Abstract: Poplar wood (a typical hardwood) and pine wood (a typical softwood) were pyrolyzed using the pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) technique. The difference of components during fast pyrolysis reaction was investigated. The results indicated that due to the lignin composition difference of these two woods, the pyrolytic products from the pine wood did not contain syringol-type phenolics. Since the hemicellulose in poplar has more acetylated formation than the hemicellulose in pine. The GC contents of the acid products from the poplar wood reached 11.22%, compared with only 4.28% of the acid products from the pine wood. Moreover, the ash in these two woods had no great effects on the furans and phenolic products, but it would inhibit the formation of the anhydrosugars remarkably. After the demineralization pretreatment, the GC contents of the anhydrosugars from the poplar and pine woods increased by 86.4% and 52.4%, respectively.
