| 摘 要： | 以Na2CO3为沉淀剂,在pH为9的沉淀条件下,采用并流沉淀法制备催化剂载体,考察了催化剂的活性组分前驱体Ni(NO3)2的焙烧温度(550、650和750℃)对Ni-Cu/ZrO2-CeO2-Al2O3在甲烷自热重整制氢反应的影响,并采用SEM方法表征了催化剂的表面结构。结果表明,Ni(NO3)2的焙烧温度对Ni-Cu/ZrO2-CeO2-Al2O3催化剂上的NiO颗粒分散性及催化剂的低温活性有很大的影响,650℃焙烧生成的催化剂上的NiO颗粒较小,分布均匀,分散性好,在反应温度650～850℃内,该催化剂的活性明显高于焙烧温度为550℃和750℃制备的催化剂。

| Abstract: | Ni-Cu/ZrO2-CeO2-Al2O3 catalysis were prepared by co-precipitation method and nomlal adding method at pH 9 and using NaeCO3 as the precipitant, respectively. The effcct of Ni（NO3）2 calcined temperature on the catalytic performancc of the catalysis for the autothcn＇nal reforming of methane to hydrogen was investigated and the structure of thc catalysts were characterized by SEM. The results showed that the particle sizes and the desperation of NiO were effected by Ni（NO3）2 calcined temperature. The catalyst whose Ni（NO3）2 was calcined at 65℃ showed the best catalytic performance among the three catalysts in the reaction temperature rang of 650-850℃. |
