利用海泡石（SEP）为载体，采用沉淀法制备Ni/SEP和Ni/La-SEP催化剂，其中金属La作为助剂改性海泡石。对催化剂进行XRD、TPR和TEM表征。以苯酚：乙醇摩尔比为1：2的混合物为生物油模型物，考察了催化剂、反应温度、水碳比（S/C）和反应时间对催化重整制氢的影响。结果表明，重整反应温度为650℃及S/C为8~10时，Ni/La-SEP催化剂上氢产率达到最高，为68%；同时，Ni/La-SEP催化剂表现出了良好的稳定性。

Through using sepiolite (SEP) as carrier and lanthanum as auxiliary to modify SEP,the Ni/SEP and Ni/La-SEP catalysts are prepared by precipitation method.The prepared catalysts are characterized by XRD,TPR,TEM and SEM-mapping.Taking the mixtures with a mole ratio of phenol to ethanol being 1:2 as bio-oil model,the effects of catalyst,reaction temperature,ratio of solution to carbon (S/C) and reaction time on the hydrogen production by catalytic reforming are investigated.Results show that H₂ yield can achieve the highest 68% over Ni/La-SEP catalyst when the reaction temperature is 650℃ and S/C is in the range of 8-10.Meanwhile,Ni/La-SEP catalyst also shows excellent stability during the steam reforming.
