摘要： The present disclosure relates to a physically pretreated biomass composition capable of membrane filtration treatment in a biomass solid-liquid separation process, and a method for preparing sugar therefrom.
The physically pretreated biomass composition is very useful for the biomass treatment process because MF clogging phenomena do not occur through specific physical pretreatment (attrition milling) of herbaceous biomass and because MF passage speed is improved such that MF can be used in the biomass solid-liquid separation process.

摘要： The present disclosure relates to a physically pretreated biomass composition, which enables chemical treatment in a biomass composition comprising a high concentration of a biomass substrate, and a preparation method thereof.
Through specific physical pretreatment (attrition milling) of herbaceous biomass, the physically pretreated biomass composition has fluidity/flowability at a substrate concentration of biomass of 20% (w/w) (biomass:solvent = 1:4) or above, and thus the pretreatment cost may be reduced, and it is very useful in biomass treatment processes.
