Abstract:
？采用共沉淀-浸渍法并在较低温度(400~700oC)下焙烧制备了镁铝混合氧化物(MgmAl)负载的Ni催化剂.X射线衍射和程序升温还原结果表明,Ni物种高度分散于催化剂表面,没有形成尖晶石NiAl2O4.在650oC可被还原成金属Ni纳米晶粒,在400oC和较低水/碳摩尔比(S/C=2)条件下表现出较好的催化液化石油气(LPG)重整反应性能.详细考察了Mg/Al摩尔比、Ni负载量、载体和催化剂的焙烧温度对催化剂活性和稳定性的影响.结果表明,由500oC焙烧的Mg1.25Al载体负载的15%Ni催化剂,并于500oC焙烧时,在LPG重整反应中表现出最优的性能,尽管它比高温(≥800oC)焙烧制备的Ni/MgmAl催化剂更易积炭,催化活性和稳定性有所下降,但由于还原温度较低,在交通和小规模供电的燃料电池领域更具实际应用意义.
