The effect of temperature, time, hydrogen pressure and amount of catalyst on production distribution and the bio-oil yield obtained from the direct liquefaction of sawdust in the petroleum ether (60-90°C) are investigated. The highest sawdust conversion obtained was 72.32% with a bio-oil yield of 47.69% were obtained at 370°C, 40min and 5wt.% catalyst content with the initial H2 pressure of 3.0MPa. Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) approach was utilized to analyze the non-volatile fraction. In this study, the composition of bio-oil could be analyzed in an unprecedented detail through a combination of GC-MS and FT-ICR MS techniques.
考察了温度、时间、氢气压力和催化剂用量对木屑在石油醚（60-90°C）中直接液化产物分布和生物油收率的影响。在初始氢气压力为 3.0MPa 时，在 370°C、40min 和 5wt.%催化剂含量下，获得了最高的木屑转化率 72.32%和生物油收率 47.69%。采用傅里叶变换离子回旋共振质谱（FTICR-MS）方法分析了非挥发性组分。在这项研究中，通过 GC-MS 和 FT-ICR MS 技术的结合，可以以前所未有的细节分析生物油的组成。
