With the model of biomass moving-bed pyrolytic polygeneration system based on Aspen Plus simulator, the products characteristics of bio-char, bio-oil and pyrolysis-gas were studied and the influence of pyrolysis temperature on the system consumption of fuel, cooling water, and electricity were investigated. Results showed that the heating value of bio-char rises as the pyrolysis temperature increases. The maximum products yields of bio-oil and syngas were obtained at 450oC and 650oC, respectively. When the pyrolysis temperature was 450oC, the heavy bio-oil mainly consists of sugar derived and fatty acid, while the major components of light bio-oil were aldehyde, alcohol and moisture. CO and CO2 were the main components in the syngas at 650oC. In addition, the consumption of fuel and electricity rises with the temperature increase, while the consumption of cooling water decreases firstly and then increases at 450oC.
