COMMINUTION AND DENSIFICATION OF BIOMASS PARTICLES

摘要

A method is disclosed for reducing the mechanical strength of solid bi?mass material, in particular ligno-cellulosic biomass The method comprises heating the solid biomass material Io a temperature in the range of 105 0C to 200 0C. The heat treatment, which is referred to as "toasting", significantly reduces the mechanical energy required for reducing the particle size of the solid biomass material. The method is particularly suitable as a pretreatmemt step to a conversion reaction of the solid biomass material
