Abstract:With the increasing depletion of petrochemical resources and the environmental pollutioncaused by their consumption, the development and utilization of renewable resources have attracted ex⁃tensive attention. Agroforestry biomass (ABS) is a low-cost, easily available and widely distributed re⁃newable resource, which is mainly composed of cellulose, hemicellulose and lignin, and is a potentialrenewable energy resource. Pyrolysis of lignocellulosic biomass to phenol-enriched bio-oil is a promis⁃ing application in the future. The pyrolysis methods, composition of lignocellulosic biomass, pyrolysismechanism of main constituents of lignocellulosic biomass (cellulose, hemicellulose, lignin), and theeffects of pyrolysis methods and catalyst type (active biochar, metal oxides, zeolite) on the phenolsyield in the obtained bio-oil were discussed in detail. At last, the future research orientation of ligno⁃cellulosic biomass pyrolysis into phenol-enriched bio-oil was put forward based on some key questionsto be solved. The formation of phenolics bio-oil via lignocellulosic biomass pyrolysis will provide a newpath for the replacement of fossil energy, and provide theoretical support for the national " carbon pea⁃king, carbon neutrality" goals.
