Abstract

A plate-type anodic-alumina-supported 17.9 wt% Ni catalyst quickly deactivated in daily start-up and shut-down (DSS) steam reforming of methane at 700 °C. When 0.05 wt% Ru or Pt was doped, the catalyst exhibited self-activation, self-regeneration, and self-redispersion. The PtNi catalyst showed better stability than RuNi. Awave-shape PtNi catalyst was prepared, while 3000 h continual and 500-time DSS stability was achieved. Nevertheless, for industrial application, some effort should be made to suppress the catalyst sintering.
