摘要
制备了以La、Ba改性的氧化铝为载体的Ni基催化剂。采用BET ,XRD ,H2 - TPR等表征手段考察了不同载体的催化剂性能 ,并比较了各催化剂对甲烷部分氧化制合成气的反应活性和选择性。结果表明 ,添加La制得的改性氧化铝有较大的比表面积和较大的孔容孔径 。
The Ni based catalysts supported on La, Ba modified alumina were prepared and their properties were studied by BET, XRD and H 2 TPR. The activity and selectivity of these catalysts to the reaction of partial oxidation of methane to synthesis gas were also investigated. The results showed that La modified alumina have larger surface area and the biggest pore volume and pore diameter .The catalyst supported on it displayed the best activity and selectivity for catalytic partial oxidation of methane to synthesis gas when reacted at high temperature.
