Description

Verfahren zur Erhöhung der Bindekraft des Brikettpechs, Man hat bereits versucht, die bei der Teerschmierölgewinnung abfallenden Anthrazenrückstände, die hauptsächlich aus Phenanthren, Karbazol und anderen festen zur Zeit nicht verwertbaren Kohlenwasserstoffen bestehen, dadurch zu verwerten, daß man sie in den Teerdestillationen dem heißen Pech zusetzte, um das Pech zu beleben. Das Verfahren hatte aber den Nachteil, daß das so gewonnene Pech nach dem Erkalten an. Bindekraft nicht unerheblich abnahm und infolgedessen für- die Brikettierung minderwertig wurde.Method for increasing the cohesiveness of the briquette pitch, one already has tries to remove the anthracene residues that fall off during the extraction of tar oil mainly from phenanthrene, carbazole and other solid materials that cannot be used at the moment There are hydrocarbons that can be used by using them in the tar distillations added to the hot pitch to animate the pitch. However, the procedure had the disadvantage that the pitch won in this way after cooling down. Binding power decreased not insignificantly and as a result for- the briquetting became inferior.

Durch angestellte Versuche im Großbetrieb hat sich nun gezeigt, daß die bei der Teerschmierölgewinnung abfallenden Anthrazenrückstände nur dann zur Erhöhung der Bindekraft des bei der Brikettierung als Bindemittel verwendeten Pechs geeignet sind, wenn sie dem flüssigen Pech unmittelbar vor der Brikettierung zugesetzt werden und die Pechmasse kurz nach erfolgter Auflösung der Rückstände sofort dem Brikettiergut, z. B. durch Einblasen in zerstäubtem Zustand, zugeführt wird, ohne daß die Mischung vorher erstarrte.Through trials in large companies it has now been shown that The anthracene residues that fall off during the extraction of tar oil are then only used Increase in the binding power of the pitch used as a binding agent in briquetting are suitable if they are added to the liquid pitch immediately before briquetting and the pitch mass immediately after the residues have dissolved Briquette, e.g. B. by blowing in the atomized state, is supplied without that the mixture froze beforehand.

Es genügt hierbei Schon ein kleiner Zusatz von Anthrazenrückständen, um die Bindekraft des Pechs derartig zu erhöhen, daß an Pech wesentlich gespart werden kann.A small addition of anthracene residue is sufficient here, in order to increase the binding power of the pitch in such a way that the pitch is significantly saved can be.

Da es von ausschlaggebender Bedeutung ist, die Anthrazenrückstände erst unmittelbar vor der Brikettierung dem flüssigen Pech zuzusetzen, so hat diese Erfindung z. B. größte Bedeutung für die Ausführung der bekannten Brikettierungsverfahren nach den Patentschriften 263158 und 289o69, bei welchen das Bindemittel bzw. *das flüssige Pech in fein zerstäubter Form dem Brikettiergut direkt zugeblasen wird.Since it is of vital importance, the anthracene residue to be added to the liquid pitch immediately before briquetting, this has to be done Invention z. B. Great importance for the execution of the known briquetting process according to patents 263158 and 289o69, in which the binder or * the liquid pitch in finely atomized form is blown directly into the briquette.
