Abstract

Die Erfindung betrifft ein Vorbehandlungsverfahren aus hegoctischer Zellulose, bei dem der Rohstoff aus Holzzellulose nach dem Entbrünen, Trocknen und Zerkleinern mit EDTA-2Na vermischt, deionisiertes Wasser hinzugefügt und die Temperaturrührreaktion 1 bis 3 Stunden unter Bedingungen von 25 bis 35 Grad C, der vorgewaschenen Kannose, gehalten wird; Die Erfindung, die von EDTA-2Na vorgewaschen wurde, eliminiert die katalytische Risswirkung von Metallionen auf Wasserstoffperoxid, minimiert den unnötigen Verbrauch von Wasserstoffperoxid und das Vorhandensein von Magnesium/Zink-Ionen und Eisenionenplasma im System hemmt Die Cellulase in einem bestimmten Konzentrationsbereich, so dass Wasserstoffperoxid vollständig auf Lignotin wirkt, was die Umwandlungsrate von Lignokosese erheblich verbessern kann.
