Description

Verfahren zur Herstellung von Briketten aus Feinkohle oder Anthrazitklein. Bei der Aufbereitung von Steinkohle fallen mehr oder weniger große Mengen von Feinkohle an, die, wenn die hohle backend ist. durch Verkokung nütz.bar gemacht werden können. Handelt es sich dagegen um Magerkohlen, die nicht backen, so stellt diese feine Kohle einen schwer verwendbaren Brennstoff dar, da sie auch bei vorgängiger Brikettierung einen Koks minderer Qualität ergibt. Auch die Verwertung feinkörniger Magerkohle für Brikette, die unter Verwendung von Pech hergestellt worden sind, stößt auf Schwierigkeiten, weil der Gasgehalt dieser Brikette für industrielle Zwecke zu gering ist.Process for the production of briquettes from fine coal or small anthracite. When processing hard coal, more or less large amounts of fine coal fall at that when the hollow is baking. can be made useful by coking. If, on the other hand, it is lean coals that do not bake, this is fine Coal is a fuel that is difficult to use, as it can also be briquetted beforehand results in an inferior quality coke. Also the utilization of fine-grained lean coal for briquettes made using pitch, difficulties are encountered because the gas content of this briquette is too low for industrial purposes.

Gegenstand der vorliegenden Erfindung bildet nun ein Verfahren, daß darauf ausgeht, diese Feinkohlen, welche nach den bisher bekannten Verfahren für die Industrie nur schwer dienstbar gemacht werden können, in eine Form zu bringen, in welcher sie gewissen Industrien sehr willkommen sind. Es wurde gefundcn, daß man für gewisse Industrien sehr gut brauchbare Brikette herstellen kann, wenn man diese Magerkohle nach ihrer Entgasung mit Kalkhydrat brikettiert. Es ist dabei zu bemerken, daß die Rohkohle infolge ihrer für diese Brikettierung ungünstigen physikalischen Struktur, insbesondere ihrer zuweilen mulmigen Beschaffenheit und der lettigen Beimischungen, sich mit Kalk nicht einbinden läßt. Dagegen eignet sich dieses Kohlenmaterial dann sehr gut für dieses Verfahren, wenn die hohle vor der Brikettierung entgast wird. Man verwendet zweckmäßig bei der Brikettierung die geringstmögliche @'iTassermenge, die jeweilig durch Versuche ermittelt werden kann.The present invention now forms a method that assumes this fine coals, which according to the previously known method for it is difficult to make industry serviceable, to bring it into a form in which they are very welcome in certain industries. It was found that one can produce briquettes that are very useful for certain industries if one this lean coal is briquetted with hydrated lime after it has been degassed. It's about to note that the raw coal due to its physical unfavorable for this briquetting Structure, especially its sometimes queasy nature and the Latvian admixtures, cannot be bound with lime. On the other hand, this carbon material is then suitable very good for this process if the hollow is degassed before briquetting. It is advisable to use the smallest possible amount of water when briquetting, which can be determined in each case by experiments.

Das Verfahren wird derart ausgeführt, daß die abgeschwelten Kohlen zerkleinert, in einem bestimmten Verhältnis mit Kalk gemischt und das Gemisch in üblicher Weise in Brikettierpressen verziegelt wird. Die so hergestellten Brikette, die aus ziemlich reinem Kohlenstoff und Kalk bestehen, sind für eine Reihe von Industriezweigen wertvoll, so können sie z. B. zum Aufkohlen überfrischter Eisenbäder und für sonstige Reduktionszwecke benutzt werden, auch in der Kalkstickstoffherstellung können sie an Stelle des erforderlichen, sehr reinen Kokses verwendet werden, wobei der Kal'kge'halt ohne Nachteil sehr erheblich gesteigert werden kann. Dabei bringt die innige Berührung zwischen Kohlenstoff und Kalk dem Verfahren erhebliche Vorteile. Die obere Grenze ist selbstverständlich die stöchiometrische Menze.The process is carried out in such a way that the burned off coals crushed, mixed with lime in a certain ratio and the mixture in is usually bricked in briquetting presses. The briquette produced in this way, which are made up of fairly pure carbon and lime are useful in a number of industries valuable, so they can e.g. B. for carburizing refreshed iron baths and for others Reduction purposes are used, they can also be used in calcium cyanamide production can be used in place of the required, very pure coke, whereby the lime content can be increased very considerably without any disadvantage. It brings the intimate touch between carbon and lime the process has considerable advantages. The upper limit is of course the stoichiometric quantity.
