Verfahren zur Umwandlung von Kohlenwasserstoffen wie Steinkohlen-, Petroleum-oder
Sehieferteeren in Pech.
Gegenstand des Stammpatentes ist ein Verfahren zur Gewinnung von Pech aus Steinkohlen-, Petroleum-oder Schieferteeren mittels Durchleitens von Luft, welches darin besteht, dass die beim Durchleiten mitgerissenen Gase und Dämpfe wiederholt mit Teermengen zusammengebracht werden, die infolge von verschieden weitgehender Einwirkung von Luft verschiedene chemische Zusammensetzung aufweisen, so zwar, dass die mitgerissenen Gase und Dämpfe so lange der Behandlung mit Luft unterworfen werden, bis sie schliesslich in Pech umgewandelt sind.
Es kann unter Umständen vorteilhaft sein, nur gewisse Bestandteile des Ausgangsmaterials in Pech umzuwandeln und andere nicht umzubilden. So kann es z. B. vorkommen, dass naphtalinhaltige Öle und Naphtalin im Handel zu gewissen Zeiten einen niedrigeren Verkaufspreis erreichen als Pech, während Anthrazenöle einen gleich hohen Preis erreichen, so dass man darauf auszugehen hat, eine möglichst hohe Ausbeute an Pech und Anthrazenölen zu bekommen. Gemäss der Erfindung wird dies dadurch erreicht, dass vor der Umwandlung des Ausgangsmaterials in Pech, die wertvolleren Produkte als das Pech, wie Naphtalin, Anthrazen, Kreosot u. dgl., vom Ausgangsmaterial abgetrenten und entweder als Gemenge oder einzeln gesammelt werden. Man verfährt, zweckmässig unter Verwendung eines Kolonnenapparates, in der Weise, dass die abgehenden Dämpfe und Gase kondensiert und getrennt werden.
Nach dieser Trennung werden diejenigen Fraktionen, welche man vollständig in Pech umwandeln will, in die zu destillierende Masse zurückgeleitet oder in eine zweite Kolonne von niedrigerer Temperatur eingeleitet und nach dem Verfahren gemäss dem Stammpatente weiter behandelt, während die anderen Bestandteile ohne weiteres als Destillationsprodukte gesammelt werden.
Wenn es sich darum handelt, alle Bestandteile, mit Ausnahme eines Bestandteiles oder zweier Bestandteile, umzuwandeln, so wird das Verfahren so weit geführt, bis diese Bestandteile entweder getrennt oder in gemengten Zustand übergegangen sind. Diese Produkte werden dann in geeigneter Weise getrennt und die in Pech umzuwandelnden Produkte wieder in die Teermasse zurückgeleitet oder einer anderen Teerkolonne zugeführt.

Process for converting hydrocarbons such as coal, petroleum or
Seeing tars in bad luck.
The subject of the parent patent is a process for extracting pitch from coal, petroleum or shale tars by passing air through it, which consists in repeatedly bringing together the gases and vapors entrained during the passage with tar quantities that differ as a result of the different effects of air Have chemical composition, so that the entrained gases and vapors are subjected to treatment with air until they are finally converted into pitch.
Under certain circumstances, it can be advantageous to convert only certain components of the starting material into pitch and not to convert others. So it can be For example, it can happen that naphthalene-containing oils and naphthalene in the trade reach a lower retail price than pitch at certain times, while anthracene oils reach the same price, so that one has to assume that the yield of pitch and anthracene oils is as high as possible. According to the invention, this is achieved in that before the conversion of the starting material into pitch, the more valuable products than the pitch, such as naphthalene, anthracene, creosote and the like. Like., separated from the starting material and collected either as a batch or individually. The procedure, expediently using a column apparatus, is such that the outgoing vapors and gases are condensed and separated.
After this separation, those fractions which you want to convert completely into pitch are returned to the mass to be distilled or introduced into a second column at a lower temperature and treated further according to the method according to the parent patent, while the other constituents are readily collected as distillation products .
If it is a question of converting all components, with the exception of one component or two components, the process is carried out until these components have either been separated or passed into a mixed state. These products are then separated in a suitable manner and the products to be converted into pitch are returned to the tar mass or fed to another tar column.
