摘　　要：以玉米秸秆为原料,添加分子筛催化剂在体积为500 m L的高温高压反应釜中进行催化液化制备生物油实验研究。选取反应温度、催化剂含量和反应时间三个主要因素为变量,探究其对玉米秸秆催化液化产物分布的影响。利用气相色谱-质谱联用仪(GC-MS)和傅里叶红外光谱仪(FT-IR)对玉米秸秆生物油的成分和官能团结构进行分析。结果表明,玉米秸秆的最佳催化液化条件为,反应温度为340℃,玉米秸秆15 g,Fe HZSM-5催化剂含量为6.67%,反应时间为30 min。在此条件下,生物油产率为28.03%,催化液化整体转化率为81.73%。生物油的主要成分为酚类和长链酯类,生物油的热值达30.08 MJ/kg。The hydrothermal catalytic liquefaction of corn stalk（ CS） in a 500 m L batch reactor was conducted.The influence of reaction temperature and catalyst quantity as well as reaction time on the products distribution was investigated. The main components and functional groups of bio-oil with and without catalysts were characterized by gas chromatography / mass spectrometry（ GC-MS） and Fourier transform infrared spectrometry（ FT-IR）. The result shows that the optimal conditions of liquefaction are 15 g CS with 6. 67% Fe HZSM-5 at340 ℃ for 30 min,at which the bio-oil yield reaches a maximum of 28. 03% with the highest CS conversion of81. 73%. The main components of bio-oil are phenols and esters,and the HHV of the bio-oil reaches to30. 08 MJ / kg.
