Description
Bei der Hydrierung von Kohle unter hohem Druck und bei erhöhter Temperatur besteht die Gefahr lokaler Überhitzung, welche zu Zersetzungen und damit zu Materialverluist führt. Es hat sich gezeigt, daß Materialverluste infolge von lokaler Überhitzung vermieden werden können, wenn man die der Reaktion zu unterwerfende Kohle in mehr oder ■ weniger fein verteiltem Zustande in FormIn the hydrogenation of coal under high pressure and at elevated temperature it exists the risk of local overheating, which leads to decomposition and thus material loss leads. It has been shown that material losses due to local overheating are avoided can be if the coal to be subjected to the reaction is in a more or less finely divided state in the form
ίο einer Aufschwemmung der Behandlung unterwirft, wobei die flüssige Komponente der Aufschwemmung von einer Verbindung gebildet wird, die durch Kohlehydrierung gewonnen wurde, unter den Arbeitsbedingungen flüssig und selbst noch der Hydrierung fähig ist. Bei der Ausführung des Verfahrens in dieser Art wird durch die Flüssigkeit, in welcher die festen Kohleteilchen aufgeschwemmt sind, jede lokal entstehende größere Temperaturerhöhung abgeleitet. Es wird außerdem der Reaktionsprozeß insofern günstig beeinflußt, als die gleichzeitige Anwesenheit von Material, das isich in verschiedenen Stadien der Hydrierung befindet, einen geregelten Fortgang des Hydrierungsprozesses begünstigt. Dieses würde nicht ohne weiteres der Fall sein, wenn die der Hydrierung unterworfene Kohle zwar auch in Form einer Aufschwemmung dem Prozeß unterworfen würde, jedoch ohne Anwendung einer Flüssigkeit, welche ihrerseits den durch die Hydrierung aus der Kohle zu gewinnenden Stoffen wesensgleich ist, so daß sie an dem Hydrierungsprozeß teilzunehmen und während ' des Prozesses eine weitere Umwandlung zu erfahren vermag.ίο subject to a suspension of treatment, wherein the liquid component of the suspension is formed by a compound obtained by carbohydrate hydrogenation became liquid under the working conditions and still capable of hydrogenation is. When performing the procedure in this manner, the liquid in which the solid coal particles are suspended, each locally arising larger Derived temperature increase. In addition, the reaction process is favorably influenced insofar as the simultaneous presence of material that is in different stages of hydrogenation, a controlled progress of the hydrogenation process favored. This would not readily be the case with hydrogenation subjected coal to the process in the form of a suspension would, but without the use of a liquid, which in turn would cause the Hydrogenation from the coal to be extracted materials is of the same nature, so that they at the Participate in the hydrogenation process and during 'the process a further conversion able to experience.
; Der günstige Einfluß d.er Anwendung eines j flüssigen Kohlehydrierungspraduktes zur Aufschwemmung der durch Hydrierung zu verflüssigenden Kohle ist aus nachstehenden j Vergleichsversuchen ersichtlich:; The favorable influence of the use of a liquid carbohydrate product for suspension the coal to be liquefied by hydrogenation is from the following j comparison tests can be seen:
