在管式炉中对木屑进行烘焙，对其产物进行热解和催化热解研究。考察了不同温度下烘焙挥发物析出特性以及烘焙预处理对生物质热解的影响，重点比较了烘焙后乙酸、愈创木酚类和芳烃催化热解产率的变化规律。结果表明，烘焙温度为250,℃时，在HZSM-5催化剂作用下能有效改善热解产物的选择性，甲苯和二甲苯产率达到未烘焙生物质的近2倍，而乙酸和大部分愈创木酚类产物的产率较原生物质催化热解产率有明显降低。

Sawdust pretreatment of torrefaction followed by the pyrolysis or catalytic pyrolysis of its productwas conducted in a tube furnace. The effects of torrefaction temperature on vapor distributions and product distributions of pyrolysis were studied. The yields of acetic acid,guaiacols and aromatics before and after torrefaction were com-pared. The results show that the selectivity of pyrolysis products can be effectively improved when the torrefaction temperature is 250,℃ with HZSM-5 catalyst. The yields of toluene and xylene are nearly twice that with original biomass,while the yields of acetic acid and guaiacols decrease obviouslycompared with that with original biomass in catalytic pyrolysis process.
