摘　　要：利用固定床反应器对一系列自制催化剂Ni/CeO2-ZrO_2和商业镍基催化剂Z417在生物油水溶性组分重整制氢反应中的催化性能进行考察,研究了活性金属Ni的负载量、反应温度、水油比对催化剂活性的影响。实验结果表明:Ni负载量为12wt%的催化剂Ni/CeO2-ZrO2在生物油水溶性组分重整制氢反应中表现出最佳催化活性,当反应温度为800℃和水油比为4.9时,氢产率达到最大值67.8%,氢的选择性较高,为61.8%。Catalytic generation of hydrogen by steam reforming of bio-oil aqueous fraction over a series of self-made Ni/CeO2-ZrO2 catalysts and commercial nickel-based catalysts （Z417） was studied in a bench scale fixed-bed reactor. Effects of water to bio-oil ratios, reaction temperature, and the loaded weight of Ni on the performance of Ni/CeOe-ZrO2catalysts were examined. The results shown that the Ni/CeO2-ZrO2 catalyst with Ni loaded weight 12% was superior to other catalysts. Under the conditions of water to bio-oil ratio 4.9 and reaction temperature 800℃ , H2 yield reaches the highest of 67.8% and H2 selectivity of 61.8% were obtained
