Supported catalysts for induction-heated steam reforming of methane

Ni60Co40 nanoparticles supported on g-Al2O3 capable of simultaneously catalysing the
steam reforming reaction of methane and supplying in-situ the heat necessary to activate
the reaction by induction heating, have been synthesized and characterized. Energy is
remotely and promptly supplied by an alternating radiofrequency magnetic field (induction
heating system) to supported nanoparticles that act as dissipating agents by virtue of their
ferromagnetic properties. The temperature reached on the NieCo based catalyst surface is

Influence of the catalyst support on the steam reforming performance of toluene as tar model compound

The large amount of tar produced along with the syngas during biomass gasification is one of the major obstacle for the diffusion of gasifiers at industrial scale. Catalytic cracking and reforming are the most suitable processes for the transformation of tar into lighter gases. The selection of suitable catalysts is a critical step. The catalysts must own high activity and high resistance to deactivation for coke deposition.

Steam reforming of model compounds from biomass fermentation over nanometric ruthenium modified nickel-lanthanum perovskites catalysts

Nanometric ruthenium-modified LaNiO3 perovskites prepared by coprecipitation method in aqueous and non-aqueous solvents were tested as catalysts in the steam reforming of butanol, acetone and ethanol and their mixture, named ABE, usually produced by fermentation. ABE is potentially of great interest for hydrogen production, notwithstanding the strong tendency of this mixture of oxygenated compounds to produce coke in the steam reforming conditions. The tested catalyst showed high feed conversions with improved stability.

New synthetic route for the production of mayenite support to enhance Ni resistance to coke deposition in the reforming of tar model compounds

Four nickel/mayenite catalysts were synthesized. Mayenite was prepared from different precursors, namely boehmite (AlO(OH)) + Ca(NO3)2·4H2O and gibbsite + Ca(OH)2, for each couple a specific procedure was followed. The effect of the Ni addition method was also evaluated, comparing wet impregnation and direct inclusion of nickel precursor during mayenite preparation. The obtained catalysts were characterized by XRD, BET, SEM/EDS and TPR. The Ni/mayenite catalysts were tested in steam reforming of toluene and pyrocatechol, chosen as tar model compounds.
