Techno-Economic Assessment of Two Process Routes for Lignin-Derived Alkylphenols and Aromatic Hydrocarbons.

ABSTRACT: Lignin valorization processes are crucial for enhancing the economic feasibility of lignocellulosic biorefineries and improving waste management in the pulp and paper industries. This study performed a detailed techno-economic evaluation comparing two alternative lignin conversion pathways, focusing on the production of aromatics and alkylphenol: HydroDeOxygenation (HDO) and HydroDeOxygenation are preceded by HydroThermal Liquefaction (HDO + HTL). The analysis revealed that the integrated HDO + HTL is technically and economically superior, since it provides higher alkylphenol yield (30-35% by weight) and requires significantly less hydrogen, consuming only 22-28 kg of H₂ per ton of lignin. As a direct consequence of the superior yield and lower reagent consumption, the minimum s
