Lignocellulosic biomass is an abundant renewable resource and most importantly has enormous potential to be converted into various value-added chemicals for future biorefinery application. However, selective conversion of woody biomass is extremely challenging due to its complex structure. Herein, we investigated bimetallic Cu-Ru/HZSM5 catalyst for one-pot lignocellulose conversion in aqueous environment. HZSM5 provides acid sites required for consecutive depolymerization of holocellulose, dehydration, and isomerization while Cu-Ru synergistically promote hydro-genation/genolysis. Direct conversion of lignocellulose yielded up to 24.2wt% of lignin-derived monomers, cyclopentanone and methyl-cyclopentanone at 300oC under pressurized H2 (3MPa) for 1h. This one-pot process can be a very promising and energy-efficient approach for utilization of whole lignocellulose into versatile platform chemicals in pharmaceuticals, fragrance, and polymer industries. |
