METHOD FOR SACCHARIFICATION OF BIOMASS |
| 摘要 |
A method for saccharification of lignocellulosic biomass, the method comprising (1) a pretreatment step of impregnating lignocellulosic biomass with an aqueous alkali solution, subjecting the resultant mixture to solid-liquid separation to remove part of the aqueous alkali solution, and then performing heat treatment, and (2) a saccharification step of enzymatically degrading the lignocellulosic biomass resulting from the pretreatment step to obtain a saccharified liquid can be applied to high-lignin lignocellulosic biomass, reduce the usage of alkali and water in the pretreatment step, increase the sugar yield in the saccharification step, decrease the reaction time, reduce enzyme adsorption on a biomass residue, and improve the enzyme recovery rate. |
