Verfahren zur Herstellung von Briketts aus Kohle und kohlehaltigen Abfallstoffen mittels Teer.
Die frühesten Versuche zur Herstellung von Briketts aus Steinkohle wurden mit Teer gemacht. Man arbeitete in der Weise, dass Teer und Kohle in Mischmaschinen z. B. in einem senkrechten Mischer (Malaxeur) oder in einer horizontalen Mischschnecke, gemischt und dann verpresst wurden. Entsprechend der flüssigen Beschaffenheit des Teers auch in kaltem Zustande hatten die Briketts nur eine geringe Festigkeit : auch bedurfte es des Zusatzes erheblicher Mengen an Teer.
Die eigentliche Brikettfabrikation, wie sie heute noch besteht, begann daher erst mit der Verwendung von Teerpech als Bindemittel, das bekanntlich gewonnen wird, indem die etwa bis zu 400 C siedenden Bestandteile des Teers (welche bis zu diesem Siedepunkt etwa 50% desselben ausmachen) abdestilliert werden.

Es hat sich nun ergeben, dass man mit Teer irgend welcher Art, auch nllt Dickteer, denselben, ja sogar noch einen besseren Effekt als mit Pech erzielen kann, wenn man die Mischung von Kohle und'ree-einige Zeit intensiv auf einem schweren Kollergang bearbeitet, wobei die anfänglich feuchte Mischung unter dem Druck der Laufer durch das

Es leuchtet ohneweiters ein. dass das vorliegende Verfahren, bei dem in der Regel ohne jede Erhitzung gearbeitet wird, gegenüber dem hekannten Pechverfahren wirtschaftliche und betriebstechnische Vorteile bietet. Die vorliegenden Briketts zeichnen sich, was von grosser Wichtigkeit ist, noch dadurch aus, dass sie in der Hitze weniger leicht erweichen und besser im Feuer stehen.

Process for the production of briquettes from coal and carbon-containing waste materials using tar.
The earliest attempts to make briquettes from coal were made with tar. One worked in such a way that tar and coal in mixing machines z. B. in a vertical mixer (Malaxeur) or in a horizontal mixing screw, mixed and then pressed. Corresponding to the liquid nature of the tar, even when cold, the briquettes had only a low level of strength: considerable quantities of tar had to be added.
The actual briquette production, as it still exists today, therefore only began with the use of tar pitch as a binding agent, which is known to be obtained by distilling off the constituents of the tar which boil up to 400 C (which make up about 50% of the same up to this boiling point) will. In order to be able to mix the solid pitch with the coal as finely as possible and to make the mixture pressable.

capable state transferred. The bond in the briquette then occurs as it cools, the pitch solidifying again.
It has now been shown that one can achieve the same, even better effect than with pitch with tar of any kind, even without thick tar, if one works intensively on the mixture of coal and free-for some time on a heavy pan , whereby the initially moist mixture under the pressure of the runners through the

Participate in the binding, perhaps in such a way that the coal toilet itself on the surface (like bituminous brown coal)
become capable of hindrance.
It makes no further sense. that the present process, which is usually carried out without any heating, offers economic and operational advantages over the known pitch process. The present briquettes are distinguished, which is of great importance, in that they soften less easily in the heat and stand better in the fire.
