ABSTRACT

Abstract The unique chemical composition of biomass lignin makes it a versatile biogenic polymer that offers a variety of attractive features as a starting material for the production of aromatic chemicals. However, the ability to transform the heterogeneous structure into a useful single molecule with a high yield remains challenging. The conventional depolymerization reaction of this matrix lignin via hydrogenolysis yields a family of phenolic structures, including guaiacol, phenol, anisole, cresol, catechol, vanillin, resorcinols, and quinones. All are identified as valuable chemicals and are difficult to obtain from other sources such as petroleum-derived chemicals. This chapter comprehensively reviews the derivation of lignin from biomass resources and advances in the conversion of phenolic derivatives (monomeric compounds) to bulk aromatic chemicals (e.g., benzene, toluene, phenol) and fungible liquid transportation fuel blends (e.g., cyclohexane, cyclohexanol, and cyclohexanone), preferably via heterogeneous catalytic reactions.
