Influence of the calcination temperature on the activity of hydroxyapatite-supported palladium catalyst in the methane oxidation reaction
(Elsevier, 2020-06-26)
In the present study, a series of four hydroxyapatite (HAP) supported palladium samples, with a Pd loading close to 0.5 %, obtained through their calcination at 773, 873, 973, or 1073 K has been investigated. These samples ...
Bimetallic Ni-Co/Al2O3 Catalysts Derived from Aluminate Spinels for Dry Reforming of Methane
(The Italian Association of Chemical Engineering (AIDIC), 2023-04-20)
Five Ni-Co/Al2O3 catalysts for dry reforming of methane were obtained by high-temperature reduction of mixed Ni-Co spinel aluminates (NixCo1-xAl2O4) synthesised by a precipitation route. The aim of the study was to determine ...
Behaviour of Rh supported on hydroxyapatite catalysts in partial oxidation and steam reforming of methane: On the role of the speciation of the Rh particles
(Elsevier, 2018-03-04)
Rh/hydroxyapatite samples were prepared by impregnation and investigated for the partial oxidation (POM) and steam reforming (SRM) of methane. The catalysts were analysed by BET, XRD, DRS, XPS, H 2 -TPR, TEM, H2 chemisorption, ...
Design, characterization and evaluation of Ce-modified cobalt catalysts supported on alpha alumina in the abatement of methane emissions from natural gas engines.
(Elsevier, 2021-03-22)
This work deals with the optimisation of Ce-promoted Co3O4 catalysts supported on alpha alumina for the oxidation of traces amounts of methane. Ten Co-Ce samples were synthesised by incipient wetness coimpregnation with ...
On the Effect of the Synthesis Route of the Support in Co3O4/CeO2 Catalysts for the Complete Oxidation of Methane
(ACS, 2022-12-06)
Six ceria supports synthesized by various synthesis methodologies were used to deposit cobalt oxide. The catalysts were thoroughly characterized, and their catalytic activity for complete methane oxidation was studied. The ...
Dry reforming of methane over sub-stoichiometric NiAl2O4-mediated Ni/Al2O3 catalysts
(Elsevier, 2023-10-31)
A series of Ni/Al2O3 catalysts were prepared from substoichiometric NiAl2O4 precursors (Ni/Al molar ratio between 0.5 and 0.05) were examined for the dry reforming of methane. The calcined spinel precursors and the ...
