A series of Ni-Ru bimetallic catalysts over La2O2CO3 are prepared by an impregnation method. The catalytic properties are evaluated in ethanol steam reforming reaction from 350 to 700 °C under atmospheric pressure. Ni-Ru/La2O2CO3 containing 6 wt% Ni and 3 wt% Ru is found to be more efficient, and Ni-La composite oxide could be formed in the catalyst. Ru is more active in the ethanol dehydration reaction to form ethylene than Ni. The presence of Ru could improve the selectivity for hydrogen of Ni catalyst. TG results reveal that Ni-Ru/La2O2CO3 has excellent resistance to carbon deposition.

Hydrogen production by ethanol steam reforming over Ni-Cu/ZnO catalyst in the temperatures range of 250-550°C was studied on a fixed bed reactor. The effects of reaction temperature and water/ethanol molar ratio on hydrogen production were investigated. The structure and surface characteristics of the catalyst were measured by scanning electron microscopy (SEM), X-ray diffraction (XRD) and differential thermal analyzer (TG-DSC). The results show that the Ni-Cu/ZnO catalyst has good catalytic performance with higher hydrogen yield of 4.87molH2/molEtOH reacted. A comparison of hydrogen production from ethanol steam reforming over Ni-Cu/ZnO catalyst with over a commercial catalyst was made in this paper.

Y2O3-ZrO2 support was prepared by two-step precipitation method with ammonia and oxalic acid. A series of Cu-Ni/Y2O3-ZrO2 catalysts were prepared by impregnation method. The catalysts were investigated and then characterized by XRD and SEM results. The activity of catalysts in ethanol steam reforming was studied. The effects of the catalyst composition on the ethanol conversion rate were discussed and the catalysts inactivation phenomenon under the temperature ranging from 673K to 723K was then analyzed. The results show that 1Cu9Ni/1Y9Zr catalyst has higher activity in ethanol steam reforming, over which ethanol conversion rate is higher than 98% under the situation of 623K, while the inactivation of catalysts with Cu/Ni>3/7 at 673K~723K was caused by carbon deposition .

Rh4(CO)12-derived Rh/CeO2 is superior to the other oxide-supported Rh catalysts. Coking is the only cause of catalyst deactivation which affects the catalytic stability of Rh/CeO2. Both CeO2-supported Rh0 and Rh+ may participate in catalysis for ESR.
