Abstract The alcohol producing process with plant fiber material includes the steps of crushing; hydrolysis by adding 0.5-1.5% concentration dilute sulfuric acid to prepare digest and wood fiber dregs; filtering of the digest and concentration into 5-10% concentration pentaose liquid; enzymolysis and fermentation of wood fiber dregs for 24 hr to prepare fermented liquid containing 2-5% alcohol; strain culture in Erlenmeyer flask on mechanical shaker at 30 deg.c and oxygen adding fermentatino in seed tank to obtain fermented liquid; fermententing culture of the fermented liquid and pentaose liquid mixture in fermentation tank to prepare fermented liquid; and three-tower distillation of the fermented liquid containing 2-5 % of alcohol to obtain alcohol. The process has less steps, low cost, high efficiency and no environmental pollution.
