| description | 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. %.
L'invention porte sur un procédé d'obtention d'alcool éthylique à partir de la cellulose des plantes annuelles et pérennes. La cellulose coupée est hydrolysée avec une solution acide telle que l'acide sulfurique. Les produits d'hydrolyse sont exposés à une base telle que l'hydroxyde d'ammonium du fait de la neutralisation de l'acide (pH compris entre 6 et 7). Les phases solides et liquides sont séparées et la phase liquide contenant la solution sucrée est mise à fermenter avec de la levure de bière, et lorsque la fermentation est achevée, l'alcool éthylique est distillé, sous forme de produit final, à une concentration de 96,7 % en volume. |
