Abstract
An object of the present invention is to provide a method for producing a liquefied fuel oil using biomass as a feedstock, in which a relatively inexpensive liquefaction apparatus is used; a good balance is maintained between the liquefaction of water-insoluble lignin and the liquefaction of water-soluble cellulose to achieve a high yield of the liquefied fuel oil based on the biomass solids content; and the amount of ash derived from an alkali catalyst and the like is low. The method for producing a liquefied fuel oil using biomass as a feedstock is characterized by adding, to biomass comprising lignocellulose, a solvent comprising an organic solvent and having a moisture content adjusted to 10 to 25 wt %, including moisture contained in the biomass, and liquefying the biomass at a temperature of 250 to 350° C.
