Description

Verfahren zum Spalten hochsiedender Kohlenwasserstofföle in niedriger siedende Es wurde gefunden, @däß man aus hochsiedenden Kohlenwasserstoffölen, wie Teeren, Mineralölen, deren hodhsiedenden Destillations- oder Hydrierungsprodukten, durch Spalten hohe Ausbeuten an niedrigsiedenden Kohlemvasserstoffen erhält, wenn man. als Katalysatoren Vanadin, Chrom, Molybdän, Wolfram oder Mangan in fein verteilter Form verwendet und,dem -Spaltgut bei höherer Temperatur..geringe Mengen organischer Halogenverbindungen oder Ammoniurnchlorid zusetzt. Gegenüber der bekannten urimittelbaren Verwendung von Halogenwasserstoff hat die neue Arbeitsweise den Vorteil, daß unerwünschte Polymerisationen und Schädigungen der Apparatur vermieden werden; außerdem läßt sich die Menge des während der Reaktion sich bildenden freien Halogenwasserstoffs leichter bemessen.Process for splitting high-boiling hydrocarbon oils into lower ones boiling It has been found that high-boiling hydrocarbon oils such as Tars, mineral oils, their high-boiling distillation or hydrogenation products, high yields of low-boiling coal hydrocarbons obtained by cleavage, if man as catalysts vanadium, chromium, molybdenum, tungsten or manganese in finely divided form Form used and, the split material at higher temperatures .. small amounts of organic Halogen compounds or ammonium chloride are added. Compared to the well-known primordial Use of hydrogen halide, the new procedure has the advantage that it is undesirable Polymerizations and damage to the equipment are avoided; also lets the amount of free hydrogen halide formed during the reaction more easily dimensioned.

Unter Umständen können an Stelle der Metalle auch ihre Verbindungen, insbesondere ihre .Oxyde, verwendet werden. Man kann die Metalle oder ihre Verbindungen auch auf Träger, wie Grude, aktive Kieselsäure, und ähnlichen Stoffen, niederschlagen. Der Katalysator wird vorteilhaft in geringer Menge, z. B. solchen von. o,o5 bis 5°/p, angewandt und fortlaufend mit dem zu behandelnden Gut durch die Reaktionszone geleitet. Von organischen Halogenverbindungen kommen beispielsweise Chloroform, Jodoform, Bromoform, Tetrachlorkohlenstoff, die Chlor-, Brom- oder Jodverbindungen von Benzol srnwie Methylen- oder Äthylenhalogenide in Betracht; außerdem ist Aminoniumchlorid als Zusatz geeignet. Die Halogenverbindung wird zweckmäßig in einer Menge von o,05 bis A0 oder mehr angewandt.Under certain circumstances, instead of the metals, their compounds, in particular their oxides are used. One can use the metals or their compounds also precipitate on carriers such as grude, active silica, and similar substances. The catalyst is advantageously used in a small amount, e.g. B. those of. o, o5 to 5 ° / p, applied and continuously with the material to be treated through the reaction zone directed. Organic halogen compounds include, for example, chloroform, Iodoform, bromoform, carbon tetrachloride, the chlorine, bromine or iodine compounds of benzene, such as methylene or ethylene halides; also is aminonium chloride suitable as an additive. The halogen compound is expediently in an amount of 0.05 applied to A0 or more.

Die Katalysatoren können vor, nach oder während der Aufheizung des Ausgangsstoffes zugegeben werden. Die Halogenverbindung wind dem zu behandelnden 01 erst bei höheren Temperaturen zugesetzt, z. B. bei einer Temperatur von 35o° oder mehr, zweckmäßig über 4oo°. Es wird .durch diese Maßnahme ein höherer Durchsatz durch die Apparatur erzielt. Die Reaktion kann auch in Gegenwart von Gasen, wie Wasserstoff oder Wasserdampf, ausgeführt werden. Man arbeitet bei Temperaturen von 3oo bis 700°, vorteilhaft 35o bis 5oo°.The catalysts can be added before, after or during the heating of the starting material. The halogen compound added to the wind to be treated 01 at higher temperatures such. B. at a temperature of 35o ° or more, expediently above 4oo °. This measure achieves a higher throughput through the apparatus. The reaction can also be carried out in the presence of gases such as hydrogen or water vapor. The process is carried out at temperatures from 300 to 700 °, advantageously from 35o to 500 °.

Beispiel -Gemahlene Grude wird mit einer Mangansulfatlösung getränkt und im Wasserstoffstrom auf 95o° erhitzt, wodurch die Manganverhinidung zu metallischem Mangan reduziert wird. Der so hergestellte Katalysator wird in feinverteiltem Zustand in einer Menge von -i°Io ,einem getoppten Rohöl mit einem spez. Gewicht 0,g35, das 6% bis 325° siedende Anteile enthält, zugegeben. Das '@ wird .unter einem Druck von 30 at in Rohr. " auf q.50° aufgeheizt und anschließend in Reaktionsgefäß von weiterem Durchmesser'y# als die Heizrohre geleitet. Vor Eintritt in ,das Reaktionsgefäß wird .dem 01 o,i°/o Tetrachlorkohlenstoff zugegeben. Die Produkte werden dann unter einem Druck von 5 at in einen Abscheider geleitet, in dem, sich 26°/0 von dem gesamten kondensierbaren Reaktionsprodukt 'in Form eines hochsiedenden Öles abscheiden, das als Heizöl verwendbar ist. Die in einer Menge von 7q.°/0 dampfförmig abziehenden Produkte werden frak- tioniert kondensiert. Man erhält 32'1, Benzin und q.2°4 Mittelöl, das als Gasöl verwendet oder zusammen mit Frischprodukt der Spal- 4#bng;, wieder zugeführt werden kann. Example -Ground ground is impregnated with a manganese sulphate solution and heated to 95o ° in a hydrogen stream, which reduces the manganese prevention to metallic manganese. The catalyst prepared in this way is finely divided in an amount of -i ° Io, a topped crude oil with a spec. Weight 0.g35 that is 6 % to 325 ° Contains boiling fractions, added. That '@ is in the pipe under a pressure of 30 at. " heated to q.50 ° and then in Reaction vessel of wider diameter 'y # as the heating pipes passed. Before entering the reaction vessel is .dem added 01 o i ° / o carbon tetrachloride. The products are then passed under a pressure of 5 atm into a separator in which '26% of the total condensable reaction product' is separated out in the form of a high-boiling oil that can be used as heating oil. The products withdrawn in vapor form in an amount of 7q. tioned condensed. You get 32'1, gasoline and q.2 ° 4 medium oil that is used as gas oil or together with fresh products from the Spal 4 # bng ;, can be fed back.
