    Abstract: A biomass pretreatment method is provided to improve the bio-digestibility of lignocellulosic biomass. This pretreatment method densifies biomass with alkaline or acidic chemical(s) to obtain densified biomass containing chemicals. Pretreatment effects are realized during densification. The chemicals in densified biomass further react with biomass during biomass storage and transportation to improve the pretreatment effects. Further treatment (e.g. stream) can also be applied to the densified biomass to achieve better effects. As chemicals are mixed well with biomass during densification and the biomass density is greatly increased, further treatment is of high efficiency and high solid loading. This pretreatment method is simple and the densified biomass with chemicals is resistant to microbial contamination/degradation and thus facilitates storage and transportation.
