对玉米秆酶解残渣木质素进行热重分析，结果表明，木质素热裂解主要发生在180-500℃，综合考虑热解效率和液体产物产率最大化，选取快速热解实验的热解温度范围为500-600℃。并在实验室自行设计的装置上对木质素进行热解实验，在550℃时得到热解液体产物热解油最大产率，为30．9％。对热解油进行气相色谱一质谱分析，结果显示木质素热解产物相对简单，一级和二、三、四级热解油的成分主要是酮类和酚类；而电捕油中酮类很少，大部分是酚类，另有15．07％的2,3．二氢苯并呋喃。%Thermogravimetric analysis (TGA) of enzymatic hydrolysis lignin from the cornstalks residue was investigated, it showed that lignin cracked mainly at 180-500℃, considering the pyrolysis efficiency and the maximum yield of liquid products, the range of 500-600℃ was selected as the fast pyrolysis experiments temperature. Then the pyrolysis experiments of lignin were undertaken and the maximum yield of liquid products, 30.9%, was obtained at 550~C. The gas chromatography-mass spectroscopy (GC-MS) analysis showed that the products of lignin pyrolysis oil were relatively simple, the main composition of pyrolysis oil collected by condensers were ketones and phenols, while the vast majority of the electrostatic oil was phenols, together with 15.07% of 2,3-dihydrobenzofuran, but ketones were rare in the electrostatic oil.
