Analysis of Influence Factors on Wooden Biomass-pyrolysis Liquefaction

Woody biomass energy is an important part of the renewable energies;the fast pyrolysis technologies are the hotspot of studies on woody biomass energy both at home and abroad.Based on the summary of fast pyrolysis technologies of woody biomass,this paper focued on the temperature,heating rate,pressure,residence time of gas phrase,characteristics of wooden biomass,catalyst,and pyrolysis reactors in the process of pyrolysis.The paper also illustrated the factors of fast pyrolysis technique on yield of bio-oil.
