Description

Verfahren zur spaltenden Druckhydrierung von hochsiedenden Kohledestillaten, Teerölen u. dgl. Bei der spaltenden Druckhydrierung hochsiedender Kohledestillate haben bereits wasserstoffanlagernde Metalle als Katalysatoren Verwendung gefunden. Diesen Katalysatoaen haftet jedoch der Nachteil an, daß ihre Spaltwirkung nicht genügend ist. Es wurde nun gefunden, daß die Wirkung solcher Metalle erheblich gesteigert wird, wenn man ihnen solche Halogenide zufügt, die bei der argewendeten Hydriertemperatur von 4oo bis 55o° bereits einen erheblichen Dampfdruck zeigen, z. B. :die Halogenzde des Quecksilbers oder Zinns. Derartige Halogenide treten mit dem Ausgangsgut in besonders innige Berührung und sind infolgedessen bereits in geringen Mengen wirksam.Process for the splitting pressure hydrogenation of high-boiling coal distillates, Tar oils and the like in the cracking pressure hydrogenation of high-boiling coal distillates have already found use of hydrogen-attaching metals as catalysts. However, these catalysts have the disadvantage that their cleavage effect is not is sufficient. It has now been found that the effect of such metals is increased considerably if such halides are added to them, the hydrogenation temperature used from 4oo to 55o ° already show a considerable vapor pressure, e.g. B.: the halogen plate of mercury or tin. Such halides enter with the starting material particularly intimate contact and are therefore effective even in small amounts.

Bei der Ausführung des Verfahrens können außerdem noch indifferente Stoffe, wie Kiesel -gur oder Kohle, verwendet werden. Beispiel i Erhitzt man Rohnaphthalin in Gegenwart von fein verteiltem Eisen und 2% Zinnbromid unter einem Wasserstoffanfangsdruck von 8o at auf 450 bis 500°, so erhält man durch Destillation des Rohpro-dukfies etwa 5o0,1o bis Co' siedende Kohlenwasserstoffe, welche vorwiegend aus Benzol und seinen Homologen bestehen.In the execution of the procedure, indifferent Substances such as kieselguhr or coal can be used. Example i If crude naphthalene is heated in the presence of finely divided iron and 2% tin bromide under an initial hydrogen pressure from 80 at to 450 to 500 °, this is obtained by distilling the raw product about 5o0.1o to Co 'boiling hydrocarbons, which mainly consist of benzene and consist of its homologues.

Arbeitet man dagegen in Abwesenheit des Halogenids unter sonst,gleichen Bedingungen, so erhält man nur 25 bis 30% bei i8o° siedende Koblenwassersfioffe.If, on the other hand, one works in the absence of the halide under otherwise identical conditions Conditions, one obtains only 25 to 30% of the hydrocarbons boiling at 180 °.

Beim Ersatz des Zinnbromids durch die gleiche Menge Eisen-, Chrom- :oder Magnesiumchlori:d, an sich bekannten Katalysatoren für :die spaltende Druckhydrierung, geht andererseits die Ausbeute an unterhalb i8o° siedenden Stoffen auf 30% und weniger zurück. Beispiel 2 Wird Anthracenöl (oberhalb 3oo° siedend) in Gegenwart von Kupferdnehspänen und j% Antimontribromid bzw. Wismuttrichlorid unter 8o bis goat Wasserstoffanfangsdruck auf 450 bis 5oo° erhitzt, so lassen sich aus dem Reaktionsprodukt durch Destillation 400'o bis 22o° siedende Benzolkohlenwasserstofre abtrennen, wähnend der Destillationsrückstand erneut der Druckwärmebehandlung unterworfen werden kann.When replacing the tin bromide with the same amount of iron, chromium : or Magnesium Chlori: d, known catalysts for: the splitting pressure hydrogenation, on the other hand, the yield of substances boiling below 180 ° goes to 30% and less return. Example 2 Is anthracene oil (boiling above 300 °) in the presence of copper filings and 1% antimony tribromide or bismuth trichloride under 80 to 100% initial hydrogen pressure heated to 450-5oo °, so can be from the reaction product by distillation Separate 400'o to 22o ° boiling benzene hydrocarbons, while the distillation residue can be subjected to the pressure heat treatment again.

Die Verwendung - von aus Metallen der sechsten Gruppe des periodischen Systems und Halogeniden bestehenden Katalysatoren soll hier, soweit sie durch das Patent 654024 geschützt ist, ausgenommen sein.The use - of made of metals of the sixth group of the periodic System and halides existing catalysts should here, as far as they are by the Patent 654024 is protected, be excluded.
