Abstract

Opisan je postupak za dobijanje etil alkohola iz celuloze jednogodišnjih ili višegodišnjih biljaka, koji se izvodi tako što se sitno usitnjen celulozni materijal hidrolizuje rastvorom kiseline, kao što je sumporna kiselina, što se proizvodi hidrolize izlažu dejstvu baze, kao što je amonijum hidroksid, radi neutralizacije kiseline do pH izmedju 6 i 7, što se čvrsta i tečna faza razdvoje i tečna faza koja sadrži rastvor šećera izlaže fermentaciji dodatkom pivskog kvasca, a po završetku fermentacije etil alkohol kao njen konačni proizvod destiliše do koncentracije od 96,7 vol%.Described is a process for producing ethyl alcohol from the cellulose of annual or perennial plants, which is performed by hydrolyzing finely divided cellulosic material with an acid solution, such as sulfuric acid, exposing hydrolysis products to a base, such as ammonium hydroxide, to neutralize acids to a pH between 6 and 7, which separates the solid and liquid phases and the liquid phase containing the sugar solution is subjected to fermentation by the addition of brewer's yeast, and after fermentation ethyl alcohol as its final product is distilled to a concentration of 96.7 vol%.
