水曲柳热解的研究用热重分析仪和傅里叶变换红外光谱仪联用，研究了4种沸石分子筛催化剂对锯末的催化作用。纯满洲灰分和三种主要成分的热解。以纤维素、木聚糖、木质素为参照物。本研究所考察的四种沸石催化剂(即B、B、C、C、C)。HZSM-5、H-β、USY和Na-Y)均能催化脱水反应，抑制挥发分的释放，明显提高最终残渣产率。Y型催化剂表现出最明显的催化作用，如抑制醛、酸和醚的生成，促进异构烷烃和芳烃的生成。优选的催化剂应同时具有高的脱氧活性和产烃的选择性。
Pyrolysis of Manchurian ash (Fraxinus mandshurica Rupr.) sawdust with four zeolite molecular sieve catalysts was performed on a thermogravimetric analyzer coupled with a Fourier transform infrared spectrometer. Pyrolysis of pure Manchurian ash and three main components, viz. cellulose, xylan, lignin, was also carried out as reference. The four zeolite catalysts investigated in this study (viz. HZSM-5, H-β, USY and Na-Y) all catalyze the dehydration reaction, restrain the release of volatiles, and obviously promote the final residue yields. Y-type catalysts show the most evident catalytic effect, such as restraining the formation of aldehydes, acids, and ethers, and promoting that of isoalkanes and aromatics. The preferred catalyst should have both high activity for deoxygenating and selectivity for hydrocarbon production.
