The invention discloses a raw material microwave pretreatment method used for the production of fuel alcohol, and relates to a raw material pretreatment method before producing the fuel alcohol. The invention solves the disadvantages that the cost is too high, the energy consumption is too large, or the conditions are too severe, etc., and the problems that the production cycle is long, and secondary pollution is caused. The invention has the following steps: 10 g of matrix powder after water equilibrium is taken, and is filled with water according to a solid to liquid ratio of 1:30 to 50, andis put into a microwave treater, pretreatment is performed in the condition of 00 to 1000 W for 30 to 60 min, then wshing and filtering are performed, and the pretreatment is finished. Under the premise of ensuring the pretreatment effect, the invention simplifies the technical process, reduces the treatment time, reduces the production energy consumption and the cost, simultaneously does not cause secondary pollution, and is easy to realize industrial application. The optimal conditions of the invention are obtained by respectively optimizing the liquid to solid ratio, the heating time and the microwave power, and 49.1 percent of glucose conversion rate, 21.1 percent of xylose conversion rate, and 76 percent of theoretical ethyl alcohol yield rate are respectively abtained under the optimal conditions.
