Abstract

Organosolv lignin extracted from the four representative lignocellulose feeds of oil palm empty fruit bunch (agricultural waste), oak (hardwood), pine (softwood) and Miscanthus giganteus (grass) is depolymerized using Ru/H-zeolite β to produce phenolic hydrocarbons. The bulky methoxy functionality, which is rich in oak and pine, sterically hindered the ether bonds, decreasing the yields of phenolic monomers and improving the β–β coupling to repolymerize lignin fragments. Both depolymerization and repolymerization are improved at a higher reaction temperature. The structures and the reaction behavior of organosolv lignin are observed using NMR, GPC, N₂-physisorption, SEM and DLS analysis methods.
