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.
