Abstract
In this study the effects of particle size and water content on the yields and physical/chemical properties of pyrolytic products were investigated through fast-pyrolysis of yellow poplar. Water content was critical parameters influencing the properties of bio-oil. The yields of bio-oil were increased with decreasing water content. However, the yield of pyrolytic product was not clearly influenced by feedstock's particle size. The water content, pH and HHV (Higher Heating Value) of bio-oil were measured to 20~30%, 2.2~2.4 and 16.6~18.5MJ/kg, respectively. The water content of feedstock was clearly influenced to water content of bio-oil. In terms of bio-char, HHV of them were measured to 26.2~30.1 MJ/kg with high content of carbon over 80%.
