Description

technical field

[0001] The invention belongs to the field of bioenergy, and specifically relates to a method for separating lignocellulosic raw materials through improved formic acid pretreatment of lignocellulosic biomass, thereby efficiently obtaining high-purity and easy-to-use cellulose, lignin and hemifibers Methods. Background technique

[0002] Traditional fossil energy sources (coal, oil, natural gas, etc.) are increasingly depleted, environmental problems caused by greenhouse gases are becoming more and more serious, and the demand for transportation fuels that are most dependent on fossil energy is increasing year by year, so renewable agricultural and forestry biomass fiber raw materials (such as wood, corn stalks, rice straw, wheat straw, bagasse, etc.) into liquid fuels or materials and chemicals that replace fossil resource sources are of great significance and have become a research hotspot in various countries.

[0003] Lignocellulosic raw materials are the ...
