Catalytic depolymerization of lignin for the production of value-added fuels and chemicals has received increasing attention among many researchers due to its potential as a sustainable alternative to petroleum-derived fuels. However, efficient depolymerization of lignin to valuable aromatic monomers is highly challenging due to its inherent recalcitrant structure. In addition, phenolic monomers formed during lignin depolymerization are highly reactive and easily undergo rapid repolymerization to oligomers or char, limiting the production of valuable aromatic monomers with a high yield. In this work, we have investigated a combination of supported metal (i.e., Ru/C) and base catalysts (i.e., MgO/ZrO2) for the effective depolymerization of kraft lignin into aromatic monomers. We will show how the synergy between metal and base sites can enhance the extent of lignin depolymerization and the corresponding monomer yield. |
