Description
Verfahren zur Herstellung von Kohlenwasserstoffen aus festen kohlenstoffhaltigen Stoffen Es wurde gefunden, daß man bei der Druckhydrierung fester kohlenstoffhaltiger Stoffe gute Ausbeuten an wertvollen Verflüssiggngsproduktenerhält, wenn man ,als Katalysator Calciumsulfat verwendet. Dieses wird in fein verteilter, trockener oder suspendierter Form den zu behandelnden Ausgangsstoffen zugegeben. Man kann auch in der Natur vorkommendes C,alciumsulfat verwenden. Das Calciums'ulfa.t kann auch mit anderen, z. B. als Katalysatoren für die Druckhydrierung schon vorgeschlagenen Metallverbindungen, z. B. solchen der Metalle der 6. bis B. Gruppe des periodischen Systems, verwendet werden. Als besonders vorteilhaft hat sich der Zusatz von Nickelverbindungen, wie Nickelcarboonat,erwiesen. Der Katalysator wird Aden Ausgangsstoffen in einer Mange von o, 5 bis 5 % zugesetzt. .Process for the production of hydrocarbons from solid carbonaceous Substances It has been found that pressure hydrogenation produces solid carbonaceous substances Substances obtain good yields of valuable liquefaction products if one, as Calcium sulfate catalyst used. This comes in finely divided, drier or more suspended form added to the starting materials to be treated. One can also Use naturally occurring C, alcium sulphate. The Calciums'ulfa.t can also with others, e.g. B. already proposed as catalysts for pressure hydrogenation Metal compounds, e.g. B. those of the metals of the 6th to B. group of the periodic System. The addition of nickel compounds has proven to be particularly advantageous, such as nickel carbonate. The catalyst will Aden the starting materials in a Mange of 0.5 to 5% added. .
Als feste kohlenstoffhaltige Ausgangsstoffe kommen z. B. Braunkohle, Steinkohle oder Torf in Betracht. Besonders geeignet ist das Verfahren für sauerstoffreiche Kohlten, d. h. für solche, die mindestens 2o% Sauerstoffenthalten. Die Ausgangsstoffe. können. vor .der Verwendung auf mechanische Weise oder durch Säurebehandlung von der Gaangart oder den in Säureaa löslichen Bestandteilen befreit werden. Die mit dem Katalysator versehenen festen kohlenstoffhaltigen Stoffe werden, zweckmäßig nach Vermischen mit -einem Schweröl, der Druckhydrierung bei den hierfür üblichen Temperaturen (3oo bis 6oo°) und Drucken (2o bis 5ooat und mehr) unterworfen.As solid carbonaceous starting materials come z. B. lignite, Coal or peat into consideration. The process is particularly suitable for those who are oxygen-rich Kohlten, d. H. for those that contain at least 20% oxygen. The starting materials. can. before .use by mechanical means or by acid treatment of the Gaangart or the components soluble in Acid are freed. With the solid carbonaceous substances provided with the catalyst are expedient after mixing with a heavy oil, the pressure hydrogenation with the usual for this Temperatures (3oo to 6oo °) and pressures (2o to 5ooat and more) subjected.
Der beanspruchte Katalysator stellt eine wertvolle Bereicherung der Katalysatoren auf dem Gebiet der Druckhydrierung fester kohlengtoffhaltiger Stoffe dar; er ist gut wirksam und hat -des Vorzug, daß er billig und überall leicht zugänglich ist. Beispiel Junge de'utsc'he Braunkohle mit einem Sauerstoffgehalt von 25% wird fein gemahjen, mit 5 % Calciumslulfat und o, i % Nickelcärbonat gemischt, mit einem aus derselben Kohle stammenden Schweröl im Verhältnis i : i angepastet und zusammen mit Wasserstoff unter einem Druck von Zoo at durch reinen gasbeheizten Vorwärmer geleitet. Von hier aus gelangen die Reaktions-. teilnehmer #n sein erweitertes Reaktionsgefäß, in dem eine Temperatur von q.q.o° aufrechterhalten wird. Die Koblesubstanz wird zu 99% abgebaut. Das Verflüssigungsprodukt enthält ¢% Asphalt und besitzt ein spezifisches Gewicht von o,986; @es sieden z9% bis 3z5°. Arbeitet man ohne Zusatz von Nickelcarbonat, so jerzielt man unter sonst gleichen Bedingungen ebenfalls einen Abbau von 99 Q/o und erhält ein Verflüssigungsprodukt mit q.% Asphalt; es besitzt ein spezifisches Gewicht von o,996, und es sieden z6% davon bis 3 z5°.The claimed catalyst represents a valuable addition to the catalysts in the field of pressure hydrogenation of solid carbonaceous substances; it works well and has the advantage of being cheap and easily available everywhere. Example Young German lignite with an oxygen content of 25% is finely ground, mixed with 5% calcium sulfate and 0.1% nickel carbonate, made into a paste with a heavy oil from the same coal in the ratio i: i and together with hydrogen under one pressure from Zoo at through a purely gas-fired preheater. From here get the reaction. participant #n his extended reaction vessel, in which a temperature of qqo ° is maintained. The coble substance is degraded to 99%. The liquefaction product contains [%] asphalt and has a specific gravity of 0.986; @ It boils z9% to 3z5 °. If one works without the addition of nickel carbonate, one also achieves a degradation of 99% under otherwise identical conditions and a liquefaction product with q% asphalt is obtained; it has a specific gravity of o.996, and z6% of it boils up to 3 z5 °.
