An anodic alumina supported Ni–Pt bimetallic plate-type catalysts for multi-reforming of methane, kerosene and ethanol

• We prepared a plate-type Ni catalyst simultaneously active for methane, kerosene and ethanol steam reforming.
• Trace amount Pt was doping to the Ni surface to form NiPt alloy to stabilize Ni.
• 3000 h stationary and 500-time DSS stable activity was observed during methane steam reforming.
• A home-made integrated combustion-reforming reactor was proposed.

An anodic alumina supported Ni–Pt bimetallic plate-type catalyst was prepared by a two-step impregnation method. The trace amount 0.08 wt% of Pt doping efficiently suppressed the nickel particle sintering and improved the nickel oxides reducibility. The prepared Ni–Pt catalyst showed excellent performance during steam reforming of methane, kerosene and ethanol under both 3000 h stationary and 500-time daily start-up and shut-down operation modes. Self-activation ability of this catalyst was evidenced, which was considered to be resulted from the hydrogen spillover effect over Ni–Pt alloy. In addition, an integrated combustion-reforming reactor was proposed in this study. However, the sintering of the alumina support is still a critical issue for the industrialization of Ni–Pt catalyst.
