A process for treating lignocellulosic material comprises the steps of: (1) crushing the lignocellulosic material; (2) mixing the resulting particles with water and dispersing the mixture by means of colloid mill to form a suspension; (3) high pressure homogenizing the suspension to obtain a particle with a particle diameter of 10-40µm; (4) buffering the suspension by using sodium acetate and acetic acid buffer solution, and then adding cellulase, ²-glucosidase and xylanase and performing enzymolysis for 36-72 h.
