Because of the limited supply

non-renewability

and environmental pollution of fossil energy sources

more and more attention has been focused on research high value-added chemicals and fuel from the degradation of lignin. ligin

usuallly used as fuel

has a complex polymer structure which make it difficult to be used as a chemical raw material. Worse yet

complex polymer structure is also an obstacle of research on lignin depolymerization. So

research on the mechanism of lignin pyrolysis by using lignin model compounds was developed rapidly. The research status of pyrolysis process of lignin model compounds were summarized in present paper. Different pyrolysis process characteristics

advantages

application and related mechanism of the lignin monomers

dimers and multimers were introduced

followed by the prediction of the future development of pyrolysis process of lignin model compounds.
