Description

Verfahren zum Verkoken gasreicher Kohle Es ist bekannt, daß die Erzeugung eines festen Kokses aus gasreicher schlechtbackender Kohle durch den Zusatz von Pech gefördert wird. Es ist weiterhin bekannt, da13 man den im Kokereigas enthaltenen Teer weitgehend dadurch in Pech umwandeln kann, daß man ihn mit Sauerstoff, beispielsweise mit Luft, gegebenenfalls unter Zusatz vo:n Schwefelsäume zum Teer, verbläst. Es ist ferner bekannt, daß die bei der Entgasung anfallende Teermenge bei einer Mitteltemperaturverkokung oder -schwelung höher isst als bei der Hochtemperaturverkokung. Es ist auch bekannt, Schwelkoks der zu verkokenden Kohle zuzusetzen.Process for coking gas-rich coal It is known that the production of a solid coke from gas-rich, poorly baked coal by the addition of Bad luck is encouraged. It is also known that the gas contained in the coke oven gas can be used Tar can largely be converted into pitch by mixing it with oxygen, for example with air, if necessary with the addition of sulfur fringes to the tar. It it is also known that the amount of tar resulting from degassing occurs in the case of medium-temperature coking or simmering eats higher than with high-temperature coking. It is also known Adding coke to the coal to be coked.

Gemäß d:er. Erfindung wird die Verkokung gasreicher Kohle in folgender Weise vorgenommen Ein Teil der Kohle wird bei niederer oder mittlerer Temperatur entgast. Aus den entstehenden Gasen wird der Teer gewonnen und weitgehend zu Pech verblasen, das erhaltene Pech wird fein gemahlen und einer solchen an sich möglichst großen Menge Feinkohle beigegeben, daß die Mischung bei der Hochtemperaturverkokung einen festen Koks- ergibt. Der bei der Schwelung bzw. Mitteltemperaturverkokung in kleinen Stükken bzw. in Pulverform anfallende Koks kann nach entsprechender Feinmahlung ebenfalls der Mischung von Feinkohle und Pech beigegeben werden.According to the. Invention is the coking of gas-rich coal in the following A part of the coal is made at low or medium temperature degassed. The tar is extracted from the gases produced and largely turned into pitch blow, the pitch obtained is finely ground and such as possible large amount of fine coal added that the mixture in the high temperature coking gives a solid coke. The one in the smoldering or medium-temperature coking Coke obtained in small pieces or in powder form can be refined after appropriate fine grinding can also be added to the mixture of fine coal and pitch.

Je nach der Art der Kohle kann :es zweckmäßig sein, die Mischung von Feinkohle mit Pech und gegebenenfalls Schwelkoks vor der Verkokung zu Kohlekuchen zu verdichten odesr zu Briketten zu verformen.Depending on the type of coal: it may be appropriate to mix Fine coal with pitch and, if necessary, low-temperature coke before coking to form coal cake to compress or to deform into briquettes.
