Pretreatment method of wood biomass by sequential Fenton oxidation and hydrothermal treatment

摘要

The present invention relates to a pretreatment method for a woody biomass which removes hemicellulose from a woody biomass raw material and decomposes lignin to increase the yield of destroying the crystalline structure of cellulose. The pretreatment method of the woody biomass according to the present invention The effect of removing hemicellulose from the woody biomass raw material by sequential Fenton oxidation treatment and hydrothermal treatment and breaking the crystalline structure of the cellulose by lignin decomposition is remarkably improved, It is possible to obtain xylose or glucose from woody biomass in high yield. Compared with the conventional method using the wood-based biomass pretreatment method and the chemical treatment (acid or alkali treatment) after the Fenton oxidation treatment, the hydrothermal treatment is performed instead of the chemical treatment, thereby saving costs and being environmentally friendly .;
