Dr. ERNST JAGOBY in MÜNCHEN. Verfahren zur Entgiftung von Zellstoffablauge. Dr. ERNST JAGOBY in MUNICH. Process for the detoxification of pulp waste liquor.

Zusatz zum Patent 307383.Addendum to patent 307383.

Patentiert im Deutschen Reiche vom 9. Februar 1918 ab. Längste Dauer: 24.November 1931.Patented in the German Empire on February 9, 1918. Longest duration: November 24, 1931.

Bei weiterer Verfolgung des Verfahrens nach Patent 307383 ergab sich, daß die adsorbierend und entgiftend wirkenden Stoffe auch zugesetzt werden können, bevor die Lauge neutralisiert ist.When the method according to patent 307383 was followed, it was found that the adsorbent and detoxifying substances can also be added before the lye is neutralized.

Eine Lüftung der Lauge zwecks Herabsetzung ihres Gehaltes an schwefliger Säure bzw. Sulfiten ist nicht "erforderlich.Ventilation of the lye to reduce its sulphurous acid content or sulfites is not "required.

Man arbeitet beispielsweise so, daß 500 Teile Ablauge mit 1 Teil ioprozentiger Huminlösung durchgerührt, dann 1 Teil ioprozentige Alaunlösung beigegeben und mit Kreide unter Erwärmen auf 500 C neutralisiert wird.For example, it operates so that 500 parts with 1 part of waste liquor stirred ioprozentiger Huminlösung, then added to 1 part ioprozentige alum solution and is neutralized with chalk with heating at 50 0 C.

Das Filtrat wird mit Bierhefe versetzt und 80 Stunden bei 280C unter gelegentlichem Rühren vergoren. Die Ausbeute betrug z. B. 1,15 Vol. Prozent Sprit, während bei Parallelversuchen, bei denen die Humin-Alaunbehandlung nicht durchgeführt wurde, nur 0,95 Vol. Prozent Spiritus erhalten wurden.The filtrate is mixed with brewer's yeast and fermented for 80 hours at 28 ° C. with occasional stirring. The yield was e.g. B. 1.15 percent by volume of fuel, while in parallel tests in which the humin-alum treatment was not carried out, only 0.95 percent by volume of alcohol was obtained.
