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

▶ Addition of the optimum amount of Fe to Ni/Al2O3 enhanced the catalyst activity and stability of Ni/Al2O3 in the steam reforming of tar derived from the pyrolysis of cedar wood. ▶ Fe atoms added were alloyed with Ni and they tended to be located on the surface of the Ni-Fe alloy particles. ▶ Suggested mechanism of high performance in the tar steam reforming is due to the synergy between high tar decomposition activity on Ni atoms and activation of H2O on Fe atoms.
