Description
Verfahren zur Aufarbeitung der bei der Verkokung von Pech entstehenden Destillate: Bei der Verkokung von Pech, d. h. der Destillationsrückstände von Braunkohlenteer und insbesondere- Steinkohlenteer, entstehen neben dem als Hauptprodukt anfallenden Pechkoks flüchtige Destillate, die kondensiert und gesammelt werden, jedoch sich nur als minderwertige Öle für Heizzwecke verwenden ließen. Auch wurden gelegentlich diese Kondensate nochmals destilliert, wobei ein Redestillat und als Rückstand Pech gewonnen wurden. Es resultierten hierbei im besten Falle 5o% desAusgangsproduktes als minderwertiges Pech.Process for the processing of the resulting from the coking of pitch Distillates: In the coking of pitch, i.e. H. the distillation residues of lignite tar and especially coal tar, are produced alongside the main product Pitch coke volatile distillates that are condensed and collected, however only allowed to be used as inferior oils for heating purposes. Also were occasional these condensates are distilled again, a redistillate and pitch as residue were won. In the best case, this resulted in 50% of the starting product as inferior bad luck.
Es hat sich nun erwiesen, da.ß es möglich ist, diese Pechausbeute ganz erheblich bis auf 932/0 und mehr zu erhöhen unter Verbesserung der Qualität, wenn die Verkokungsdestillatezunächst auf etwa 3oo° erhitzt werden und dann mit Sauerstoff oder vorzugsweise Luft oder anderen sauerstoffhaltigen Gasen behandelt werden. Der Sauerstoff wird absorbiert unter Umlagerung und Polymerisation des Öles, und es entsteht ein glänzendes, nicht sehr sprödes Pech.It has now been shown that it is possible to produce this pitch to increase quite considerably up to 932/0 and more while improving the quality, when the coking distillates are first heated to about 3oo ° and then with Treated oxygen or preferably air or other oxygen-containing gases will. The oxygen is absorbed with rearrangement and polymerization of the oil, and the result is a shiny, not very brittle pitch.
Das Verfahren hat noch den .besonderen Vorteil, daß der Aufwand an Wärme sehr gering ist, da der Prozeß exothermisch verläuft. Nachdem das Destillat auf etwa 3oo° erhitzt ist, genügt die durch das Einblasen von z. B. Luft frei werdende Wärme, um den Prozeß his zum Ende durchzuführen ohne Zuführung weiterer Wärmemengen.The method also has the special advantage that the effort involved Heat is very little because the process is exothermic. After the distillate is heated to about 3oo °, is sufficient by blowing z. B. Air released Heat to carry out the process to the end without adding more heat.
Das erhaltene Pech ist deshalb besonders wertvoll, ereil es einen sehr geringen Aschegehalthat und daher für alle solche Zwecke besonders gut geeignet ist, bei denen auf diese Eigenschaft Wert gelegt wird (Pechverkokung usw.).The pitch obtained is therefore particularly valuable if it happens to you has a very low ash content and is therefore particularly suitable for all such purposes where value is placed on this property (pitch coking, etc.).
Es ist an sich bekannt, Teer und Teeröle in der Wärme mit Luft, Sauerstoff oder ozonisierter Luft zu behandeln, bis der Rückstand in der Kälte pechartige Konsistenz besitzt. Nicht bekannt war es, die bei der Verkokung von Pech entstehenden Destillate in der Wärme mit Sauerstoff zu behandeln, und es war nicht vorauszusehen, da.ß diese nicht zur Pechbildung neigenden Stoffe in Pech übergeführt werden können.It is known per se, tar and tar oils in the heat with air, oxygen or treat ozonized air until the residue in the cold is pitch-like consistency owns. It was not known about the distillates produced by the coking of pitch to be treated with oxygen in the warmth, and it was not foreseeable that this would occur substances that do not tend to form pitch can be converted into pitch.
