Abstract

The Solid-state reaction, sintering and hydrocarbon-removal activities of composite powders in La-Ni-Al₂O₃ system were studied toward their application to heat-stable exhaust catalyst. The different routes with the impregnation technique were applied to prepare the composite powders. X-ray diffraction revealed the following solid-state reactions; γ-Al₂O₃ (+NiO) + La₂O₃ (500°C)→γ-Al₂O₃ (+NiO) + LaAlO₃ (800-1000°C)→γ-Al₂O₃ (+NiO) + LaAlO₃ + NiLaAl₁₁O₁₉ (1000-1100°C). The La-stabilization was effective to retain large surface areas of these composite powders. The C₆H₆ removal activities were compared for the Ni-La-Al₂O₃, heated at 800°C and 1000°C. The catalytic performance depended on microstructures in the La-Ni-A1₂O₃ composite powders from different routes.
