SOLID BIOFUEL FROM TWO-STAGE SEMI-CARBONIZATION STEP, AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2023/100814

A1

As a solid biofuel serving as an alternative or mix-in for coal coke, there is demand for a solid biofuel that has a high combustion ratio and is capable of long-term combustion and of maintaining form during combustion.　This solid biofuel is obtained using a manufacturing method including: a first-stage step in which a raw material that has been chipped from a biomass resulting from photosynthesis is subjected to semi-carbonization to obtain a semi-carbonized raw material in which some of the moisture and volatile content of said raw material is released; and a second-stage step in which the semi-carbonized raw material is heated and pressed to obtain a consolidated molded article. Said solid biofuel has a fuel ratio exceeding 0.4 and a density of 1.0 g/cm3 or greater, and can be used as a coal coke alternative and contribute to CO2 reduction.
