PROBLEM TO BE SOLVED: To achieve the effective use of a hemicellulose decomposed product by decomposing hemicellulose using an acid hydrolysis method by a hydrothermal treatment, when producing a solid fuel with a high energy density by removing the hemicellulose from a lignocellulosic material.SOLUTION: There is provided a method for producing a solid fuel from a lignocellulosic material which is subjected to a hydrothermal treatment, dehydration, compression and drying. Preferably, a liquid ratio is 0.5-8.0 in the hydrothermal treatment. Furfural is produced from a gas generated in the hydrothermal treatment and/or the dehydration/compression. Furthermore, preferably, at least one or more compound among various oligosaccharides and monosaccharides is produced from a solution generated in the hydrothermal treatment and/or the dehydration/compression. |
