Patent number: 8747495Abstract: 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.Type: GrantFiled: June 1, 2012Date of Patent: June 10, 2014Assignees: Kinki University, Naniwa Roki Co., Ltd.Inventors: Tamio Ida, Akio Nakanishi
