Abstract

Invenţia se referă la un procedeu de producere a etanolului din componentul celulozic al deşeurilor urbane solide, în care componentul celulozic a fost defibrat, procedeu care cuprinde etapele de: a) tratare a componentului celulozic defibrat cu acid sulfuric concentrat, în raport de 1:1 în greutate, la 30...80°C, pentru a se obţine un amestec hidrolizat parţial; b) diluare a amestecului hidrolizat parţial cu apă la o temperatură de 80...100°C, pentru a se obţine un amestec diluat ce conţine 2 până la 6 părţi apă la o parte de amestec hidrolizat parţial, părţile fiind exprimate în greutate; c) agitare a amestecului diluat, pentru a se obţine un material digestat; d) eliminare a solidelor din amestecul digestat prin filtrare pentru a se obţine un filtrat; e) separare a filtratului într-o soluţie ce conţine acid şi o soluţie ce conţine zaharuri; f) concentrare a soluţiei ce conţine zaharuri până la 12...14% zaharuri; g) ajustare a pH-ului soluţiei concentrate ce conţine zaharuri la valoarea de 6; h) fermentare cu drojdie, a soluţiei obţinută în etapa (g), pentru a se obţine un must de bere; i) îndepărtare a drojdiei din mustul de bere, pentru a se obţine un must de bere filtrat, şi j) recuperarea etanolului din mustul de bere.
