In order to utilize lignin residue from the pretreatment of empty fruit bunch (EFB) and crude glycerol from biodiesel production, lignin residue was solvothermally liquefied using crude glycerol to produce lignol. The optimal liquefaction conditions for lignol production were determined to be 10% biomass loading, 5% acid loading, a liquefaction temperature of 170 8C, and a liquefaction time of 120 min. The biomass conversion at the optimal conditions was 47.9%. The lignols possess hydroxyl number of 1649.3 mg KOH/g and acid number of 8.4 mg KOH/g. Fourier transform infrared spectroscopy revealed that the lignol was suitable for biopolyurethane synthesis.
