Low temperature steam reforming of ethanol in the temperature range of 200-360 degrees C was studied to maximize the production of H-2. The optimum reaction conditions in presence of a suitable catalyst can produce mainly the desired products H-2 and CO2. Cu/Al2O3 catalysts with six different concentrations ranging from 0 to 10 wt.% Mn, were prepared, characterized and studied for the ethanol-steam reforming reaction. Maximum ethanol conversion of 60.7% and hydrogen yield of 3.74 (mol H-2 / mol ethanol converted) were observed at 360 degrees C for catalyst with 2.5 wt.% Mn loading.
