Description
Verfahren zum Erzeugen von Koksbriketten unter Zusatz anorganischer Bindemittel. Zusatz zum Patent 409550. Die bei der Tieftemperaturverkokung entfallenden Halbkokse zeigen bei der Verbrennung Eigenschaften, die sehr wertvoll sind und zum Teil, wie beispielsweise in England, den Hauptanlaß für die Durchführung der Tieftemperatur-Verkokungsverfahren gebildet haben, nämlich eine rauchschwache oder rauchlose Verbrennung, eine kurze intensive Flamme, dabei aber doch eine praktisch hinreichende Entzündlichkeit. Das sehr weite Anwendungsgebiet dieser Halbkokse erfährt nun aber durch die vorwiegend kleinstückige, teilweise grusige oder staubförmige Beschaffenheit des Halbkokses eine erhebliche Beschränkung.Process for producing coke briquettes with the addition of inorganic ones Binder. Addition to patent 409550. The ones that are omitted in the case of low-temperature coking When burned, semi-cokes show properties that are very valuable Part, as for example in England, the main reason for the implementation of the cryogenic coking process have formed, namely a low-smoke or smokeless burn, a short one intense flame, but still practically sufficient flammability. That This semi-coke is now used in a very wide range of applications small, partly gritty or dusty texture of the semi-coke a significant limitation.
Es hat daher nicht an -Versuchen gefehlt, Halbkokse zu brikettieren. Man hat versucht, ohne Bindemittel bei sehr hohen Preßdrücken oder mit Teer und Pech als Bindemittel zu arbeiten; man hat ferner versucht, auch Rohkohle mit dem Halbkoks zu mischen und so die Backfähigkeit des Halbkokses zu erhöhen. Befriedigende Ergebnisse hat man mit diesen Versuchen nicht erzielen können. Alle so hergestellten Brikette leiden an dem Fehler, daß das Brikett die wertvollen -Eigenschaften des Halbkokses ganz oder teilweise verliert.There has therefore been no lack of attempts to briquette semi-coke. Attempts have been made without a binder at very high pressures or with tar and Pitch to work as a binder; Attempts have also been made to use raw coal with the Mixing semi-coke and thus increasing the baking ability of the semi-coke. Satisfactory Results could not be obtained with these experiments. All made in this way Briquette suffer from the defect that the briquette retains the valuable properties of the Semi-coke loses all or part of it.
Das Brikettieren ohne Bindemittel erfordert nämlich so hohe Preßdrücke, daß dadurdh die Entzündlichkeit verschlechtert wird, aber trotzdem gelingt es nicht, ein genügend haltbares Brikett zu gewinnen. Beim Brikettieren mit Teer und Pech als Bindemittel entsteht zunächst der Mißstand, daß von den bei der Tieftemperatur-Verkokung gewonnenen Teererzeugnissen ein großer Teil wieder zugesetzt und beim Brikettieren verbraucht werden muß. Ferner wird durch das Pech die an denn Halbkoks so geschätzte rauchlose Verbrennung mit kurzer intensiver Flamme zu einer leicht rußbildenden Verbrennung mit langer Flamme. Das Zumischen von Rohkohle führt, abgesehen davon, daß auch hier wieder die ursprüngliche Beschaffenheit des Halbkokses ungünstig verändert wird, dem Brikett einen sehr hohen Wasser- und Aschegehalt zu, durch den das Brikett sehr wesentlich verschlechtert wird. Andere Bindemittel, deren Anwendung man versucht hat. wie z. B. Sulfitablauge, haben, abgesehen davon, daß die Ergebnisse unbefriedigend waren, den weiteren Nachteil, daß sie wasserlöslich sind und infolgedessen beim Lagern der Brikette leicht zu deren -Verfall führen können.Briquetting without a binder requires such high pressures as that the flammability is worsened, but nevertheless it does not succeed to obtain a briquette that is sufficiently durable. When briquetting with tar and pitch as a binder, the problem arises that of the low-temperature coking A large part of the tar products obtained is added again and when briquetting must be consumed. Furthermore, the pitch, which is so valued at the semi-coke, is caused by the bad luck Smokeless combustion with a short, intense flame to form a slightly soot-forming one Burning with a long flame. The addition of raw coal leads, apart from that here, too, the original nature of the semi-coke changed unfavorably becomes, the briquette has a very high water and ash content, through which the briquette is deteriorated very substantially. Other binders attempted to use Has. such as B. sulphite liquor, apart from the fact that the results are unsatisfactory had the further disadvantage that they are water-soluble and, consequently, when Storing the briquette can easily lead to its deterioration.
Brikettiert man dagegen diese Halbkokse nach dem in dem Hauptpatent für Kokerei und Gaskoks vorgeschriebenen Verfahren, so gelingt es, ein Brikett zu erhalten, daß allen Ansprüchen voll genügt. Hohe Preßdrücke auszuüben ist bei diesem Verfahren durchaus unnötig und sogar schädlich, da durch das Zusammendrücken der Poren des Brennstoffes und das Austreiben der Luft aus denselben die so besonders wichtige Leichtentzündlichkeit des Brennstoffes verlorengeht.If, on the other hand, this semi-coke is briquetted according to the one in the main patent The procedure prescribed for coking and gas coke makes it possible to create a briquette received that fully meets all requirements. High pressing pressures exercise is absolutely unnecessary and even harmful with this process, because it is squeezed together the pores of the fuel and the expulsion of air from them are so special important high flammability of the fuel is lost.
