An analytical method was created in the research of biomass flash pyrolysis by pyrolysis gas chromatography, which can meet the need of studying on the kinetics and mechanism of biomass flash pyrolysis without the costly analytical apparatus. The results of material balance show that the analytical method is feasible. The experimental results from poplar sawdust and rice straw flash pyrolysis reveal that the product yield distribution is influenced greatly by the type of biomass, pyrolysis temperature and heating rate. The maximum liquid yields for poplar sawdust and rice straw were 77% in weight (68% organic matter and 9% water) and 65% in weight (50% organic matter and 15% water) respectively under the same operation condition: pyrolysis temperature 450°C, heating rate 500 °C/s and vapor residence time 0.9 s.
