基于双效催化剂的生物油吸附强化重整实验

制备了镍基双效催化剂，并将其应用在多组分生物油模化物吸附强化重整制氢的研究中，考察了重整温度、水碳比、液体质量空速对反应过程的影响.结果表明，在双效催化剂作用下，吸附强化重整阶段获得的氢气体积分数和氢气产率较普通重整阶段显著提升；且随着温度升高、S/C比(水蒸气与碳物质的量之比)增大，氢气产率与氢气体积分数呈现先增加后小幅减少的趋势；且相比于普通重整阶段，最高氢气产率所对应温度明显下降，在650℃，S/C比为4.5时氢气产率达到最大值87.60%，此时氢气体积分数为94.75%.

Experimental Study on Bio-oil Adsorption Enhanced Reforming by Using Double-effect Catalysts

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%.
