Abstract :
As the most abundant renewable forestry resource in South China, Eucalyptus urograndis wood is most suitable for bioenergy. Therefore, Py-GC/MS was used to analyze the components from pyrolysis products of Eucalyptus urograndis wood. After treated with freeze-drying, the comminuted power of Eucalyptus urograndis wood was pyrolyzed in He atmosphere at 590square, then the pyrolysis product was analyzed by online linked GC/MS. Relative content of each component was determined by area normalization, and 38 compounds representing 99.35% were identified. The main and abundant constituents were carbon dioxide (59.93%), ethene, ethoxy- (18.73%), 1,6-anhydro-.beta.-D-glucopyranose (4.58%), phenol, 2-methoxy-4-(l-propenyl)- (4.19%), cedrol (3.14%), thylene oxide (2.33%), glycidol (1.23%), 1H-3a,7-methanoazulene, 2,3,4,7,8,8a-hexahydro-3,6,8,8-tetramethyl- (1.16%), butanal (1.13%), ethanone, 1-phenyl-, oxime (0.59%), and so on. So pyrolysis products of Eucalyptus urograndis wood could be used to bioenergy, bio-pesticides, expensive chemicals, and so on.
