Steam reforming of ethanol, C2H5OH + H2O --> 2CO + 4H(2), was carried
out over Co/Al2O3, Co/SiO2, Co/MgO, Co/ZrO2 and Co IC. The properties
of the Co catalysts were greatly affected by the supports. Co/Al2O3 ex
hibited the highest selectivity for steam reforming of ethanol by supp
ression of methanation of CO and decomposition of ethanol.
