Abstract: Anew type of the catalyst, LaNiAl₁₁O₁₉ for the methane reforming with carbondioxide was synthesized and evaluated. LaNiAl₁₁O₁₉ has a hexaaluminate structure and cankeep large surface and heat resistance against sintering at high reaction temperature. Ascompared with La₂O₃-Ni/SrAl₁₂O₁₉, in the CH⁴⁺CO₂ reaction, LaNiAl₁₁O₁₉ catalyst displaysa higher catalytic activity, lower coking amount and excellent sintering resistance of Niparticle, due to its stable structure.

Key words: LaNiAl₁₁O₁₉, Ni-catalyst, CH₄ reforming with CO₂
