Catalytic performance and characterization of Ni-Fe catalysts for the steam reforming of tar from biomass pyrolysis to synthesis gas

Catalytic performance and characterization of Ni/CeO2/ZrO2 and commercial catalyst from Indonesia were investigated in steam reforming of methane. Ni/CeO2/ZrO2 catalyst was prepared using co-impregnation of cerium nitrate and nickel nitrate onto zirconia support material. BET, SEM, EDS, XRD, TPD, TG, and ICP analyses were employed for the characterization of the catalysts. Remarkable catalytic performance of Ni/CeO2/ZrO2 catalyst at 600oC operating temperature and atmospheric pressure of about 74.9% methane conversion was obtained compared to 55.9% using the commercial catalyst. In addition, the presence of cerium in Ni/CeO2/ZrO2 was effective in improving the stability and resistance to coke formation. Less carbon formation was confirmed from the thermo-gravimetric analysis. These results showed that the prepared catalyst is promising in the industrial application which can be used at lower operation temperature for energy saving.

ABSTRACTThe addition of Fe addition with suitable amount to Ni /Al2O3 catalyst showed higher catalytic performance than corresponding monometallic Ni and Fe catalysts in the steam reforming of tar from the pyrolysis of cedar wood. Characterization of the catalysts indicates the formation of the Ni-Fe alloys and the surface segregation of Fe atoms on the alloys, and it was also suggested that the structure was almost maintained during the reaction. The surface Fe atoms accept oxygen atom from steam and subsequently supply oxygen species to adsorbed carbonaceous species on neighboring surface Ni atoms, which is connected to the promotion of the steam reforming reaction of tar and the suppression of the coke formation.
