摘要：Various Ni-Co bimetallic catalysts were prepared by incorporating sol-gel and wet impregnation methods. A laboratory-scale fixed-bed reactor was employed to investigate their effects on hydrogen production from steam reforming of bio-oil. The catalyst causes the condensation reaction of bio-oil, which generates coke and inhibits the formation of gas at temperatures of 250?degrees C and 350?degrees C. At 450?degrees C and above the transformation of bio-oil is initiated and gaseous products are generated. The catalyst also can promote the generation of H2 as well as the transformation of CO and CH4 and plays an active role in steam reforming of bio-oil or gaseous products from bio-oil pyrolysis. The developed 3Ni9Co/Ce-Zr-O catalyst achieved maximum hydrogen yield and lowest coke formation rate and provided a better stability than a commercial Ni-based catalyst.
