对具有磁铅石结构的Ｓｒ１－ｘＬａｘＮｉＡｌ１１Ｏ１９对甲烷与二氧化碳重整反应的催化活性、积炭量和稳定性进行了研究．不同还原温度下催化剂的ＸＲＤ和催化活性的实验结果表明，金属镍是ＣＨ４＋ＣＯ２重整反应的活性组分，金属镍含量越大，反应活性越高．反应后催化剂积炭量的分析结果说明，在相同镍含量和分散度的情况下，Ｌａ３＋离子对Ｓｒ２＋离子调变，可以降低催化剂的表面酸性，提高催化剂的抗积炭能力．ＬａＮｉＡｌ１１Ｏ１９是一种具有较好催化活性、稳定性和抗积炭性能的催化剂．
The catalytic activity, carbon deposition amount and stability of Sr1-xLaxNiAl11O19 with magnetoplumbite structure on methane and carbon dioxide reforming reaction were studied. The experimental results of XRD and catalytic activity of catalysts at different reduction temperatures show that nickel metal is the active component of the CH4 + CO2 reforming reaction. The larger the nickel content is, the higher the reactivity is. The analysis of the amount of catalyst coke deposition after the reaction shows that under the same nickel content and dispersion, the La3 + ions can modulate the Sr2 + ion, thereby reducing the surface acidity of the catalyst and improving the anti-carbon deposition ability of the catalyst. LaNiAl11O19 is a catalyst with good catalytic activity, stability and anti-carbon deposition.
