Hydrogen production from biomass gasification via steam reforming can be introduced as one of the most attractive methods for overcoming energy challenges. In this study, the gasification of bagasse process in the presence of steam performed in fixed bed reactor under 850˚C and atmospheric pressure has been conducted in two stages of noncatalytic and catalytic. To evaluate the effect of active metal particles size, Ni12%-Fe6%/γ-Al2O3 bimetallic nanocatalysts were prepared through microemulsion and impregnation methods. The chemical and physical properties of the nanocatalysts were characterized by TPR, XRD, TEM, and BET techniques. The microemulsion technique especially at the lowest Water/Surfactant (W/S) ratio caused synthesis of the active metal average particle size and increased dispersion on the support. Using the microemulsion technique especially at lower W/S increased the hydrogen yields by a factor of 2.8. Also, Ni-Fe/γ-Al2O3 catalyst promoted by 1 percentage of ruthenium, increased the hydrogen yields by a factor of 3.8 compared to the noncatalytic process.
