferential oxidation of CO in presence of H2 (PROX). The ...

Chemical CO2 recycling via dry and bi reforming of methane using Ni-Sn/ Al2O3 and Ni-Sn/CeO2-Al2O3 catalysts
(Elsevier, 2018)
Carbon formation and sintering remain the main culprits regarding catalyst deactivation in the dry and bireforming of methane reactions (DRM and BRM, respectively). Nickel based catalysts (10 wt.%) supported on alumina ...

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 ...
