摘  要：
利用热解-气质联用仪对杉木进行了分级催化热解实验,考察温度和催化剂对热解产物组成和含量的影响。结果表明第1级300℃热解产物种类较少,以有机抽提物为主,而第2级500℃热解产物种类较多。ZSM-5和MCM-41两种催化剂都降低了热解产物中羰基化合物和大分子木质素热解产物的质量分数。ZSM-5降低了热解产物乙酸的质量分数,并形成大量芳香烃;而MCM-41提高了热解产物中乙酸和糠醛的质量分数。

摘  要：
tep-wise pyrolysis of fir was conducted in the presence of catalysts by using pyrolysis-gas chromatography/mass spectrometry(Py-GC/MS).The effects of catalysts and temperature on composition and content of the pyrolysis products were studied.The results showed that few types of the products were found in the first-step 300℃ pyrolysis and the main products were extractives,while a great variety of products were detected in the secondstep 500℃ pyrolysis.ZSM-5 and MCM-41 could reduce the contents of carbonyls and macromolecular lignin derivatives.ZSM-5 catalyst was helpful to reduce the content of acetic acid,and produced lots of aromatic hydrocarbons in the pyrolysis products.The content of acetic acid and furfural in the prolysis products were obviously increased by the presence of MCM-41 catalyst.
