The present study aims to study the possibility of using ordinary cane as a plant renewable raw material for the production of bioethanol with the use of preliminary hydrolysis treatment of raw materials with weak solutions of sulfuric acid, which allows the conversion of cellulose material into monosaccharides. The comparison of the yield of ethanol obtained from cane subjected to pretreatment and without pretreatment was carried out. It is shown that pretreatment of cane raw materials with dilute sulfuric acid (0.5%) at 140 ° C for 1 hour, allows to obtain more concentrated ethanol solutions after fermentation, compared with cane without pretreatment.
