以碳酸钠为催化剂，在280~420℃的反应温度范围内，用水在高压釜中液化木质生物质。实验结果表明，工艺条件对主要液化产物(重油)的产率有显著影响。反应温度为380℃时，重油收率最高，并对不同反应温度下得到的重油进行了傅立叶变换红外光谱(FTIR)和气相色谱/质谱仪(GC/MS)分析。分析结果表明，该稠油是含有烃、醛、酮、苯酚和酯的复杂化合物。
Woody biomass was liquefied by water in an autoclave in the reaction temperature range of 280–420°C with sodium carbonate as the catalyst. The experimental results show that the yield of the main liquefaction product (heavy oil) was significantly influenced by the process conditions. The maximum yield of heavy oil was obtained at reaction temperature 380°C. The heavy oils obtained at different reaction temperature were analyzed by Fourier transform infrared spectroscopy (FTIR) and gas chromatography/mass spectrometry (GC/MS). The analytical results show the heavy oil is complex compound that contain hydrocarbon, aldehyde, ketone, hydroxybenzene and ester.
