Ethanol Steam Reforming over La₂O₂CO₃ Supported Ni-Ru Bimetallic Catalysts

Abstract:

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.
