Description
Verfahren zur Druckhydrierung von mit Öl angepasteter Kohle Es wurde gefunden, daß es von Vorteil ist, bei der Druckhydrierung von mit Öl angepastItter Kohle die Temperatur im Reaktionsraum mit fortschreitender Reaktion zu erniedrigen. Man gewinnt auf diese Weise Erzeugnisse, deren Asphaltgehalt erheblich niedriger ist als bei der bisher üblichen Arbeitsweise, bei der die Temperatur im-Reaktionsraum etwa auf gleicher Höhe gehalten oder mit fortschreitender Reaktion gesteigert wurde.Process for the pressure hydrogenation of coal pasted with oil It was found that it is of advantage in the pressure hydrogenation of oil paste Coal to lower the temperature in the reaction space as the reaction progresses. In this way, products are obtained with a considerably lower asphalt content is than in the previously customary procedure in which the temperature in the reaction chamber was kept approximately at the same level or increased as the reaction progressed.
Das Verfahren wird zweckmäßig in mehreren hintereinandergeschalteten - Reaktionsgefäßen durchgeführt und dabei durch geeignete Beheizung und Kühlung dafür gesorgt, daß die Temperatur jedes einzelnen Gefäßes innerhalb des für die Druckhydrierung von Kohle üblichen Gebietes unter derjenigen des vorhergehenden Gefäßes liegt. Als Katalysatoren können die für die Druckhydrierung bekannten Stoffe verwendet werden.The process is expediently carried out in several series - Reaction vessels carried out and by means of suitable heating and cooling ensured that the temperature of each individual vessel is within the range for the Pressure hydrogenation of coal common area below that of the preceding Vessel lies. The substances known for pressure hydrogenation can be used as catalysts be used.
Beispiel In eine aus vier Öfen bestehende Druckhydrierungsanlage wird mitteldeutsche Braunkohle zusammen mit der gleichen Menge eines über 3ä5° siedenden Schweröles und einem Eisenkatalysator eingebracht und Wasserstoff unter einem Druck von Zoo at zugeführt. Mit Hilfe von Vorwärmern und Wärmeaustauschern wird die Temperatur so eingestellt, daß sie im ersten Ofen 47o° beträgt und in den folgenden Öfen allmählich bis auf eine Endtemperatur von q.50° fällt. In einem heißen Abscheider werden die aus dem vierten Ofen austretenden Erzeugnisse in gas- und - dampfförmige Stoffe einerseits und in Asche und nicht umgewandelte Kohle enthaltendes Schweröl andererseits zerlegt. Das Schweröl enthält 8 bis io % Asphalt.Example In a pressure hydrogenation plant consisting of four ovens Central German lignite together with the same amount of one boiling above 3–5 ° Heavy oil and an iron catalyst are introduced and hydrogen under pressure fed by zoo at. With the help of preheaters and heat exchangers, the temperature adjusted so that it is 47o ° in the first oven and gradually in the following ovens falls to a final temperature of q.50 °. In a hot separator, the Products emerging from the fourth furnace are converted into gaseous and vaporous substances on the one hand and containing ashes and unconverted charcoal Heavy oil, on the other hand, is broken down. The heavy oil contains 8 to 10% asphalt.
Läßt man dagegen die Temperatur von-V_ ersten bis zum vierten Ofen von q.5q.° auf'": q.7o° ansteigen, so ist der Asphaltgehalt des gewonnenen Schweröles fast doppelt so hoch, nämlich 15 bis 18 %. Wenn in allen vier Öfen eine Temperatur von q.60° eingehalten wird, zeigt das Schweröl einen Asphaltgehalt von 12 bis 13 N .If, on the other hand, the temperature of the first to the fourth kiln is allowed to rise from q.5q. ° to '": q.7o °, the asphalt content of the heavy oil obtained is almost twice as high, namely 15 to 18%. If in all four ovens a temperature of q.60 ° is maintained, the heavy oil shows an asphalt content of 12 to 13 N.
Verzichtet man darauf, beim Arbeiten unter fallenden Temperaturen den Asphaltgehalt stärker zu erniedrigen als beim Arbeiten bei gleichbleibenden oder steigenden Temperaturen, so kann man den Durchsatz um etwa 25 0% erhöhen. Verarbeitet man die dabei erhaltenen Erzeugnisse dann in einer zweiten Hydrierungsstufe in der Gasphase, so hat man gegenüber dem bekannten Zweistufenverfahren den Vorteil, daß für die Gasgliasenhy drierung eine -erhöhte Menge Ausgangsstoff zur Verfügung steht.If you do without it when working under falling temperatures to lower the asphalt content more than when working with the same or increasing temperatures, the throughput can be increased by about 25 0%. Processed one then obtained the products in a second hydrogenation stage in the Gas phase, one has the advantage over the known two-stage process that an increased amount of starting material is available for the hydrogenation of gas glases.
