Abstract: Xylan, poly (¦Â-D-xylopyranose [1¡ú4]) extracted from the beechwood, was selected as the model compound of hemicellulose to investigate its thermal behavior over zeolites by using the thermogravimetric analyzer coupled with Fourier transform infrared spectrometer (TG-FTIR), and an analytical pyrolyzer coupled with gas chromatography and mass spectrometer (Py-GC/MS). The chemical structure of xylan and characterization of catalysts were first studied. All the three catalysts, HZSM-5, H-¦Â and USY, had obvious influence on deoxygenation and fragmentation reactions during xylan pyrolysis. The dehydration in the initial stage was enhanced and the char formation was suppressed. USY had the best effect on dehydration with the consumption of oxygenated compounds, such as acids and furans. The presence of HZSM-5 and H-¦Â catalyzed the formation of water, CO2 and alkanes, with the degradation of char residues.
