Role of chromium in the stability of Ni/Al2O3 catalysts for natural gas reforming
(Elsevier Science, 2000-08)
Ni/Al2 O3 and Ni–Cr/Al2O3 catalysts prepared with melt salts of Ni and Al (Al/Ni=0.5) were studied by magnetic measurements, electron microscopy and catalytic properties. An increase in the catalytic activity and stability ...
AN INVESTIGATION ON THE PRESENCE OF NiAl2O4 IN A STABLE Ni ON ALUMINA CATALYST FOR DRY REFORMING
(Sociedad Chilena de Química, 2005)
Effect of the catalyst preparation method on the performance of Ni-supported catalysts for the synthesis of saturated amines from nitrile hydrogenation
(Elsevier, 2019-09)
The liquid-phase hydrogenation of butyronitrile to saturated amines was studied on silica-supported Ni catalysts prepared by either incipient-wetness impregnation (Ni/SiO2-I) or ammonia (Ni/SiO2-A) methods. A Ni/SiO2-Al2O3-I ...
Effect of Au doping of Ni/Al2O3 catalysts used in steam reforming of methane: Mechanism, apparent activation energy, and compensation effect
(2019-11-02)
Investigation was made of the effect of addition of Au to 15%Ni/Al2O3 catalysts used in the steam reforming of methane. The addition of Au was performed by impregnation of reduced Ni catalysts. The catalysts were characterized ...
Reforming of a model biogas on Ni and Rh-Ni catalysts: Effect of adding La
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Ni catalysts supported on gamma-Al2O3 modified by Rh and La were prepared and evaluated on the reforming of a model biogas. The catalysts were characterized by EDS, XRD, TPR, XANES and surface area estimation (BET). The ...
Influence of Pt addition to Ni catalysts on the catalytic performance for long term dry reforming of methane
(Elsevier Science, 2012-09)
The influence of Pt addition (in very low concentrations) to a Ni/(10%)/Al 2O 3 catalyst in its catalytic performance during long-term experiments of dry reforming of methane was studied. The monometallic Pt(0.5%)/Al 2O 3 ...
Synthesis of menthols from citral on Ni/SiO2-Al2O3 catalysts
(Elsevier, 2013-01)
The one-pot synthesis of menthols from citral was studied on Ni/SiO2-Al2O3 catalysts containing 3.6%, 8.8% and 11.4% Ni. The yield of menthols increased with the amount of Ni up to 94% on Ni(11.4%)/SiO2-Al2O3, reflecting ...
A semiempirical theoretical study of Ni/α-Al2O3 and NiSn/α-Al2O3 catalysts for CH4 reforming
(Elsevier Science, 2003-08)
In order to investigate the nature of Ni supported on α-Al2O3 and its modification with Sn in methane reforming reactions, a theoretical study was carried out. A molecular orbital approach of the extended Hückel type was ...
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 ...
