Description

Verfahren zur Nutzbarmachung des Schwefels aus Abfällen der Viskoseseidenfabrikation. Die Erfindung betrifft eine weitere Ausbildung des Verfahrens nach Patent 368969. Process for the utilization of sulfur from waste from viscose silk manufacture. The invention relates to a further development of the method according to patent 368969.

Nach diesem Verfahren werden die Abfälle der Viskoseseidenfabrikation zweckmäßig unter Zusatz von bestimmten Salzen einer Koagulation durch Erhitzen unterworfen. Es hat sich nun gezeigt, daß, wenn man den Abfällen beim Erhitzen außer den Salzen Metalloxyde, wie Eisenoxyd, Nickeloxyd o. dgl., zusetzt, der durch die Kohlensäure der Luft aus dem wasserunlöslichen Xanthat häufig entstehende Schwefelwasserstoff infolge katalytischer Sauerstoffübertragung in statu nascendi oxydiert wird. Als ganz besonders vorteilhaft hat sich der Zusatz von Superoxyden, wie Mangansuperoxyd, Natriumsuperoxyd, Bariumsuperoxyd, erwiesen. Man kann auch sauerstoffabgebende Mischungen verwenden. Ebenso kann man auch Mischungen von Oxyden und Superoxyden benutzen. Ferner können noch Stoffe zugesetzt werden, welche die katalytische Sauerstoffübertragung beschleunigen, wie Tierkohle, Zuckerkohle, Eisenfeilspäne. Das Verfahren läßt sich auch in der Weise durchführen, daß man lediglich Stoffe zusetzt, die imstande sind, eine katalytische Sauerstoffübertragung einzuleiten, d. h. also, es können die obenerwähnten Salze fortgelassen werden.According to this process, the waste from the viscose silk manufacturing process expediently subjected to coagulation by heating with the addition of certain salts. It has now been shown that if you take the waste when heating other than the salts Metal oxides, such as iron oxide, nickel oxide or the like, added to the carbonic acid Hydrogen sulfide which is often formed in the air from the water-insoluble xanthate is oxidized as a result of catalytic oxygen transfer in statu nascendi. as The addition of superoxides, such as manganese superoxide, has proven to be particularly advantageous Sodium peroxide, barium peroxide, proven. Oxygen-releasing mixtures can also be used use. Mixtures of oxides and superoxides can also be used. In addition, substances can also be added which promote catalytic oxygen transfer accelerate, such as animal charcoal, sugar charcoal, iron filings. The procedure can be also carry out in such a way that one only adds substances that are capable of initiate catalytic oxygen transfer, d. H. so, it can do the above Salts are omitted.

Der auf diese Weise abgeschiedene Schwefel kann dann in irgendeiner geeigneten Art und Weise wiedergewonnen werden.The sulfur deposited in this way can then be used in any be recovered in a suitable manner.

Das Verfahren eignet sich besonders für den Fall, daß die koagulierten Abfälle nicht wieder im Fabrikationsprozehi Verwendung finden, sondern beispielsweise durch Vergraben beseitigt werden sollen.The method is particularly suitable for the case that the coagulated Waste cannot be reused in the manufacturing process, but for example to be eliminated by burying.
