Surface Decomposition of Doped PrBaMn₂O_5+δ Induced by <i>In Situ</i> Nanoparticle Exsolution: Quantitative Characterization and Catalytic Effect in Methane Dry Reforming Reaction

Investigation of the catalytic performance and coke formation of nanocrystalline Ni/SrO-Al2O3 catalyst in dry reforming of methane

In this study, nickel catalysts supported on mesoporous nanocrystalline gamma alumina promoted by various strontium contents were prepared by the impregnation method and employed in dry reforming of methane (DRM). The prepared catalysts were characterized using N2 adsorption (BET), temperature-programmed reduction and oxidation (TPR,) and oxidation (TPDTPO), X-ray diffraction (XRD), and scannin...

Dry reforming of methane under an electro-catalytic bed: effect of electrical current and catalyst composition

Dry reforming of methane (DRM) has been investigated under an electronactivated catalytic bed in a thermo-electrical reactor. The main objective of this work was to investigate what the impact of the electrical current on the conversion of methane is. The combination of thermal and electrical energy allowed achieving higher conversions for both reactants at temperatures varying from 850–950°C. ...

Dry Reforming of Methane Using Cold Plasma; Kinetic Model Study

In this work, the dry reforming of methane was studied using a corona and gliding discharge plasma microreactors. A chemical kinetic model was developed to describe the experimental behavior observed. The kinetic model is proposed based on the assumption that the reactant molecules CH4 or CO2 are attacked by active species produced b...

An Investigation into the Effect of Hydrotalcite Calcination Temperature on the Catalytic Performance of Mesoporous Ni-MgO-Al2O3 Catalyst in the Combined Steam and Dry Reforming of Methane

Several mesoporous nickel-based catalysts with MgO-Al2O3 as the catalyst support were prepared using a co-precipitation method at a constant pH. The supports were prepared from the decomposition of an Mg-Al hydrotalcite-like structure which had already been prepared with Mg/Al=1. Prior to impregnating 10 wt.% nickel on the supports, the precursor was decomposed at several ...
