Description
Verfahren zur Ausfuehrung von Reaktionen zwischen Hochdruckgasen und festen Stoffen.Process for carrying out reactions between high pressure gases and solid substances.
Reaktionen zwischen festen Stoffen und Gasen unter hohen Drucken, insbesondere wenn es sich um kontinuierliches Arbeiten handelt, sind technisch nur unzulänglich ausführbar, da es bisher nicht möglich war, die fe-sten Stoffe in feinster Verteilung - wie sie für den leichten Verlauf der Reaktion von großer Bedeutung ist - dem Hochdruckraum zuzuführen. Auch die Abführung etwa vorhandener fester Reaktionsprodukte oder Rückstände, wie z. B. die bei der Hydrierung von Kohle sich ergebenden Aschenbestandteile, läßt sich bei den bisher bekannten Verfahren nur schwer ausführen. Reactions between solids and gases under high pressure, especially when it comes to continuous work, are only technically inadequately feasible, since it was previously not possible to produce the solid materials in the finest Distribution - as they are of great importance for the easy course of the reaction - is to be fed to the high pressure chamber. Also the removal of any solid reaction products that may be present or residues such as B. the ash components resulting from the hydrogenation of coal, can only be carried out with difficulty in the previously known methods.
Es wurde nun gefunden, daß sich solche Reaktionen zwischen Gasen und festen Stoffen kontinuierlich gut bewerkstelligen lassen, wenn man den festen Stoff in Staubform nicht in das schon unter Druck stehende Gas, sondern bei Atmosphärendruck in das Gas einbringt und das staubhaltige Gas hierauf komprimiert. Zweckmäßig komprimiert man hierbei in einer Stufe auf einen etwas höheren Druck, als er in dem Reak- -tionsraum herrscht, so daß das Gemisch einfach durch Ventile in diesen eintreten kann. It has now been found that such reactions occur between gases and solids continuously manage well if you can use the solids Substance in dust form not in the gas that is already under pressure, but at atmospheric pressure introduces into the gas and then compresses the dusty gas. Appropriately compressed one here in one stage to a slightly higher pressure than in the reaction space prevails so that the mixture can easily enter these through valves.
Bei der Komprimierung wird das Gas sehr stark erhitzt und tritt dann mit einer Temperatur von mehreren Hundert Grad in den Apparat ein, der durch entsprechende Kühlung an der Eintrittsstelle auf der gewünschten Temperatur gehalten werden kann. Es ergibt sich also der weitere Vorteil, daß bei Ausführung von Reaktionen, die nicht allzuhohe Temperaturen erfordern, eine besondere Heizung des Reaktionsraumes überflüssig ist.During compression, the gas is heated very strongly and then occurs with a temperature of several hundred degrees in the apparatus, which is by appropriate Cooling at the entry point can be kept at the desired temperature. So there is the further advantage that when executing reactions that temperatures that are not too high require special heating of the reaction space is superfluous.
Man kann beispielsweise derart verfahren, daß man in einen senkrecht stehenden Reaktionsofen von langer zylindrischer Form an dessen oberem Ende ein Gemisch einpreßt von Wasserstoff mit feinstem Braunkohlenstaub, das bei Atmosphärendruck hergestellt und in einem Gang auf 150 Atm. gepreßt worden ist. Der Staub sinkt im Druckraum infolge der hohen Dichte des komprimierten Gases sehr langsam unter Reaktion mit dem Wasserstoff nach unten; es bilden sich hierbei wertvolle Kohlenwasserstoffe, die durch Kühlung kondensiert werden. Hierbei schlägt sich der Aschenstaub mit nieder und wird zusammen mit der Flüssigkeit, in der er suspendiert ist, abgezogen. One can, for example, proceed in such a way that one enters one vertically standing reaction furnace of long cylindrical shape at its upper end Mixture injects hydrogen with the finest lignite dust at atmospheric pressure produced and in one go to 150 atm. has been pressed. The dust sinks in Pressure chamber reacts very slowly due to the high density of the compressed gas with the hydrogen down; valuable hydrocarbons are formed here, which are condensed by cooling. The ash dust is also precipitated here and is withdrawn along with the liquid in which it is suspended.
Nach dem vorliegenden Verfahren können Stoffe jeder Art, die sich in feine Verteilung bringen lassen, mit Gasen in Reaktion gebracht werden, z. B. feinpulveriger Torf, Steinkohle usw., wie auch Rohstoffe für Reaktionen anderer Art, z. B. Oxydationen oder Reduktionen. Auch können Kontaktmassen in Staubform allein oder zusammen mit umzusetzenden festen Körpern in dieser Weise Gasen für Reaktionen unter Druck zugeführt werden. According to the present process, substances of any kind that are can be brought into fine distribution, reacted with gases, e.g. B. finely powdered peat, coal, etc., as well as raw materials for the reactions of others Kind, e.g. B. Oxidations or reductions. Contact masses can also be in the form of dust alone or together with solid bodies to be converted in this way gases for Reactions are fed under pressure.
