抄録

A thin-layered catalyst supported on a thermo-conductive metal surface makes it possible to design a compact reactor that doubles in function as a heat exchanger. A Pt/Al₂O₃/Al catalyst was prepared by anodic oxidation (AO) of commercial aluminum in oxalic acid solution followed by hot water treatment in choloroplatinic acid solution. During and after AO, the produced alumina layer was dissolved into the oxalic acid electrolyte. The porosity of the layer increased with the treatment time (pore widening). The final thickness of the alumina layer was controlled by balancing the formation and dissolution rates. The maximum thickness and maximum porosity of the alumina layer were 350μm and 0.79, respectively. The platinum content increased as the thickness and porosity of the alumina layer increased, the maximum Pt content was 15.8g-Pt/m². Platinum dispersion was about 0.5 for all catalysts. The catalytic activity for cyclohexane dehydrogenation increased with the platinum content. The maximum steady state reaction rate was 12mol/(h·m²) at 473K under 0.1atm of cyclohexane.
