Abstract: Continuous-adsorption enhanced bio-oil reforming process can produce hydrogen continuously and efficiently. Granular catalysts were prepared for the reforming process. Their catalytic performances with three different bio-oil models (ethanol， acetone and phenol) were investigated. The operating conditions were fixed as follow: the reforming temperature was 750℃， the mass ratio of water to carbon was 6∶1， and the loading capacity of catalyst was 10cm. The result shows that the addition of nickel can effectively promote the steam reforming reaction. Additives like magnesium， cerium， cobalt， et al can improve catalyst’s performance of anti-carbon-deposition. Mg-Ni/Co was the best nickel-based catalyst according to the experiments with different bio-oil models. In the experiment using simulated bio-oil with Mg-Ni/Co as catalyst， the hydrogen production rates with the three models were over 60%， 70% and 90% ， respectively. Mg-Ni/Co has not only good stability， but also good regeneration performance.
