The use of catalyst in the biomass gasification is effective to elevate hydrogen content and to reduce tar formation. This study presents the development of 2.5-10 wt% catalysts for biomass gasification to hydrogen. The catalysts were prepared using incipient wetness impregnation method. Different characterization methods such as Powder XRay Diffraction (XRD), Temperature Programmed Reduction (TPR), adsorption-desorption isotherm and Field Emission Scanning Electron Microscopy (FESEM) were used to characterize the prepared catalysts. BET analysis clearly indicates that catalysts are mainly nonporous and the surface area of the catalysts increases with increasing of Fe loading. Characterization by XRD exhibited the formation of a solid solution of iron-cerium oxide, with the presence of cubic structure which is in agreement with FESEM images. The TPR results show the emergence of two reduction peaks, corresponding to the surface and bulk reduction of to . No distinct peak related to the reduction of to , instead a shoulder evolved, related to the reduction of to Fe.
