Abstract: Other than cellulose,lignin was the second largest biomass resource in nature.Due to the abundant aromatic units and active group (such as phenolic hydroxyl,etc.) in its' polymer structure,the depolymerization of lignin can partially substituted the fossil resources,which is beneficial to alleviate the energy crisis.At present,the overall utilization of lignin is still low.It was one of the important ways to achieve the high value and resource utilization of lignin by converting it into high value-added chemicals via chemical methods.The utilization of lignin through depolymerization was reviewed,the catalyst design was discussed.Moreover,the advantages of preparation of macromolecule materials by lignin were summarized.On the basis of characteristics of lignin conversion,a new process was proposed for the preparation of green binder by using small molecular compounds prepared from lignin sulfonate by depolymerization using hydrotalcite as catalyst via hydrolysis method.The development direction of depolymerization-conversion utilization technology was forecasted,which would provide a theoretical basis for the high value and the utilization of lignin resources.
