Selective Production of Bicyclic Alkanes for Sustainable Aviation Fuel by Catalytic Hydrodeoxygenation of Lignin‐Derived Bisphenols

Catalytic conversion of lignin to cyclic alkanes offers a promising route toward sustainable aviation fuel production. In contrast to the prevalent hydrodeoxygenation (HDO) of lignin oils for C6-C9 arenes and alkanes, here, we report an orthogonal approach for selective production of bicyclic alkanes (mostly C14 and C15 alkanes) from bisphenols isolated from arylated lignin oil. HDO of phenolic hydroxyl and methoxy groups in lignin bisphenols is promoted by heteropoly acid-metal catalyst synergy, favoring selective CO bond cleavage with minimal CC bond cleavage under moderate conditions.
