Description

Verfahren zum Brikettieren von Steinkohlenstaub. Durch das Hauptpatent ist die Brikettierung von Steinkohlenstaub in der Weise geschützt, daß man den Staub durch Erhitzen plastisch macht, ohne daß dabei Schwelgase entweichen, und ihn in diesem Zustande heiß preßt.Process for briquetting hard coal dust. By the main patent the briquetting of coal dust is protected in such a way that one removes the dust plasticizes it by heating, without the escape of carbonization gases, and transforms it into hot pressing in this state.

Es hat sich nun als zweckmäßig erwiesen, dem Kohlenstaub einen geringen Zusatz von den üblichen Bindemitteln beizumischen und dann nach dem im Hauptpatent beschriebenen Verfahren zu brikettieren.It has now proven to be expedient to add a little to the coal dust Addition of the usual binders and then according to the main patent to briquette the procedure described.

Während bisher beispielsweise 6 bis 8 °1a Pech benötigt wurden, gelingt es auf diese Weise schon mit Zusätzen unter I °/o Pech auszukommen, ohne daß die Brikette qualitativ schlechter werden. Vor dem des Hauptpatents hat das vorliegende Verfahren noch den Vorzug, auch schon bei niedrigeren Temperaturen anwendbar zu sein.While previously, for example, 6 to 8 ° 1a pitch was required, it succeeds In this way, it is possible to manage with additives below 1 / o bad luck, without the Briquette deteriorate in quality. Before that of the main patent, the present Process still has the advantage of being applicable even at lower temperatures be.

Ein weiterer Vorteil vor den bisherigen Brikettierungsverfahren liegt in der Möglichkeit, sehr harte Peche zu verwenden. Während zur Zeit von einem guten Brikettierpech ein Erweichungspunkt von 6o bis 70° verlangt wird, ist es nach vorliegendem Verfahren möglich, selbst Peche von einem Erweichungspunkt von 25o° zu verwenden. Hartes Steinkohlenpech anstatt des weichen als Bindemittel zu benutzen, ist an sich bereits vorgeschlagen, doch wird fast ausschließlich mittelweiches Steinkohlenteerpech verwendet.Another advantage over the previous briquetting process lies in the possibility of using very hard pitch. While at the time of a good Briquetting pitch a softening point of 6o to 70 ° is required, it is according to the present Process possible to use even pitches with a softening point of 25o °. Using hard coal pitch as a binder instead of the soft one is in itself already proposed, but medium-soft coal tar pitch is used almost exclusively used.
