PROBLEM TO BE SOLVED: To produce a solid fuel of a high energy density from a lignocellulosic material by decomposing hemicellulose using an acid hydrolysis method by a hydrothermal treatment.SOLUTION: A lignocellulosic material 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, while various kinds of oligosaccharides and monosaccharides are produced from a solution generated in the hydrothermal treatment and/or the dehydration/compression. |
