以小麦秸杆为原料，利用自制的固定床式热解反应器，在400℃、450℃、500℃和550℃四种热解温度下进行了热解液化试验。采用气质联用仪定性方法测定了四种热裂解温度下制取生物油主要化学组分，利用电子扫描电镜对小麦秸秆和残炭进行了形态表征。结果表明：不同裂解温度制得的生物油成分大致相同，主要由醛类、酮类、苯酚类、醇类和有机酸类化合物组成。热裂解温度对生物油的主要化合物相对含量有一定的影响，但不显著。随着热解温度升高，乙酸相对含量减少，而糠醛和大多数酚类化合物相对含量增加；残炭表面产生的裂缝越大，结构更加松散，且有热解碳粒子沉淀其中。

Biomass fast pyrolysis was carried out on a self-manufactured fixed bed reactor with w heat straw at 400℃ ,450℃ ,500℃ and 550℃ .In order to determine the main chemical compo‐nents of bio-oil and compare the influence of different temperatures on the components ,GC-MS for qualitative analysis method was adopted ,and the surface morphology of raw material and char were characterized by SEM .Results showed that there were no significant differences among the four bio-oil components .But pyrolysis temperatures exerted certain impact on the relative con‐tents of main compounds .With pyrolysis temperature increasing ,contents of furfural and most of the phenolic compounds increased ,except acetic acid ,and the char surface cracks become lar‐ger .Some pyrolytic carbon particles embeded in the structure were observed at higher tempera‐ture .
