摘要：A 17.9 wt.% Ni/Al(2)O(3)/alloy catalyst with porous anodic alumina Support was Subjected to steam reforming of methane after 700 degrees C steam purging and no reactivity was shown because of surface oxidation of sintered Ni particles. When 0.05 wt.% Ru doped on this catalyst, it exhibited self-activation and self-regenerative activity, resulted from the hydrogen spillover over Ru and/or Ru-Ni alloy. Moreover, a 97% CH(4) conversion was kept for 20 h over the Catalyst Under electrical heating pattern. (C) 2008 Elsevier B.V. All rights reserved.
