摘要：
Brewer's spent grain was applied as a low-cost industrial type of lignocellulose biomass in a liquefaction process with crude glycerol. Influence of the reaction time and solvent: biomass ratio on the efficiency of the process, chemical structure and basic properties of obtained biopolyols was analyzed. Spectroscopic studies of the prepared polyols and solid residues shed light on the biomass degradation mechanism through application of microwaves and further reaction of degradation products with solvent particles.
