摘要 |
A solidified biomass consisting of semi-carbonized or pre-semi-carbonized solid matter is pressure-formed from raw biomass material while being heated under a substantially sealed-up condition to allow hemicellulose among the main components of the raw biomass material, i.e. lignin, cellulose and hemicellulose, to be thermally decomposed and to allow a low-temperature reaction to occur between the cellulose and lignin while maintaining their skeletons. The pre-semi-carbonized solid matter or semi-carbonized solid matter has a maximum compressive strength of 60-200 MPa and calorific value of 18-23 MJ/kg.
