Abstract
Die Erfindung betrifft ein Verfahren zur Herstellung von Zellstoff aus Stroh, welches in Gegenwart von Sauerstoff arbeitet und aus einer Stufe besteht. Ihr Ziel ist es, den Aufschluszprozesz durch Einsatz eines geeigneten Alkalispenders so zu gestalten, dasz die Zellulosefaser eine moeglichst schonende Behandlung erfaehrt, jedoch ein voll aufgeschlossener Zellstoff erhalten wird. Dies wird erreicht, indem Stroh unter Verwendung eines Gemisches von Natriumhydroxid und Natriumkarbonat als Aufschluszmittel aufgeschlossen wird.
