摘　　要：以CeO_2为载体,制备了负载型复合Ni Fe/CeO_2催化剂,用于乙二醇的水相重整制氢.利用N_2吸附脱附(N_2 adsorption-desorption)、X-射线衍射(XRD)和H2化学吸附(H_2 temperature program reduction)对催化剂的结构进行了表征,并考察了Ni/Fe摩尔比对乙二醇水相重整制氢效果的影响以及催化剂的可重复使用性.实验结果表明:在Ni_1Fe_2/CeO_2催化剂上的乙二醇水相重整制氢反应中,H_2选择性为89.27%,,乙二醇转化率为99.13%,,烷烃选择性为11.43%,;催化剂重复使用5次以后,仍然保持初始活性的65%,左右.The composite catalyst NiFe/CeO2, utilized in the hydrogen production by the aqueous-phase reforming of ethylene glycol,was prepared using CeO2 as support. The structure of the prepared catalyst was characterized by N2 adsorption-desorption,X-ray diffraction (XRD) and H2 temperature program reduction (H2-TPR),and the effect of Ni/Fe mole ratio on the hydrogen production by the aqueous-phase reforming of ethylene glycol was investigated. Additionally,the reusability of the prepared catalyst was evaluated. The experimental results showed that in the aqueous-phase reforming of ethylene glycol,on the catalyst Ni1Fe2/CeO2,the H2 selectivity,the ethylene glycol conversion and alkane selectivity was 89.27%,99.13% and 11.43% respectively. After reuse for five times,the catalytic activity of the reused catalyst was still about 65% of its original catalytic activity.
