摘　　要：采用等体积浸渍法制备了催化剂,研究了Ni/Al2O3,Fe/Al2O3,CoMo/Al2O3和NiCo/Al2O3催化剂对甘油水蒸汽重整制氢反应的催化效果,对催化剂进行BET、TPR、XRD表征,以氢产率为实验指标对催化剂进行了评价。研究结果表明,CoMo/Al2O3催化剂在温度650℃氢产率6.02。NiCo/Al2O3催化剂在温度600℃、水醇比16、液空速0.12 h-1条件下的氢产率为6.08。催化剂活性次序为NiCo/Al2O3>Co-Mo/Al2O3>Ni/Al2O3>Fe/Al2O3。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.
