A Review on Catalytic Depolymerization of Lignin towards High-Value Chemicals: Solvent and Catalyst

Lignin is a type of natural aromatic material with potential application prospects obtained from lignocellulosic biomass. Recently, the valorization lignin has received increasing attention both industry and academia. However, there still challenge in efficient due to complexity stability structure. Recent work been focused on catalytic depolymerization explore promising way valorize into chemicals high value biofuels. Considerable research catalysts, solvents, reaction parameters during process, which significantly affects product distribution productivity. Thus, catalysts solvents have significant influence effect. This review article assesses current status hydrogenolysis lignin, mainly focusing reaction. First, various applied reactions are extensively overviewed. Second, recent progress metal as well their supports summarized. Furthermore, discussion challenges this area included.
