METHOD FOR PRETREATING BIOMASS, AND METHOD FOR PRODUCING BIOMASS FUEL
[Problem] To remove an alkali metal from a biomass with high efficiency to promote the effective utilization of the biomass as a biomass fuel. [Solution] A biomass containing an alkali metal and a chlorine content, such as an oil palm empty fruit bunch, is squeezed, and is then washed with water while applying a physical impact on the biomass. By squeezing the biomass to disrupt plant cells in the biomass and then washing the biomass with water while applying a physical impact on the biomass, it becomes possible to remove the alkali metal from the softened biomass with high efficiency. Subsequently, the biomass that has been washed with water is drained and is then washed by water spraying. This washing by water spraying enables the reduction of the amount of the alkali metal remaining in the biomass to 0.2% by mass or less. The biomass in which the content of the alkali metal has been reduced to 0.2% by mass or less is dried, crushed and then shaped to produce a good-quality biomass fuel having a reduced alkali metal content.
