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 ...
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 ...
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 ...

Characterization of Ni/SiO2 and Ni/Li-SiO2 catalysts for methane dry reforming
(Elsevier Science, 2005-10)
In this study, catalysts based on nickel (15 wt.%. Ni) supported on SiO2 and silica modified by Li addition (0.1 and 1 wt.%. Li) were characterized for their application in dry reforming with carbon dioxide. Catalysts were ...
Carbon dioxide reforming of ethanol over Ni/Y(2)O(3)-ZrO(2) catalysts
(ELSEVIER SCIENCE BV, 2009)
Supported nickel catalysts of composition Ni/Y(2)O(3)-ZrO(2) were synthesized in one step by the polymerization method and compared with a nickel catalyst prepared by wet impregnation. Stronger interactions were observed ...
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 ...
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 ...
Functional nanostructured catalysts based on the niobates to the dry methane reforming and ethylene homologation reactions
(2013-01-01)
Catalytic activity and selectivity of niobate-based nanostructured materials were investigated. Dry methane reforming (DMR) and ethylene homologation reaction (EHR) were selected as test reactions. KSr 2Nb5O15, Sr2NaNb5O ...
