Description

Verfahren zum Verkoken von flüssigen Kohlenwasserstoffen Die Erfindung betrifft ein Verfahren zum Verkoken von flüssigen Kohlenwasserstoffen, wie Öle, Teere, Peche, welches darin besteht, daß man den Kohlenwasserstoff in geringen Mengen in einer geschlossenen Kammer auf eine im wesentlichen horizontale Fläche aufbringt, die von außen auf eine Verkokungstemperatur erhitzt wird, und daß man dieses Aufbringen des Kohlenwasserstoffs auf den bereits gebildeten Koks fortsetzt, bis sich eine feste Schicht aus metallurgischem Koks von wesentlicher Dicke auf der erhitzten Fläche aufgebaut hat.Method of coking liquid hydrocarbons The invention relates to a process for coking liquid hydrocarbons such as oils, Tar, pitch, which consists in the fact that the hydrocarbon in small quantities in a closed chamber on a substantially horizontal surface, which is heated externally to a coking temperature, and that this application of the hydrocarbon on the already formed coke continues until a solid layer of metallurgical coke of substantial thickness on the heated Has built up area.

Der Vorteil, den man durch diese Erfindung erzielt, besteht darin, daß man aus einem flüssigen Kohlenwasserstoff metallurgischen Koks erhalten kann.The advantage achieved by this invention is that that metallurgical coke can be obtained from a liquid hydrocarbon.

Unter metallurgischem Koks ist bekanntlich ein Koks zu verstehen, der eine Struktur besitzt, die ihn zur Verwendung in Kupolöfen, Hochöfen u. dgl. geeignet macht. Ein metallurgischer Koks muß folgende Eigenschaften haben: t. Er muß stark genug sein- um seiner Behandlung und Beschickung standhalten zu können, ohne wesentlich zu zerbrechen.As is well known, metallurgical coke is understood to mean a coke, which has a structure that makes it suitable for use in cupolas, blast furnaces, and the like. makes suitable. A metallurgical coke must have the following properties: t. He must be strong enough - to withstand its handling and loading, without breaking significantly.

2. Er muß das Gewicht des Roheisens im Kupolofen oder das Gewicht des Eisens und des Flußmittels im Kupolofen aushalten können, ohne zerquetscht zu werden.2. It must be the weight of the cast iron in the cupola, or the weight of iron and flux in the cupola without being crushed will.

3. Er muß in Klumpen oder Stücken von erheblicher Größe gewonnen werden, um den Kupolofen oder Hochofen nicht zu ersticken.3. It must be obtained in lumps or pieces of considerable size, so as not to suffocate the cupola or blast furnace.

Der gewöhnliche Petroleumkoks ist weich und deshalb zerbrechlich, woraus sich ergibt, daß er bei der Behandlung zerbricht. Metallurgischer Koks ist bisher als Handelsprodukt nie aus einem flüssigen Kohlenwasserstoff hergestellt worden, obgleich es möglich gewesen wäre, einen solchen Koks zu erhalten, wenn man Pech einer geeigneten Wärmebehandlung unterwerfen würde. Ein solches Verfahren ist aber unrentabel. Das den Gegenstand der Erfindung bildende Verfahren ist dagegen technisch leicht durchzuführen und in kaufmännischem Sinne sehr rentabel, und man erhält ein Produkt von hohem Handelswert.Ordinary petroleum coke is soft and therefore fragile, from which it follows that it breaks during treatment. Metallurgical coke is never made from a liquid hydrocarbon as a commercial product although it would have been possible to get such a coke if one Would subject pitch to a suitable heat treatment. One such procedure is but unprofitable. The method forming the subject of the invention is against it technically easy to carry out and very profitable in a commercial sense, and you receives a product of high commercial value.

PATENTANSPRUCH: Verfahren zum Verkoken von flüssigen Kohlenwasserstoffen, wie Öle, Teere, Peche, dadurch gekennzeichnet, daß der Kohlenwasserstoff in geringen Mengen in einer geschlossenen Kammer auf eine im wesentlichen horizontale Fläche aufgebracht wird, die von außen auf eine Verkokungstemperatur erhitzt wird, und daß dieses Aufbringen des Kohlenwasserstoffes auf den bereits gebildeten Koks fortgesetzt wird, bis sich eine feste Schicht aus metallurgischem Koks von wesentlicher Dicke auf der erhitzten Fläche aufgebaut hat. Claim: Process for coking liquid hydrocarbons, such as oils, tars, pitches, characterized in that the hydrocarbon is applied in small quantities in a closed chamber to an essentially horizontal surface which is heated externally to a coking temperature, and that this is Application of the hydrocarbon to the coke already formed is continued until a solid layer of metallurgical coke of substantial thickness has built up on the heated surface.
