Description

Verfahren zur Abtrennung anorganischer Bestandteile aus Ölschiefer, Kohle oder Torf Es ist hekanrrt, zur Aufbereitung voai Erzen o- oder p-Chlorpllierrol als Flotationsmittel' zu verwenden. Benutzt man diese Stoffe jedoch, um den Gehalt von kohlen stoffhalbigen Stoffen, wie Öl, schiefer, Kohle oder Torf, an anorganischen Bestandteilen herabzusetzen, so erzielt man nur eine unbefriedigende Wirkung.Process for the separation of inorganic constituents from oil shale, coal or peat It is common practice to use o- or p-Chlorpllierrol as a flotation agent for the processing of ores. However, if these substances are used to reduce the inorganic constituents of carbon-half substances such as oil, shale, coal or peat, the effect is only unsatisfactory.

Es wurde nun gefunden, daB man eine sehr weitgehende Zerlegung von Ölschiefer, Kohle oder Torf in organische und anorganische Bestand:teife erreicht, wenn maul als, Flotabionsmitbel balogenierte, insbesondere chlorierte Kresole verwendet.It has now been found that a very extensive decomposition of Oil shale, coal or peat in organic and inorganic stock: teife achieved, if maul is used as a flotabion medium balanced, especially chlorinated, cresols.

Man behandelt das zu zer.leglende Gut mit der rrehrfavchen. Menge Wasser und einer kleinen Menge eines'hal'agenierten Kresols, wie p-Chlorrm-kresof, z B. mit 8o bis ioo g je Tonne Ausgangsstoff. Durch Einblasen von Luft und Rühren wird für eine gute Schaumbildung gesorgt. Diese läflt sich noch verbessern, wenn man unter Zusatz von Seifenlösung arbeitet. Neun inan ölschief-er in dieser Weise behandelt, sc enthält er tim etwa 10 biis 200/0 weniger aniorg@aiiisclie Bestandteile als bei der Flotation mit den bisher bekannten Flotationsinitteln, Die I?rmedrigu.tng des Gehaltes an anorgannsclien Bestandteilen ist von besonderer Bedeutung, wenn der _1usgangsitotf, z. B. Kohle, der F)rtick'h_vdrieruirg unterworfen werden soll.The goods to be dismantled are treated with the rrehrfavchen. Amount of water and a small amount of a'hal'agenierten cresol, such as p-Chlorrm-kresof, e.g. with 80 to 100 g per ton of starting material. Good foaming is ensured by blowing in air and stirring. This can be improved if you work with the addition of a soap solution. Nine in an oil slab treated in this way, it contains about 10 to 200/0 less organic constituents than in flotation with the previously known flotation agents. The reduction in the content of inorganic constituents is of particular importance , if the _1usgangsitotf, z. B. Coal to be subjected to F) rtick'h_vdrieruirg.

Verwendet man an Stelle von p-Cli@lor-in-kre,sol die gleiche -Menge o- oder p-Chlorphenol, so kann man unter sonst gleichen Bedingungen nur 390/0 der organischen Stoffe des (>Ischiefers zusammen mit dem Schaum entfernen.If you use the same amount instead of p-Cli @ lor-in-kre, sol o- or p-chlorophenol, one can only use 390/0 of the Remove organic substances from the (> is slate together with the foam.
