Description

Verfahren zur Spaltung von Kohlenwasserstoffölen oder Druckhydrierung von Kohlen, Teeren oder Mineralölen . Es ist bekannt, bei der Druckhydrierung von Kohlen, Teeren oder Mineralölen oder bei der Spaltung von KohlenwasserstofF,ölen Schwermetallsulfide, insbesondere solche des Molybdäns oder Wolframs, als Katalysatoren zu verwenden.Process for splitting hydrocarbon oils or pressure hydrogenation of coals, tars or mineral oils. It is known in the pressure hydrogenation of Coals, tars or mineral oils or in the splitting of hydrocarbons, oils Heavy metal sulfides, especially those of molybdenum or tungsten, as catalysts to use.

- Es wurde gefunden, daß sich die erwähnten Reaktionen besonders vorteilhaft, insbesondere unter Erzielung. guter Ausbeuten, ausführen lassen, wenn der Katalysator aus einer Lösung von Molybdän- oder Wolframsulfid oder den entsprechenden Oxyden in mit Wasserstoff gesättigten, ' stickstoffhaltigen cyclisch-en Kohlenstoffverbindungen, die zweckmäßig Wasser enthalten, durch Behandeln mit Schwefelwasserstoff und Zersetzung der ausgefällten zum Sulfid hergestellt ist: Als stickstoffhaltige gesättigte cyclische Kohlenstoffverbindiw.gen kommen z. B. Piperidin, Pip:erazin oder Cyclohexylamin in Betracht. Letzteres kamlnt in erster Linie zur Lösung von Wolframsulfid oder Wolframoxyd in Frage.- It has been found that the reactions mentioned are particularly advantageous, especially while achieving. good yields, run if the catalyst from a solution of molybdenum or tungsten sulfide or the corresponding oxides in hydrogen-saturated, nitrogen-containing cyclic carbon compounds, which suitably contain water, by treatment with hydrogen sulfide and decomposition the precipitated is produced to the sulfide: As nitrogen-containing saturated cyclic Carbon compounds come e.g. B. piperidine, pip: erazine or cyclohexylamine into consideration. The latter is primarily used to dissolve tungsten sulfide or Tungsten oxide in question.

Zur Herstellung des Katalysators wird seine der genariuten Schwermetallverbindtmgen in einem der @erwähnten Lösungsmittel gelöst, wobei etwa 50% bis etwa, goo/o Wasser zugegen sein können. In die Lösung leitet man alsdann bei etwa 4o bis r oo°, zweckmäßig- bei 6o bis 8o°, Schwefelwasserstoff ein, wobei sich eine organische Verbindung enthaltende Komplexverbindung abscheidet. Diese wird abgetrennt und mit verdünnter Säure, z. B. . 2- bis 4%iger Salzsäure, oder durch Erhitzen in einem indifferenten Gas oder in Wassexgtoff zersetzt, wobei ein reines Metallsulfid übrigbleibt, das als Katalysator hervorragende Wirksamkeit zeigt.To manufacture the catalytic converter, its heavy metal compounds are used dissolved in one of the @ mentioned solvents, with about 50% to about, goo / o water can be present. One then passes into the solution at about 4o to r oo °, expediently at 6o to 8o °, hydrogen sulfide, containing an organic compound Complex compound separates. This is separated off and treated with dilute acid, e.g. B. 2 to 4% hydrochloric acid, or by heating in an indifferent Gas or decomposed in Wassexgtoff, leaving a pure metal sulfide that shows excellent activity as a catalyst.

Beispiel Molybdäntrioxyd wird in einer io%igen wässerigen Pip!eridinlösung bei 5o bis 6o° gelöst. In die filtrierte und abgekühlte Lösung wird 48 Stunden lang Schwefelwasserstoff eingeleitet, wobei dunkelrote Kristalle des Pipieridinsulfosalzes ausfallen. Durch Zersetzen des Komplexsalzes mit kalter q.%igiär Salzsäure erhält man Molybdänsulfit. Dieses wird säurefrei ge'was'chen, an der Luft getrocknet amd geformt. Über diesen Kataly-Bator werden die Dämpfe reines von i8o bis 325° siedenden Erdölgasöls zusammen mit Wasserstoff bei 325° und unter !einem Druck von 2oo.at mit einem Durchsatz von 2 bis 2; 5'kg Gasöl/Std./1 Katalysatorraii!m geleitet. Man erhält ,ein Produkt mit 65 bis 7o% Benzin (bis 18o° siedend), das etwa 36% bis ioo° siedende Anteile enthält. Die Ausbeute beträgt 95%.Example Molybdenum trioxide is dissolved in a 10% aqueous solution of piperidine solved at 5o to 6o °. In the filtered and cooled solution is 48 hours Hydrogen sulfide introduced, with dark red crystals of the Pipieridinsulfosalzes fail. Obtained by decomposing the complex salt with cold q.% Hydrochloric acid one molybdenum sulfite. This is washed acid-free, air-dried and shaped. Via this catalyst the vapors become pure, boiling from 80 to 325 ° Petroleum gas oil together with hydrogen at 325 ° and under a pressure of 2oo.at with a throughput of 2 to 2; 5 kg gas oil / hour / 1 catalyst room. Man receives a product with 65 to 7o% gasoline (boiling up to 18o °), which is about 36% to 100 ° Contains boiling components. The yield is 95%.
