A new 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.
