NOVELTY - A lignocelluloses raw material degrading method involves crushing lignocellulose raw material with cationic surfactant hexadecyl trimethyl ammonium bromide followed by subjecting to solid-liquid separation. An auxiliary non-ionic surfactant cellulase enzymolysis solid is added. Sodium hydroxide solution is added into lignocellulose raw material. Solid-liquid separating process is carried out. Dried wood cellulose raw material, the non-ionic surface active agent and polyethylene glycol 6000 are added, followed by centrifuging and separating to obtain a reducing sugar.    USE - Method for degrading lignocelluloses raw material.    ADVANTAGE - The method enables degrading lignocelluloses raw material with lowered crystallinity degree, shortened pretreatment time and improved pretreatment effect.    DETAILED DESCRIPTION - A lignocelluloses raw material degrading method involves crushing a lignocellulose raw material with a cationic surfactant hexadecyl trimethyl ammonium bromide, sodium hydroxide alkali solution followed by subjecting to normal pressure microwave processing solid-liquid separation. An auxiliary non-ionic surfactant cellulase enzymolysis solid is added to the mixture to obtain a sugar solution. The lignocellulose raw material is dried and sieved with 40-60 screens. A 0.5-2.5 % sodium hydroxide solution, a lignocellulose and the sodium hydroxide solution are prepared followed by sieving raw materials and certain amount of the cationic surfactant hexadecyl trimethyl ammonium bromide, 15-45 ml/g lignocellulose raw material and the cationic surfactant hexadecyl trimethyl ammonium bromide. The sodium hydroxide solution is added into 0.04-0.12/g lignocellulose raw material. A normal pressure microwave heating process is performed at frequency of 2450 MHz, power of 160-800 W for 4-22 minutes. A solid-liquid separating process is carried out followed by washing the lignocellulosic residue till the filtrate is neutral, drying at 65 degrees C. The dried wood cellulose raw material, the non-ionic surface active agent and 0.5 % polyethylene glycol 6000 (PEG6000) are added into certain amount of cellulose followed by adding certain amount of a buffer solution, where the buffer solution is added in an amount of 20-50 ml/g of lignocellulose raw material under the condition of rotating speed of 140-160 r/min to hydrolyze for 24-48 hours in a water bath at 40-50 degrees C, followed by centrifuging and separating to obtain a reducing sugar with rotating speed of 4000-5000 r/min for 10-15 minutes.
