Abstract

A novel plate-type anodic alumina supported 17.9 wt% Ni/Al ₂O₃/alloy showed a quick deactivation in daily start-up and shut down (DSS) steam reforming of methane (SRM) at 700 °C, because of the Ni oxidation reaction with steam. When 0.078 wt% Pt was doped, the catalyst exhibited self-activation and self-regeneration ability, while 3000 h continual and 500-time DSS stability was testified. Further, this Pt-Ni catalyst also showed excellent reactivity during carbon dioxide reforming of methane (CMR) and partial oxidation of methane reaction (POM). According to the TPR and XRD analyses, the H₂ spillover effect and the formation of Pt-Ni alloy were believed to be the main reason for the reactivity improvement of this catalyst.
