Description

Verfahren zur Veredelung von Kohlen, Teeren, Mineralölen u. dgl.Process for refining coals, tars, mineral oils and the like.

Zusatz zum Patent 553 407 Gegenstand des Hauptpatents 533 407 der Klasse 120 ist ein Verfahren zur Veredelung von Kohlen, Teeren, Mineralölen usw., deren Destillations-undUmwandlungsprodukten sowie Rückständen u. dgl. bei höheren Temperaturen in Gegenwart von Wasserstoff, insbesondere unter Druck, wobei man mindestens die mit den heißen Reaktionsstoffen in Berührung kommenden Teile der Apparatur, alle oder zum Teil aus Kupfer-Zink-Legierungen herstellt oder damit überzieht. Addition to the patent 553 407 subject of the main patent 533 407 of the Class 120 is a process for the refinement of coals, tars, mineral oils, etc., their distillation and conversion products as well as residues and the like at higher Temperatures in the presence of hydrogen, especially under pressure, with at least the parts of the apparatus that come into contact with the hot reactants, all or some of them are made from or coated with copper-zinc alloys.

Es wurde nun gefunden, daß man bei den erwähnten Verfahren mit Vorteil auch Zinklegierungen mit einem über 500° liegenden Schmelzpunkt verwenden kann, bei denen das Kupfer durch Metalle der Eisengruppe ersetzt ist. Besonders geeignet sind beispielsweise Legierungen, wie-Eisen-Zink, Nickel-Zink, Eisen-Nickel-Zink. Man kann auch niedriglegierte, nicht schwefelbeständige Stähle mit einem Zusatz von Zink versehen, wodurch ihre Korrosionsfestigkeit gegen Wasserstoff unter Druck sowie gegen Schwefelwasserstoff und Kohlenoxyd überraschenderweise bedeutend erhöht wird. Es ist zweckmäßig, diese Legierungen unter Druck zu erschmelzen. Es hat sich gezeigt, daß diese Materialien gegen Wasserstoff und Kohlenoxyd auch unter hohen Drucken beständig sind. Selbst wenn Schwefelwasserstoff zugegen ist und sein Partialdruck in den Reaktionsgasen mehrere Atmosphären beträgt, findet auch nach längerem Gebrauch kein nennenswerter Angriff durch Schwefel statt. Die beanspruchten Metallegierungen haben sich bei der Druckhydrierung von Kohlearten, Teeren, Mineralölen u. dgl. als Katalysatoren günstig erwiesen, insbesondere dann, wenn die Wasserstoffkonzentration der Menge des in den Ausgangsstoffen enthaltenen Schwefels derart angepaßt wird, daß bei hohem Schwefelgehalt der Ausgangsstoffe auch die Wasserstoffkonzentration höher gewählt wird. It has now been found that the processes mentioned are advantageous can also use zinc alloys with a melting point above 500 °, in which the copper is replaced by metals of the iron group. Particularly suitable are for example alloys such as iron-zinc, nickel-zinc, iron-nickel-zinc. You can also use low-alloy, non-sulfur-resistant steels with an additive provided by zinc, increasing their corrosion resistance to hydrogen under pressure and surprisingly significantly increased against hydrogen sulfide and carbon oxide will. It is advisable to melt these alloys under pressure. It has showed that these materials against hydrogen and carbon oxide even under high Printing are resistant. Even if hydrogen sulfide is present and its partial pressure several atmospheres in the reaction gases occurs even after prolonged use no significant attack by sulfur took place. The claimed metal alloys have proven themselves in the pressure hydrogenation of types of coal, tars, mineral oils and the like Catalysts proved beneficial, especially when the hydrogen concentration the amount of sulfur contained in the raw materials is adjusted in such a way, that with a high sulfur content of the starting materials also the hydrogen concentration is chosen higher.

Beispiel I Ein amerikanisches Heizöl mit I, 8 O/o Schwefel wird bei 480" mit Wasserstoff unter 200 at Druck in Gegenwart eines aus Wolframsäure und Zink hergestellten Katalysators in einem Hochdruckofen behandelt. Example I An American heating oil with 1.8% sulfur is used at 480 "with hydrogen under 200 at pressure in the presence of one of tungstic acid and Zinc-made catalyst treated in a high pressure furnace.

Die mit den heißen Reaktionsstoffen in Berührung kommenden Teile werden mit einem aus 50 % Nickel und 50 O/o Zink bestehenden Futter ausgekleidet. Auch-nach langer Betriebsdauer ist kein nennenswerter Angriff des Materials zu erkennen.Those in contact with the hot reactants coming Parts are lined with a lining consisting of 50% nickel and 50% zinc. Even after a long period of operation, no noticeable attack on the material can be seen.

Beispiel 2 Ein Rohöl mit 3 01o Schwefelgehalt wird bei 450° mit Wasserstoff unter 200 at Druck in einem Hochdruckgefäß, das mit einem aus 15% Zink und 85% Eisen bestehenden Futter versehen ist, behandelt. Nach langer Betriebsdauer zeigt das Material noch keine Veränderung. Example 2 A crude oil with a sulfur content of 30 ° is mixed with hydrogen at 450 ° under 200 at pressure in a high pressure vessel made from 15% zinc and 85% iron existing lining is treated. This shows after a long period of operation Material no change yet.
