Abstract

To evaluate the bio-solid energy of raw materials, nineteen softwood species and twenty-seven hardwood species were used for chemical composition, elementary analysis and energy content calculation. Variations in organic solvent soluble extractives were high in both softwood and hardwood species. Lignin content in softwood species (25.6-36.0%, 19 species average 30.0%) was higher than hardwood species (16.5-28.4%, 27 species average 21.7%) but polysaccharide content in hardwood species (59.6-81.6%, 27 species average 69.0%) was higher than softwood species (56.4-65.1%, 19 species average 61.2%). More carbon content in softwood species than hardwood species came from higher lignin content in those softwood species, especially Norway spruce (50.0% carbon content). In calorimetric value estimation, softwood species (average 18.5 MJ/kg) was higher than hardwood species (average 15.63 MJ/kg) due to higher lignin content and less carbohydrate content.
