英文摘要	Pyrolytic lignin obtained by separation of the fast pyrolysis bio-oil of biomass is problematic for use as a fuel and chemical. A catalytic cracking process for pyrolytic lignin was therefore explored using pristine catalysts (MoO3, HZSM-5, and a alpha-Al2O3). The results demonstrated that pyrolytic lignin can be converted into aromatic hydrocarbons and phenols in a one-pot process. Among the three catalysts, MoO3 was more efficient for aromatic hydrocarbons and phenols, with yields of up to 9.2 and 7.9 wt%, respectively, under the conditions of 340 degrees C and an H-2 atmosphere. Catalyst dosage, reaction temperature, and H-2 pressure were investigated in detail, and it was found that the aromatic hydrocarbon yield was highly catalyst dosage dependent. The regeneration of used catalyst was also explored, and the catalytic activity of regenerated MoO3 catalyst was recovered by calcination in the presence of O-2. This work provides a potential alternative for the production of aromatic hydrocarbons and phenols from pyrolytic lignin.
