摘　　要：采用共沉淀法制备Ni/HZSM-5、Ni-Fe/HZSM-5、Fe/HZSM-5催化剂,以XRD、BET、SEM为测试方法对其进行表征。在固定床反应器上,以间甲酚为生物油模型物进行水蒸汽催化重整制氢实验,考察了催化剂、反应温度、反应时间、水碳比对水蒸汽催化重整间甲酚制氢的影响。实验结果表明,反应温度650℃,反应时间120 min,水碳比8,使用Ni-Fe/HZSM-5催化剂时氢气产率达到最大,为54%。Ni/HZSM-5,Ni-Fe/HZSM-5 and Fe/HZSM-5 catalysts are prepared by co-precipitation method. XRD,BET and SEM are used for characterization of the resultant catalysts. With m-cresol as bio-oil compound,the hydrogen production via catalytic steam reforming is performed on fixed bed reactor. The influence of catalysts,reaction temperature,reaction time and steam/carbon ratio are explored for the catalytic steam reforming reaction. The best catalytic performance is obtained by using Ni-Fe/HZSM-5 at reaction temperature of 650℃,with the reaction time of 120 min and steam/carbon ratio of 8. Under this condition,hydrogen yield reaches the highest value（ 54%）.
