Description
Verfahren zur Zerlegung von Teeren bzw. Teerölen in Pechstoffe und Öle ohne Destillation. Es ist vor-eschla-en, Hochtemperaturteer, Schwelteer und ähnliche bittiminöse Flüssigkeiten bzw. Anteile derselben durch Behandeln mit organischen, nicht aromatischen Lösungsmitteln, wie Benzin u. dgl., von Pech-bzw. Asphaltstoffen dergestalt zu befreien, daß die durch die Behandlung entstandenen pechähnlichen Ausscheidungen abfiltriert bzw. in üblicher Weise getrennt werden.Process for breaking down tars or tar oils into pitch substances and Oils without distillation. It is pre-sleep, high temperature tar, smoldering tar and similar bitiminous liquids or parts thereof by treatment with organic, non-aromatic solvents, such as gasoline and the like, from pitch or. Asphalt materials to free in such a way that the pitch-like resulting from the treatment Excretions are filtered off or separated in the usual way.
Es hat sich nun gezeigt, daß solche von Asphaltstoffen befreite öle häufig immer noch Neigung haben (besonders bei längerem Stehenlassen an der Luft), nachzudicken bzw. Pechstoffe erneut zu 1,ilden, da ja nur die ursprünglich vorhandenen Aspbaltstoffe entferiit wurden, nicht aber die in der Flüssigkeit vorhandenen, zur Asphaltbildung neigenden sogenannten Asphaltbildner. Dieser Mißstand läßt sich gemäß vorliegender Erfindung beseitigen, wenn man vor der Behandlung der teerigen Flüssigkeit iiiit den oben beschriebellen organischen Lösungsmitteln dieselbe am Rückflußkühler kürzere Zeit auf Temperaturen, die mehr oder weniger über 6o' liegen, erhitzt. Vorhandene Asphaltbildner polymerisieren dabei unter Asphaltbildung, so daß bei der nunniehr- nach der Abkühlung auf die jeweils benötigteTemperatur erfolgenden Behandlung mit dem Lösungsmittel die gesamten Asphaltstoffe abgeschieden werden (d. h. sowohl die ursprünglich vorhandenen als auch die in demAusgangsmaterial lediglich als Asphaltbildner vorkommenden Peclistoffe). Die einfache Erhitzung am Rückflußkühler läßt sich beschleunigen, wenn man während dieser Temperaturbehandlung dauernd oder auch nur zeitweise kleine Mengen Wasserdampf durch die Flüssigkeit durchleitet. Die in dem Wasserdampf meist enthaltenen kleinsteil Mengen Sauerstoff wirken besonders günstig auf die Überführung der Asphaltbildner in Asphaltstoffe. Aus dem evtl. abziehenden Teerwasserdampfgemisch können in bekannter Weise die Teeranteile durch Abkühlung wiedergewonnen werden.It has now been shown that such asphalt-free oils often still have a tendency (especially if left to stand in the air for a long time), to thicken or pitch substances again to 1, since only those originally present Asphalt substances were removed, but not those present in the liquid So-called asphalt-forming agents tend to form asphalt. This deficiency can be according to Eliminate the present invention if one prior to treating the tarry liquid iii with the above-described organic solvents do the same on the reflux condenser for a shorter time to temperatures which are more or less above 6o ', heated. Existing Asphalt formers polymerize to form asphalt, so that in the after cooling to the required temperature, treatment with the solvent removes all of the asphalt (i.e. both the originally present as well as those in the starting material only as an asphalt former occurring pecli substances). The simple heating on the reflux condenser can be accelerated, if during this temperature treatment one continuously or only occasionally small Passes quantities of water vapor through the liquid. The ones in the steam mostly The small amounts of oxygen contained have a particularly beneficial effect on the transfer the asphalt former in asphalt materials. From the tar water vapor mixture that may be withdrawn the tar can be recovered in a known manner by cooling.
