Description

Verfahren zur Gewinnung von gleichförmig stückigem Koks Die Erfindung bezweckt die Gewinnung von gleichförmig stückigem Koks aus Steinkohle und erreicht :diesen Zweck durch ein neues Verfahren, bei welchem angemessen zerkleinerte Steinkohle unter Zusatz von Sulfitablauge und Pech oder ähnlichen, in emulgierter Form anzuwendenden bituminösen IB;indemitteln brikettiert und hierauf in Form der Briketts verschwelt oder verkokt wird.Method of Obtaining Uniform Lump Coke The invention aims at the production of uniformly lumpy coke from hard coal and achieved : this purpose through a new process in which appropriately crushed hard coal with the addition of sulphite liquor and pitch or similar, to be used in emulsified form bituminous IB; briquetted by means and then carbonized in the form of briquettes or is coked.

In älteren Patentschriften (q.71 358 und 491 21o) ist die Verkokung von Steinkohle beschrieben worden, welche zuvor unter Zusatz von wasserlöslichen organischen Bindemitteln, z. B. Sulfitablauge, Zellpech, Melasse u. dgl., oder von anorganischen, in Wasser aufschlämmbaren Bindemitteln, z. B. Ton, Zement u. dgl., oder von emulsionsartigen Gemischen der vorgenannten Bindemittelarten brikettiert wird. Durch diese bekannten Vorschriften sollten Pech oder ähnliche organische Bindemittel grundsätzlich ausgeschlossen sein. Der Fachmann mußte also annehmen, daß Mischungen oder Emulsionen von Sulfitablauge und Pech oder ähnlichen organischen Bindemitteln für den vorliegenden Zweck unbrauchbar sind.In older patents (q.71 358 and 491 21o) the coking of hard coal has been described, which was previously carried out with the addition of water-soluble organic binders, e.g. B. sulphite waste liquor, cell pitch, molasses and the like., Or inorganic binders which can be suspended in water, e.g. B. clay, cement and the like., Or is briquetted from emulsion-like mixtures of the aforementioned types of binders. These known regulations should in principle exclude pitch or similar organic binders. The person skilled in the art had to assume that mixtures or emulsions of sulphite waste liquor and pitch or similar organic binders are unsuitable for the present purpose.

Das Gemisch der zu brikettierenden Steinkohle und der bituminösen Bindemittel wird erfindungsgemäß bei höheren Drücken, d. h. bei mindestens 750 kg/cm2 verpreßt und hierauf beispielsweise in einem stehenden Schacht mittels inerter Spülgase verschwelt oder auch in einem außenbeheizten Ofen mit schmalen Kammern verkokt. In jedem Fall wird nach dem angegebenen Verfahren ein gleichförmig stückiger, druck-, Sturz- und abriebfester Koks gewonnen.The mixture of the coal to be briquetted and the bituminous binder is compressed according to the invention at higher pressures, ie at least 750 kg / cm2 and then carbonized in a standing shaft using inert purging gases or coked in an externally heated furnace with narrow chambers. In any case, a uniformly lumpy, pressure-resistant, fall-resistant and abrasion-resistant coke is obtained by the specified process.
