The procedure for obtaining ethyl-alcohol from cellulose of annual and perennial plants is described here. The chopped cellulose material is hydrolysed with the acid solution, such as sulphuric acid. The products of hydrolysis are exposed to the base, such as ammonium hydroxide, because of the neutralization of acid (a pH between 6 and 7). Solid and liquid phases are separated and liquid phase containing the sugar solution is being fermented with brewers' yeast, and when fermentation is completed ethyl-alcohol as its final product is distilled to concentration of 96.7 vol. %. |
