中文摘要：

利用共沉淀法,制备一系列在凹凸棒土上负载不同含量的NiO-Fe2O3催化剂。以乙酸、乙醇和苯酚的水溶性溶液为生物油模型物,在自制的三段式固定床反应器中,考察了NiO-Fe2O3的负载量、反应温度、水碳比（S/C）对生物油模型物重整制氢的影响。结果表明,所获得的氢气产率最高的工艺条件为,在650℃条件下,以水碳比810的生物油模型为实验原料,使用自制的50%NiO-50%Fe2O3/PG型催化剂,可使气体产物中H2的相对含量达到最大66.15%。

英文摘要：

A series of NiO-Fe2 O3 catalysts loaded on palygouskite were prepared by co-precipitation method and used in the catalytic steam reforming to produce hydrogen in a self-made three-stage fixed bed reactor. The loading of NiO-Fe2 O3 , reaction temperature and ratio of steam to carbon ( S/C) on hydrogen production were investigated, with a water-soluble mixture of acetic acid, ethanol and phenol as the bio-oil model compounds. The results indicated that under the optimum conditions, viz. , 650 ° C, an S/C ratio of 8 ~10 and 50%NiO-50%Fe2 O3/PG as the catalyst, the relative content of H2 reaches 66. 15% in the gaseous product.
