Abstract New technology is needed to exploit the potential of lignin as a renewable feedstock for fuels, chemicals and performance products. Fast fluidized bed pyrolysis of different lignins at 400°C yields up to 21 wt% (d.b.) of a phenolic fraction containing 10 wt% (d.b.) of several phenols. Subsequent catalytic hydrotreating of this phenolic fraction with 100 bar of hydrogen in dodecane at 350°C yields mainly cycloalkanes, cyclohexanols and alkanes. For the production of monomeric phenols, it appears that the used ruthenium on carbon is a too active catalyst. However, cyclohexanols may be interesting products, e.g., for use as oxygenates in engine fuel. © 2009 American Institute of Chemical Engineers Environ Prog, 2009
