1. A method for hydrolytic pre-treatment of lignocellulosic and perennial herbaceous biomass, comprising:
- preparing lignocellulosic biomass or perennial herbaceous biomass in form of chips, said lignocellulosic biomass comprising pine wood and oak wood, said perennial herbaceous biomass comprising reeds and flame grasses;
immersing the biomass in water or triturating the biomass in a wetting manner;
microwaving the hydrated biomass or the wet-triturated biomass for 10 to 40 min at 500 W to 800 W;
dewatering the microwaved biomass; and
popping the dewatered biomass under a pressure of 5˜
30 kgf/cm2 in a popping machine.

Abstract
Disclosed is a method for the hydrolytic pre-treatment of lignocellulosic and perennial herbaceous biomass. By the method, a material suitable for use in the production of saccharides and biofuels can be prepared from lignocellulosic biomass such as pine wood and oak tree wood and perennial herbaceous biomass such as flame grasses and reeds. It is characterized by wet-triturating, microwaving and popping processes. Also, a method is provided for the production of saccharides and bioethanol from the pre-treated biomass.
