Nickel-based doped ceria-supported catalysts for steam reforming of methane at mild conditions
(Taylor, 2017-01)
Hydrogen is widely considered a promising green energy vector. It may be produced by steam reforming of methane which may be obtained from renewable resources such as biogas or biomass gasification. Nickel catalysts supported ...
Ni catalysts with Mo promoter for methane steam reforming
(ELSEVIER SCI LTD, 2009)
NiO/Al(2)O(3) catalyst precursors were prepared by simultaneous precipitation, in a Ni:Al molar ratio of 3:1, promoted with Mo oxide (0.05, 0.5, 1.0 and 2.0 wt%). The solids were characterized by adsorption of N(2), XRD, ...
Insight into Ni/Ce1−xZrxO2−δ support interplay for enhanced methane steam reforming
(Pergamon-Elsevier Science Ltd, 2019-02-05)
Nickel catalysts supported in zirconium-doped ceria were optimized for methane steam reforming (MSR) at severe reaction conditions, i.e. low temperature and stoichometric water/methane feed ratio. The solids prepared were ...
Zr-enhanced stability of ceria based supports for methane steam reforming at severe reaction conditions
(Pergamon-Elsevier Science Ltd, 2019-03-02)
Ceria based supports are an interesting choice for methane steam reforming due to their coke precursor's gasification activity and ability to stabilize nickel particles. However, sintering and coking studies with this type ...
Co/Al2O3 catalysts promoted with noble metals for production of hydrogen by methane steam reforming
(ELSEVIER SCI LTD, 2008)
The effect of noble metal addition on the catalytic properties of Co/Al2O3 was evaluated for the steam reforming of methane. Co/Al2O3 catalysts were prepared with addition of different noble metals (Pt, Pd, Ru and Ir 0.3 ...
Study of effectiveness factors with non-uniform catalyst distributions for methane steam reforming
(Springer Netherlands, 2020-07-14)
In the present work, three kinetic expressions for methane steam reforming with different methane and water partial pressures dependence were studied. Methane effectiveness factors were simulated for spherical uniform ...
Steam-methane reforming at low temperature on nickel-based catalysts
(Elsevier, 2013-09)
In this work, we report the activity results obtained in steam-methane reforming (SMR) at 500 and 600 °C using four nickel-based catalysts: (a) Ni/Al2O3 and Ni/SiO2, prepared by incipient wetness impregnation method and ...
Co/Mg/Al hydrotalcite-type precursor, promoted with La and Ce, studied by XPS and applied to methane steam reforming reactions
(ELSEVIER SCIENCE BV, 2009)
Catalysts` precursor of Co/Mg/Al promoted with Ce and La were tested in the steam reforming of methane (SRM). The addition of promoters was made by anion-exchange. The oxides characterization was made by X-ray Photoelectron ...
