METHOD FOR PRODUCING ETHANOL FROM RAW MATERIAL CONTAINING CASSAVA RESIDUES

摘要

A method for producing ethanol from raw material containing cassava residues comprises the steps of: mixing raw material containing cassava residues with enzyme, and enzymolyzing the cellulose in the raw material to give enzymolysis product, wherein the mixing of the enzyme and the raw material comprises mixing the raw material and the enzyme in batches, the batch number is at least two, and each batch of the raw material is added at the amount of at most 60wt% of the total raw material; and fermenting the enzymolysis product. The inventive method can increase utilization rate of the raw material containing cassava residues, and has high ethanol yield.
