Hydrothermally stable Ru/HZSM-5-catalyzed selective hydrogenolysis of lignin-derived substituted phenols to bio-arenes in water

In the context of arenes generated from bioresources, a hydrothermally stable catalyst Ru/HZSM-5 is reported for the quantitative conversion of lignin-derived phenol, anisole, guaiacols, and syringols into bioaromatic hydrocarbons in a one-pot aqueous-phase process in moderate conditions (240 °C, 2 bar H₂), with a high carbon balance of 98.6%.
