Description
Verfahren zur Gewinnteig von Extrakten von Ölschiefern, Braun- und Steinkohlen. In der Literatur sind verschiedene Verfahren angegeben, um aus Ölschiefern, Braun-und Steinkohlen durch Extraktion mit verschiedenen Extraktionsmitteln, z. B. Benzol oder Pvridin, mehr oder minder wertvolle Einzelbestandteile der vorerwähnten Stoffe zu gewinnen. Diese Verfahren haben bisher technische Bedeutung deswegen nicht erlangt, weil die 'Menge des extrahierten Produktes verhälinismäßig gering gewesen ist. Es wurde gefunden, claß man zii wesentlich höheren Ausbeuten an Extraloten kommen kann, wenn inan die Isxtraktion mit den hydrierten Naplithalinen, im besonderen mit Tetrahydronaphthalin (Tetralin), bei erhöhten Temperaturen und Drucken vornimmt. Diese Stoffe erweisen sich als ganz besonders hervorragende Lösungsmittel für viele in den Olschiefern, Braun- und Steinkohlen bereit vorhandenen oder bei der Extralotion sich neu bildenden Stoffe.Process for making dough from extracts of oil shale, brown and brown Hard coals. Various methods are given in the literature to extract from oil shale, Brown and bituminous coals by extraction with various extraction agents, e.g. B. benzene or pvridine, more or less valuable individual components of the aforementioned To win fabrics. For this reason, these processes have not yet been of technical importance obtained because the amount of the extracted product was relatively small is. It has been found that there are significantly higher yields of extra lots can come when the extraction with the hydrogenated naplithalins, in particular with tetrahydronaphthalene (tetralin), at elevated temperatures and pressures. These substances prove to be particularly excellent solvents for many in the oil slates, brown and hard coals already available or with the extra lotion newly forming substances.
Die Anwendung von hydrierten Naphthalinen zur Gewinnung von Erdwachs, Paraffin u. dgl. durch Extraktion ist durch die Patentschrift 32o8o7, Kl. 22h, bereits bekannt. Es ergibt sich aber, daß die Anwendung von höheren Temperaturen und Drucken die Extraktionswirkung der hydrierten \Zaphthaline ganz besonders steigert, so daß erst durch die Anwendung von erhöhtem Druck und Temper atur ein wesentlich technischer Effekt gegenüber der Extraktion bei gewöhnlicher Temperatur erreicht wird. Beispiel I: Olschiefer ergab bei der Behandlung mit Tetralin bei 25oy eine Extraktausbeute von r9,9 Prozent, bei loo' eine solche voll o,g Prozent und mit Benzol bei 2401 eine 1,xtralotausbeute von 2 Prozent.The use of hydrogenated naphthalenes for the extraction of earth wax, Paraffin and the like by extraction is already known from patent specification 32o8o7, class 22h known. It turns out, however, that the use of higher temperatures and pressures the extraction effect of the hydrogenated \ Zaphthalenes particularly increases, so that only through the use of increased pressure and temperature does it become much more technical Effect over extraction at ordinary temperature is achieved. example I: Oil slate gave an extract yield of 25% when treated with tetralin of r9.9 percent, at loo 'such a full o, g percent and with benzene at 2401 a 1. xtralot yield of 2 percent.
Beispiel 11: Eine mitteldeutsche Schwelkohle ergab bei Druckextraktion mit Tetralin ],ei 215° 15,2 Prozent, mit siedendem Tetralin 9,3 Prozent Extraktausbeute, während bei der Druckextraktion mit Benzol bei 215° 7,6 Prozent und mit siedendem Benzol bei normalem Druck 7,2 Prozent Extralot gewonnen werden konnten.Example 11: A Central German black coal resulted in pressure extraction with tetralin], ei 215 ° 15.2 percent, with boiling tetralin 9.3 percent extract yield, while in the pressure extraction with benzene at 215 ° 7.6 percent and with boiling Benzene at normal pressure 7.2 percent extra lot could be obtained.
Beispiel III: Eine böhmische, bituinenreiche Braunkohle ergab bei der Druckextraktion mit Tetralin bei 25o1 37,¢ Prozent, bei Siedetemperatur des Tetralins bei normalem Druck 17 Prozent E xtraktausbeute.Example III: A bohemian, bitumen-rich brown coal yielded the pressure extraction with tetralin at 25o1 37. [percent, at the boiling point of the Tetralins at normal pressure 17 percent extract yield.
BeispielIV: Eine Casseler Braunkohle wies bei der Druckextraktion mit Tetralin bei 22o1 eine Extraktausbeute von 22,2 Prozent, bei der Extraktion mit siedendem Tetralin bei normalem Druck eine solche von 5,2 Prozent auf, während sich bei Druckextraktion mit Benzol bei 2zo° 4,6 Prozent und bei der Extraktion mit siedendem Benzol bei normalem Druck 2,8 Prozent Extraktausbeüte ergaben.Example IV: A Casseler lignite showed an extract yield of 22.2 percent in the pressure extraction with tetralin at 22o1, in the extraction with boiling tetralin at normal pressure a yield of 5.2 percent, while in the pressure extraction with benzene at 2zo ° 4, 6 percent and the extraction with boiling benzene at normal pressure gave 2.8 percent extract yield.
Die durch die Druckextraktion mit hydrierten N'aphthalinen erzielbaren Produkte können in bekannter Weise auf wertvolle Schmieröle, Paraffin, Montanwachs u. dgl. aufgearbeitet werden.Those achievable by pressure extraction with hydrogenated naphthalenes Products can be based on valuable lubricating oils, paraffin and montan wax in a known manner and the like. Be worked up.
