Abstract
A method of preparing cellulosic biomass material for subsequent processing first comprises moving at least one stream of biomass material along a flow path. Then, the stream of cellulosic biomass material can be explosively dried and pulverized to disrupt lignocellulosic bonds, and to reduce a moisture content and a particle size of the cellulosic biomass material. Then, the stream of cellulosic biomass material can be electrically degraded the stream of cellulosic biomass material to disrupt lignocellulosic bonds. Additional pre-treatment and post-treatment processes can also be included.
