以HZSM-5为载体，采用浸渍法制备Co/HZSM-5、Fe/HZSM-5、Co-Fe/HZSM-5催化剂，并对其进行XRD、BET、SEM、TG表征分析。选取乙酸、乙二醇、苯酚和丙酮的混合物为混合型生物油模型物，考察催化剂、温度、S/C、WHSV等因素对水蒸汽催化重整混合型生物油模型物制氢的影响。结果表明，在Co-Fe/HZSM-5催化剂上，温度为650℃，S/C为10，WHSV为2 h^-1时，氢气产率最大，约为57%。

Co/HZSM-5,Fe/HZSM-5 and Co-Fe/HZSM-5 catalysts are prepared by impregnation method using HZSM-5 as support.The prepared catalysts are then characterized by XRD,BET,SEM and TG.Taking the mixtures of acetic acid,ethylene glycol,phenol and acetone as model compound of hybrid bio-oil,the influences of catalysts,temperature,the ratio of steam to carbon and weight hourly space velocity (WHSV) on the hydrogen production through catalytic steam reformation of the model compounds are investigated over Co-Fe/HZSM-5 catalyst in fixed bed reactor.The results indicate that the hydrogen yield reaches the maximum value,about 57% when Co-Fe/HZSM-5 catalyst is used,temperature is 650℃,S/C is 10,WHSV is 2 h^-1.
