Description

Verfahren zum mischen fein verteilter Kohle mit einem Bindemittel für die Brikettbereitung. Für diese Anmeldung ist gemäß dem Unionsvertrage vom 2. Juni igii die Priorität auf Grund der Anmeldung in Großbritannien vom 21. August 1921 beansprucht. Nach dem in der britischen Patentschrift 155875 beschriebenen Verfahren werden in Wasser in der Schwebe gehaltene Kohlenteilchen mit einem verflüssigten Bindemittel heftig gerührt, so daß sie mit dem Bindemittel überzogen und zu Flocken geballt werden, worauf sie leicht aus dem Wasser abgeschieden werden können.Method for mixing finely divided coal with a binder for the preparation of briquettes. According to the Union Treaty of 2. June igii priority due to registration in Great Britain on August 21st Claimed in 1921. According to that described in British Patent 155875 Process are carbon particles held in suspension in water with a liquefied Binder vigorously stirred so that it is coated with the binder and into flakes are concentrated, whereupon they can easily be separated from the water.

Es wurde nun gefunden, daß Pech, wenn es in geschmolzenem Zustand mit Naphthalin gemischt wird, bei gewöhnlicher Lufttemperatur flüssig, aber viskos verbleibt. Durch eine sehr geringe Erwärmung schmilzt es vollständig. Dieser Stoff wird nach- der Erfindung als Bindemittel verwendet.It has now been found that pitch when it is in a molten state is mixed with naphthalene, liquid but viscous at normal air temperature remains. With very little heating, it melts completely. This stuff is used according to the invention as a binder.

Bei der Ausführung des Verfahrens wird der Trübe bei normaler Lufttemperatur ein geringer Anteil dieses Bindemittels zugesetzt. Beim Rühren überzieht das Bindemittel die Kohlenteilchen, worauf eine intensive Ausflockung stattfindet. Führt man die ausgeflockte Kohle in eine Presse, ebenfalls bei nor. oraler Lufttemperatur, ein und setzt sie einem Preßdruck aus, so wird ein ausgezeichnetes Brikett erzielt, das im wesentlichen frei von Feuchtigkeit ist. Die Brikette sind hart und haltbar und werden mit der Zeit noch härter; es hat sich auch herausgestellt, daß das Naphthalin daraus verflüchtigt wird. Bei den angestellten Versuchen wurde gefunden, daß, wenn Naphthalin mit geschmolzenem Pech im Verhältnis von einem Teil Naphthalin zu 3 bis .4 Teilen Pech gemischt wird, die Mischung lange Zeit flüssig bleibt; wird aber gepulverte Kohle zugeführt, so erfolgt Erstarrung in kurzer Zeit. Wohlverstanden, ist diese Erfindung anwendbar auf das Brikettieren fein verteilter Kohle aus verschiedenen Quellen; besonders brauchbar ist das Verfahren zur Herstellung von Briketten aus Kohlenkonzentraten des Schaumschwimmverfahrens. indem diese Konzentrate bereits mit Wasser gemischt sind.When carrying out the procedure, the pulp becomes at normal air temperature a small amount of this binder is added. The binder coats when the mixture is stirred the coal particles, whereupon intensive flocculation takes place. Do you lead the flocculated coal in a press, also at nor. oral air temperature, a and if it is subjected to pressure, an excellent briquette is obtained, which is essentially free of moisture. The briquettes are hard and durable and get harder over time; it has also been found that the naphthalene from it is volatilized. In the trials made, it was found that if Naphthalene with molten pitch in the ratio of one part naphthalene to 3 to .4 parts of pitch is mixed, the mixture remains liquid for a long time; but will If powdered coal is supplied, solidification takes place in a short time. Of course this invention is applicable to briquetting finely divided coal from various Sources; the process for making briquettes is particularly useful Carbon concentrates of the foam swimming process. by these concentrates already are mixed with water.

Statt Naphthalin kann Phenanthren benutzt werden. Unter Pech soll auch das bei der Erdöldestillation entfallende Pech verstanden . werden. Als fein verteilte Kohle soll jede Art Kohle verstanden werden, deren Körnung in den Brikettierverfahren oder beim Schaumschwimmverfahren verwendbar ist.Phenanthrene can be used instead of naphthalene. Under bad luck should also understood the pitch that is lost in petroleum distillation. will. As fine Distributed coal is to be understood as any kind of coal whose grain size is used in the briquetting process or can be used in the foam swimming process.
