Description

Verfahren zur Herstellung von gasförmigen ungesättigten und von aromatischen Kohlenwasserstoffen Das Patent 840 237 betrifft ein Verfahren zur Herstellung "asfi')riiii;#er ungesättigter Kohlenwasserstoffe, insbesondere von Äthylen, und von aromatischeri KohlenNvasserstoffen aus vorwiegend paraffinischen Kohlenwasserstoffölen oder deren Fraktionen, wobei man die Ausgangsstoffe mit porösen, inerten Stoffen in feinverteilter oder stückiger Form bei Temperaturen oberhalb 5oo bis etwa 700' und einer Durchsatzgeschwindigkeit von o,6 bis etwa 3, zweckni#ißig bis etwa 1,5 Raumteilen Aiu#gangsstoff je Raumteil Reaktionsraurn und Stunde in Berührung bringt.Process for the production of gaseous unsaturated and aromatic hydrocarbons The patent 840 237 relates to a process for the production of "asfi ') riiii; #er unsaturated hydrocarbons, in particular of ethylene, and of aromatic hydrocarbons from predominantly paraffinic hydrocarbon oils or their fractions, whereby the starting materials brings into contact with porous, inert substances in finely divided or lumpy form at temperatures above 500 to about 700 ' and a throughput rate of 0.6 to about 3, expediently to about 1.5 parts by volume of raw material per part of reaction space and hour.

Es hat sich nun gezeigt, daß man bei diesem Verfahren bei Verwendung poröser inerter, nicht metallischer Stoffe die Durchsatzgeschwindigkeit vorteilhaft wesentlich erhöhen kann. Sie soll erfindungsgemäß mehr als 3,5, vorteilhaft mindestens etwa -1, zweckmäßigjedoch mehr, z. B. etwa 5 bis 15 oder mehr Raumteile, Ausgangsstoff, in flüssigem Zustand gemessen, je Raumteil Reaktionsraum und Stunde betragen. Die Reaktion verläuft hier bei einer Temperatur von 5oo bis 85o', insbesondere 600 bis 800'. It has now been shown that in this process, when using porous, inert, non-metallic substances, the throughput rate can advantageously be increased significantly. According to the invention, it should be more than 3.5, advantageously at least about -1, but expediently more, e.g. B. about 5 to 15 or more parts of space, starting material, measured in the liquid state, amount to reaction space and hour per part space. The reaction here takes place at a temperature of 500 to 85o ', in particular 600 to 800'.

Als inerte Stoffe kommen z. B. Bimsstein, Bauxit, Kieselgur, Porzellankugefn, Tonscherben, Quarzstücke oder Koks in, Frage.As inert substances such. B. pumice stone, bauxite, kieselguhr, porcelain glass, Pottery shards, pieces of quartz or coke in question.

Bei Verwendung dieser Stoffe in feinverteilter oder körniger Form können sie zugleich auch als Wärmeträger dienen, indem man sie in überhitztem Zustand in den Reaktionsraum einführt.When using these substances in finely divided or granular form they can also serve as heat carriers by keeping them in an overheated state introduces into the reaction chamber.

Bei dieser Arbeitsweise werden gegenüber dein Verfahren des Hauptpatents höhere Ausbeuten an ungesättigten gasförmigen Kohlenwasserstoffen erhalten. B e i s p i e 1 Ein von --6o bis 36o' siedendes Gasöl mit einem spezifischen Gewicht von 0,850 wird bei 69o' durch einen mit Porzellanstück-en gefüllten Reaktionsraum geleitet, wobei ein Durchsatz von 5,3 Raumteilen Gasöl je Raumteil Reaktionsraum und Stunde gewählt wird. Man erhält aus ioo Teilen AusgangsstOff 35 Teile flüssige, vorwiegend aus aromatischen Kohlenwasserstoffen bestehende Anteile und #56 Teile gasförmige Kohlenwasserstoffe, die 72 0/0 Un- gesättigte Kohlenwasserstoffe enthalten.In this procedure, compared to the process of the main patent, higher yields of unsaturated gaseous hydrocarbons are obtained. B e is p ie 1 A gas oil boiling from --6o to 36o 'with a specific gravity of 0.850 is passed at 69o' through a reaction space filled with porcelain pieces, with a throughput of 5.3 parts by volume of gas oil per part of space of reaction space and hour is chosen. From 100 parts of starting material, 35 parts of liquid, predominantly aromatic hydrocarbons, and 56 parts of gaseous hydrocarbons containing 72% unsaturated hydrocarbons are obtained.
