Description

Verfahren zur Herstellung insbesondere niedrigsiedender Kohlenwasserstoffe aus Kohlearten, Teeren, Mineralölen u. dgl. Es ist bekannt, aus Kohlearten, Teeren, Mineralölen u. dgl. wertvolle, insbesondere niedrigsiedende Kohlenwasserstoffe durch spaltende Druckhydrierung in mehreren Stufen zu gewinnen.Process for the production of, in particular, low-boiling hydrocarbons from coal types, tars, mineral oils and the like. It is known that from coal types, tars, Mineral oils and the like. Valuable, especially low-boiling hydrocarbons to gain splitting pressure hydrogenation in several stages.

Es wurde nun gefunden, daß es bei der Durchführung der Druckhydrierung in mehreren Stufen sehr vorteilhaft ist, in der zweiten Stufe bzw. den folgenden Stufen des Verfahrens nach Abtrennung der in der ersten Stufe gebildeten niedriger siedenden Produkte eine höhere Temperatur zugleich mit einer erheblichen Druckerhöhung oder mit einer Erhöhung des Wasserstoffpartialdrukkes in der oder den nachfolgenden Stufen anzuwenden.It has now been found that when carrying out the pressure hydrogenation is very advantageous in several stages, in the second stage or the following Stages of the process after separation of those formed in the first stage lower boiling products a higher temperature at the same time with a considerable increase in pressure or with an increase in the hydrogen partial pressure in the subsequent one or more Apply levels.

Es ist durch diese Änderungen der Arbeitsweise in den Folgestufen möglich, die noch nicht oder noch nicht wesentlich veredelten Anteile ihrer Natur nach individueller zu behandeln und die Bedingungen der Folgestufe -so zu wählen, daß eine möglichst weitgehende Veredelung bzw. Weiterveredelung in der Folgestufe gewährleistet wird.It is through these changes in the way of working in the subsequent stages possible, the parts of their nature that have not yet been or not yet significantly refined to be treated more individually and to choose the conditions of the next stage - so, that the greatest possible refinement or further refinement in the next stage is guaranteed.

Es ist zwar schon bekännt, bei der Druckhydrierung den bei der Reaktion verbrauchten Wasserstoff in der nächsten. Behandlimgsstufe durch Frischgas zu ersetzen. Hierbei handelt es sich jedoch nicht um eine Steigerung des Wasserstoffpartialdruckes gegenüber der ersten Stufe. Man hat ferner auch schon vorgeschlagen, bei der Kohleverflüssigung die hochsiedenden Anteile der Produkte wieder in den Ofen zurückzuführen, und zwar an einer Stelle, wo die Verflüssigung schon fortgeschritten ist. Da die zweite Behandlung hierbei jedoch unter geringerem Wasserstoffpartia'ldruck ausgeführt wird, liegt hier eine Verschärfung der Reaktionsbedingungen, wie angegeben, nicht vor. Fernerhin ist auch schon die mehrmalige Behandlung der schwer spaltbaren Bestandteile unter geeignet ausgewählten Temperaturen beschrieben. Es ist jedoch nichts davon erwähnt, daß in der zweiten bzw. in den folgenden Stufen die Arbeitsbedingungen gegenüber der vorausgehenden Stufe in der angegebenen Weise verschärft werden sollen.It is already known that in the case of pressure hydrogenation that in the reaction consumed hydrogen in the next. Replace the treatment stage with fresh gas. However, this is not an increase in the hydrogen partial pressure compared to the first stage. It has also already been proposed for coal liquefaction to return the high-boiling components of the products to the furnace, namely at a point where liquefaction has already progressed. Because the second treatment here, however, is carried out under a lower partial pressure of hydrogen here a tightening of the reaction conditions, as indicated, does not exist. Furthermore is also the repeated treatment of the difficult to split components under suitably selected temperatures described. However, none of this is mentioned that in the second or in the following stages the working conditions opposite the previous stage should be tightened in the manner indicated.

Beispiel Ein schweres amerikanisches Rückstandsöl, das praktisch keine unter 350° siedenden Anteile enthält, wird bei Zoo at und etwa q.50° ih Gegenwart eines molybdänzinkhaltigen Katalysators mit Wasserstoff behandelt. Dabei werden mit hohem Durchsatz etwa 6o des eingebrachten Öls in Benzin und Mittelöl übergeführt, die dampfförmig zusammen mit dem Gas kontinuierlich abgezogen werden. Der verbleibende Rest, der sehr hochsiedend und asphaltreich ist; wird in einem zwei- ten Ofen bei iooo at Druck und q.6o° in Gegenwart eines molybdänchrommarrg@n haltigen Katalysators der Einwirkun Wasserstoff unterworfen. Dabei erh' ebenfalls mit hohem Durchsatz ein von dem praktisch 9o % bis 3So° sie e x= Würde man das gesamte Produkt einei@ Stufe bei gleichbleibendem Druck behandeln, so würden sich die hochmolekularen asphalt- reichen Produkte anreichern, so daß , die Durchsatzgeschwindigkeiten wesentlich herab- gesetzt werden müßten. Example A heavy American residual oil, which contains practically no components boiling below 350 °, is treated with hydrogen at Zoo at and about 50 ° in the presence of a molybdenum zinc-containing catalyst. With a high throughput, about 60 of the introduced oil is converted into gasoline and medium oil, which are continuously withdrawn in vapor form together with the gas. The remainder, the very high boiling point and is rich in asphalt; will be in a two- th oven at iooo at pressure and q.6o ° in the presence of a molybdenum chrome arrg @ n containing catalyst of the action Subject to hydrogen. In doing so, also with high throughput from which practically 9o% to 3So ° they ex = If the entire product were to be Treat stage with constant pressure, this is how the high-molecular asphalt rich products enrich so that that Throughput speeds significantly would have to be set.
