摘要

The performances of Ni-Co/Al_2O_3 catalysts with the optimum composition were much higher than the corresponding monometallic Ni and Co catalysts in terms of the catalytic activity, the resistance to coke formation and catalyst life in the steam reforming of biomass tar. This behavior can be related to the formation of the Ni-Co solid solution alloys indicated from the characterization with XRD, TPR, TEM, H_2 adsorption and EXAFS.
