Abstract
An explosive operation for the effective utilization of biomass was studied experimentally with Larix leptolepis under various operating conditions of steam pressure from 1.08 to 4.81 MPa and reaction time from 1 to 20 min. Size distribution of exploded wood was described by the Rosin-Rammler equation. The products were separated into hemicellulose, cellulose, methanol-soluble lignin and Klason lignin. The effects of operating conditions on the characteristics of exploded wood were studied from the experimental data of shape and size of exploded wood, amounts of extractive components and enzymatic hydrolysis rate. The equation for saccharification of exploded wood is expressed as a function of steam pressure, reaction time and enzymatic hydrolysis time.
