HHV prediction was applied to samples of 17 different lignins and data for 53 samples of several biomass resources obtained from literature. The HHVs calculated from this equation showed a mean difference of 0.49 % for different lignins and 2.13 % for biomass resources. Keywords Lignin, higher heating values, prediction 1.
