摘要

为了消除生物质热解产生的焦油，本研究制备了一种镍基整体式催化剂。表征了比表面积、孔隙体积。考察了不同酸处理时间、不同载镍量对其催化活性的影响。结果表明，酸处理5h后的比表面积为156m2/g。有效组分的加载量与涂层次数成线性关系。涂层次数对气体成分的影响很小，H2和CO的含量总和保持在90 vol %以上。催化反应6h后，催化剂的相结构没有发生变化，焦油转化率由87.4%下降到81.3wt %。焦化量经测试约为1wt %。

Nickel-based monolithic catalyst for tar cracking of biomass pyrolysis

To eliminate the tar coming from biomass pyrolysis, a kind of nickel-based monolithic catalyst is prepared in this study. The specific surface area, pore volume is characterized. The effect of different acid treatment time, different nickel loading quantity on its catalytic activity is investigated. The results show that the specific surface area is 156m2/g after acid treatment of 5h. The loading quantity of active component is linear with coating times. The influence of coating times on the gas composition is quite small, and the sum of the content of H2 and CO keeps as high as 90 vol %. After 6h catalytic reaction, the phase structure of catalyst hasn't any change, and the tar conversion decreased from 87.4 wt % to 81.3wt %. The quantity of the coking is tested to be about 1wt %.
