采用浸渍法制备了SiO2,γ-Al2O3,CaO和TiO2负载的Ni催化剂,以及不同MgO含量的MgO-7.5％ Ni/γ-Al2O3催化剂,利用X射线衍射和N2吸附-脱附技术表征了催化剂的结构,在固定床反应器上评价了它们在稻草水蒸气催化重整制合成气反应中的催化性能,考察了反应条件对催化剂性能的影响.结果表明,以γ-Al2O3为载体时Ni催化剂活性最高,其中7.5％ Ni—-Al2O3催化剂的H2收率可达1071.3ml/g,H2∶CO的体积比为1.4∶1;同时,MgO的添加进一步提高了该催化剂的性能,当MgO含量为1.0％时,H2收率可达1194.6ml/g,H2∶CO体积比可达3.9:1.可见MgO的加入促进了Ni基催化剂上稻草水蒸气催化重整制合成气反应的进行,同时使得合成气中CO发生水-汽转换反应,从而大大提高了合成气中H2含量.
