Abstract: Pinus massoniana, a fast-growing wood species that is plentiful in China, could be converted into high-quality bio-fuel through thermal-chemical conversion technology. The objective of this study was to obtain useful data for effective design and operation of biomass pyrolysis technology fed by P. massoniana. In this study a fixed bed reactor was used to determine the influence of temperature (400, 500, 600, and 700 ℃) on yields and properties of slow pyrolysis products for P. massoniana. The components of bio-gas were analyzed by gas chromatograph (GC), the properties of bio-char were analyzed by the Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) methods, and the components of bio-oil were analyzed by gas chromatograph/mass spectrometry (GC/MS). Results showed that as the pyrolysis temperature increased, the yield of bio-gas increased from 40.00% to 46.50%; whereas, the yields of bio-char and bio-oil decreased from 26.50% to 24.00% and 33.50% to 29.50%, respectively. At 700 ℃, the lower heating value (LHV) of bio-gas reached its maximum value of 12.11 MJN-1m-3 with components of CO2(24.00%), CO(25.00%), CH4(15.50%), H2(25.50%), and CnHm (2 n4)(0.97%); also the maximum values for LHV (31.8 MJkg-1) and specific surface area (536.13 m2g-1) were attained. The main components in the bio-oil were acetic acid (5.30%), 1-hydroxy-2-butanone (4.10%), hydroxy-acetone (8.50%), phenol (2.70%), and methylphenol (3.90%) which could be important chemicals source by refining .[Ch, 3 fig. 3 tab. 18 ref.]
