摘要： 选用Ce-Ni/Co作催化剂、由醋酸钙煅烧制得的CaO作重整催化剂、CO2吸附剂，进行模拟生物油吸附强化蒸汽重整制氢的研究.实验结果表明:在相同温度、M(S)/M(C)(加入水蒸气的摩尔质量与生物油模化物中碳的摩尔质量之比)条件下，吸附剂的加入有利于提高氢气摩尔分数和氢气产率；添加吸附剂后，随着温度的升高，氢气摩尔分数、氢气产率均呈现先增大后减小的趋势，在700℃时达到最大；随着M(S)/M(C)的增加，氢气摩尔分数先增大后减小，在M(S)/M(C)=9时氢气摩尔分数达到最大，而氢气产率则在M(S)/M(C)超过9后变化不大；随着M(CaO)/M(C)(加入的氧化钙的摩尔质量与生物油模化物中碳的摩尔质量之比)的增加，氢气摩尔分数逐渐增大，达到M(CaO)/M(C)=3后几乎不变，氢气产率则先增大后减小，在M(CaO)/M(C)=3时达到最大；温度=700℃，M(S)/M(C)=9，M(CaO)/M(C)=3为模拟生物油重整制氢的最佳条件，在此条件下氢气摩尔分数、氢气产率分别达到92.2%，84.1%.

Abstract: With Ce-Ni/Co as reforming catalyst and CaO from calcination of calcium acetate as CO2 adsorbent， the sorption-enhanced steam reforming of bio-oil for hydrogen production was studied. The results show that the addition of CO2 sorbent can effectively promote the hydrogen molar fraction and hydrogen yield compared with the case without CO2 sorbent under the same temperature and M(S)/ M (C) ratio (the molar mass of steam to carbon in the model compounds of bio-oil ). When the CO2 sorbent existed， the hydrogen molar fraction and yield increased first，then decreased with the increase of the reforming temperature， and reached the maximum at 700℃. With the increase of M(S)/M(C) ratio， the hydrogen molar fraction increased first，then decreased， and was the largest at the M(S)/M(C) ratio of 9，while the hydrogen yield increased till the M(S)/M(C) ratio reached 9， then changed slightly. With the increase of M(CaO)/M(C) ratio ( the molar mass of calcium oxide to carbon in the model compounds of bio-oil)， the hydrogen molar fraction increased gradually， but changed slightly after the M(CaO)/M(C) ratio reached 3， while the hydrogen yield increased first and then decreased， reached the maximum at the M(CaO)/M(C) ratio of 3. The optimum conditions for steam reforming of bio-oil with CO2 sorption are 700℃， M(S)/M(C)=9 and M(CaO)/M(C)=3， where the hydrogen molar fraction and the hydrogen yield are 92.2% and 84.1% respectively.
