Steam reforming of ethanol has been studied using various catalysts. Bi-metallic catalysts which are Cobalt and Iron supported on Aluminium Oxide is one of the candidates for steam reforming of ethanol that is capable to produce hydrogen. Iron loading on Cobalt had a positive effect on promotion of the catalytic activity of steam reforming of ethanol. The combination of Cobalt and Iron gives high stability, longer lifetime and resulted as active metal. The catalyst was prepared using incipient wetness method, with sequential impregnation, co-impregnation and different molar ratio. The precursor was impregnated for 6 hours, dried for 16 hours, calcined at 500°c for 16 hours and have characterized using XRD, SEM and BET. The XRD pattern obtained was compared to analyze the crystalline phase observed in the samples. Result of high intensity of the peak is due to the overlapping of metal with the support catalyst. The SEM micrographs indicate that the alumina is crystalline with a well- defined plane exposed and that both metals coated on the support surface uniformly. From BET, the catalyst surface area and dispersion are shown as functions of metal loading for the various series of impregnation and ratio.
