PURPOSE:To pretreat continuously a biomass for liquid fuel or chemical raw material in a short time, by feeding the biomass to a twin-screw extruder, adding an aqueous solution of an alkali compound to the extruder during feeding. CONSTITUTION:A biomass (e.g., bagasse, Japanese beech, silver fir, oil paper, etc.) having preferably <=30mm. average particle diameter is fed to a twin-screw extruder, an aqueous solution of an alkali compound such as NaOH, Na2S, etc. is added to the extruder, the biomass is blended with the aqueous solution preferably at 60-230 deg.C, kneaded and reacted.
