Description

Verfahren zur Extraktion von Öl aus Abläufen der Kohleverflüssigung oder deren Destillationsrückständen Es ist bekannt, daß durch Behandeln mit schwefliger Säure Kohlenwasserstoffe in gesättigte und ungesättigte zerlegt werden können, ferner, daB die Extraktion von Kohle und Torf einen dickflüssigen Extrakt liefert, jedoch nur in Ausbeuten von 0,5o/..Process for extracting oil from coal liquefaction processes or their distillation residues It is known that by treating with sulphurous Acid hydrocarbons can be broken down into saturated and unsaturated, furthermore, that the extraction of coal and peat produces a thick extract, however only in yields of 0.5o / ..

Es ist aber noch nicht gelungen, ein Material, das neben Ölen reich an kohligen und mineralischen Bestandteilen ist, mit SO, zu zerlegen. However, it has not yet been possible to use SO to break down a material that is rich in carbonaceous and mineral components in addition to oils.

Es wurde nun gefunden, daB man schweflige Säure vorzüglich zur Zerlegung der Abläufe der Kohleverflüssigung und der Destillationsrückstände von Abläufen der Kohleverflüssigung benutzen kann.It has now been found that sulphurous acid is an excellent choice for decomposition the processes of coal liquefaction and the distillation residues of processes can use coal liquefaction.

DaB eine solche Extraktion mit sehr gutem Erfolg möglich sein würde, war nicht ohne weiteres vorauszusehen, da z. B. die Extraktion mit Benzol auch nach 14 Tagen das Material nicht erschöpft hatte (M. Heyn und M. Dunkel in Brennstoffchemie 1926, 2, 22).That such an extraction would be possible with very good success, could not be foreseen without further ado, since z. B. the extraction with benzene also after 14 days had not exhausted the material (M. Heyn and M. Dunkel in fuel chemistry 1926, 2, 22).

Diese neuartige Verwendung der schwefligen Säure stellt einen erheblichen technischen Fortschritt dar.This novel use of sulphurous acid represents a significant one technical progress.

Beispiel 1 500 g Berginrückstand E.P. 50° werden in kleinen Stücken im Mischer der Edeleanuapparatur, die unten mit einer Filterplatte versehen ist, mit schwefliger Säure zwei- bis dreimal behandelt. Auf dem Filter bleibt eine schwarze pulverige Masse, die an Benzol fast nichts mehr abgibt. Der Extrakt stellt ein schwerflüssiges Öl dar. Ausbeute 26o g.Example 1 500 g of Bergin residue EP 50 ° are treated in small pieces in the mixer of the Edeleanu apparatus, which is provided with a filter plate at the bottom, with sulphurous acid two to three times. A black powdery mass remains on the filter, which emits almost no benzene. The extract is a heavy oil. Yield 26o g.

Beispiel 2.Example 2.

22o g Berginrückstand, der vorher mit Benzol extrahiert war, aber laut Analyse noch immer etwa 2o bis 25 % Öl enthielt, wurde mit S02 wie in Beispiel i behandelt. Ausbeute an Extrakt 50 g.220 g of Bergin residue, which had previously been extracted with benzene but, according to analysis, still contained about 20 to 25% oil, was treated with SO 2 as in Example i. Yield of extract 50 g.

Beispiel 3 iooo g Berginablauf werden mit Mischer mit S02 gut durchgemischt und filtriert; zur vollständigen Extraktion wird die Behandlung mit S02 wiederholt. Ausbeute 65o g Öl.Example 3 100 g of Bergin drainage are mixed thoroughly with SO2 using a mixer and filtered; the treatment with SO2 is repeated for complete extraction. Yield 65o g of oil.
