All catalysts were prepared by isovolumetric mpregnation method,and activities of prepared Ni/Al2O3, Fe/Al2O3, CoMo/Al2O3 and NiCo/Al2O3 catalysts were studied for hydrogen production by steam reforming of glycerol. All catalysts were characterized BET, XRD and H2-TPR.The catalysts were evaluated by using hydrogen yield as index. The results show that, the maximum H2 yield(6.02)can be obtained at 650 ℃ with CoMo/Al2O3 catalyst;the maximum H2 yield(6.08) can be obtained with NiCo/Al2O3 catalyst under the conditions of 600℃, steam-methanol ratio 16, WHSV 0.12 h-1;Catalyst activity sequence NiCo/Al2O3>Co-Mo/Al2O3>Ni/Al2O3>Fe/Al2O3.
