Catalytic microwave pyrolysis of biomass using activated carbon (AC) was investigated to determine the effects of pyrolytic conditions on the yields of phenol and phenolics. The bio-oils with high concentrations of phenol (38.9%) and phenols (including phenol and alkyl substituted phenol) (66.9%) were obtained. The increase of phenols and decrease of guaiacols compared to pyrolysis without AC addition had a close relationship with the decomposition of lignin under the performance of activated carbon. The high content of phenol and phenolics obtained in this study can be used either as partial substituent of transportation fuel after hydroprocessing or as feedstock for organic synthesis and chemical industry after purification.
