Abstract

Beim einstufigen alkalischen Sauerstoffaufschluss von Einjahrespflanzen, vorzugsweise Stroh wird das Ziel verfolgt, Energie, Wasser und Chemikalien einzusparen und den apparativen Aufwand zu senken, indem der Hydromodul auf Werte unter 2,5 gesenkt wird. Dies wird erreicht, indem dem Aufschlussgefaess vor Beginn des Aufschlusses Luft vorzugsweise bis zu einem Ueberdruck von 1,0 bis 1,4 MPa zugefuehrt und sodann der Aufschluss unter den ueblichen Bedingungen vorgenommen wird.
