Die vorliegende Erfindung bezieht sich auf ' ein Verfahren zum Herstellen von Alkohol
aus der Abfallauge in Sulfitfabriken. Das Verfahren besteht darin, daß die Lauge durch
Neutralisieren und Lüften direkt ohne vor-' bereitende Behandlung gärbar gemacht und,
dann vergoren wird. Das Lüften kann vor, während und nach dem Neutralisieren vorgenommen
werden. Im nachstehenden ist gezeigt, wie das Verfahren in der Praxis beispielsweise ausgeführt werden kann.
. Die Lauge wird mit Kalk neutralisiert, wobei der Überschuß · an Kalk mit Kohlensäure
neutralisiert werden kann, mit geeigneter Hefe g'emischt und vergoren, wonach der Alkohol
abdestilliert wird. Das Neutralisieren der Lauge kann auch mit kohlensaurem Kalk oder
Kreide bewirkt werden. Es kann außerdem eine Filtration vorgenommen werden, teils um
den Niederschlag auszunutzen, teils um eine klare Maische zu erhalten; ferner kann ein
Ferment (z. B. ein wenig Malz, welches das erforderliche Ferment enthält) beigemischt
werden, um den Zuckergehalt zu vermehren. Außerdem kann die Lauge mit Torfmoos, Sägespänen o. dgl. bei hoher Temperatur gekocht
werden, um diese Materialien teilweise zu zerlegen und zur Erhöhung des Zuckergehaltes
auszunutzen.The present invention relates to a process for producing alcohol from the waste eye in sulphite factories. The process consists in making the liquor fermentable by neutralizing and ventilating it directly without any preparatory treatment and then fermenting it. Ventilation can be done before, during and after neutralization. The following shows how the method can be carried out in practice, for example.
. The lye is neutralized with lime, the excess lime can be neutralized with carbonic acid, mixed with suitable yeast and fermented, after which the alcohol is distilled off. The lye can also be neutralized with carbonate of lime or chalk. A filtration can also be carried out, partly to utilize the precipitate, partly to obtain a clear mash; a ferment (e.g. a little malt containing the required ferment) can also be added to increase the sugar content. In addition, the lye can be boiled with peat moss, sawdust or the like at a high temperature in order to partially break down these materials and use them to increase the sugar content.
