Abstract
A solidified biomass consisting of semi-carbonized or pre-semi-carbonized solid matter is pressure-formed from raw biomass material while being heated and has a maximum compressive strength of 60-200 MPa and calorific value of 18-23 MJ/kg. A method for producing the solidified biomass: includes crushing raw biomass material; loading a barrel with the crushed raw biomass material; inserting a pressure applying piston into a hollow of the barrel; pressure-forming the crushed raw biomass materials by applying pressure with the pressure applying piston while heating the material; obtaining semi-carbonized or pre-semi-carbonized solid matter by retaining constant time of the heating and the pressurizing; cooling the semi-carbonized or pre-semi-carbonized solid matter while maintaining pressure to obtain a cooled solid; and taking out and drying the cooled solid, wherein the pressure applying piston and the hollow of the barrel have very small clearance between their outer and inner peripheries.
