Abstract: Dual catalyst was prepared with the co-precipitation method and then applied to the research of hydrogen production from steam reforming process of bio-oil. The effects of temperature, S/C ratio (molar ratio of steam to carbon) and weight hourly space velocity on the reaction process were studied. Comparing with the common steam reforming process, the hydrogen yield and volume fraction of the sorption-enhanced steam reforming process of bio-oil for hydrogen production was significantly increased. As both temperature and S/C ratio increased, hydrogen yield and volume fraction of the sorption-enhanced steam reforming process were elevated first and then reduced slightly, and the temperature corresponding to the highest hydrogen yield decreased significantly compared with the common reforming. At 650℃, when the S/C ratio was 4.5, the hydrogen yield reached the peak value of 87.60%, with the hydrogen volume fraction of 94.75%.
