The catalytic hydrogenolysis of softwood lignins is normally conducted at temperatures below 200 °C but tends to provide monomer yields of less than 30 mol% as a consequence of the non-cleavable 4-O-5 and condensed (C–C) linkages of phenylpropane units in lignin.In the present study, catalytic hydrogenolysis at higher temperatures …
