Abstract

Using our self-designed facility for lignocellulosic biomass hydrolysis under extremely low acid, and under the optimal reaction conditions of hemicellulose and cellulose determined by xylan and quantitative filter paper as the model, two-step dilute acid hydrolysis was carried out in detail on pine, fast-growing poplar and maize straw. The corresponding conversion ratio is 41.78%, 57.84% and 53.44% and the total reducing sugar conversion ratio is 39.28%, 42.83% and 23.82% respectively. Simultaneously, sugar component analysis of the products was performed by high performance liquid chromatography (HPLC) and monosaccharide and oligosaccharide content were compared. Finally, poplar hydrolysis residues were analyzed by proximate and ultimate analysis.
