Description
Verfahren und Vorrichtung zur Umwandlung flüssiger Körper.Method and device for converting liquid bodies.
Bei der chemischen Umwandlung eines flüssigen Körpers durch Absorption irgendeines Gases in Gegenwart eines Katalysators verfuhr man bisher meistens so, daß man den betreffenden Katalysator in die Flüssigkeit einbrachte, ihn mit Hilfe eines Rührwerkes fein verteilte und das betreffende Gas einleitete. In the chemical transformation of a liquid body through absorption of any gas in the presence of a catalyst has hitherto usually been done as follows: that the catalyst in question was brought into the liquid, with the help of it a stirrer finely distributed and introduced the gas in question.
Diesem Verfahren haften gewisse Nachteile an, die ihren Grund hauptsächlich in der schlechten Verteilung des Katalysators haben. This method has certain disadvantages, the main reason for which have in the poor distribution of the catalyst.
Es ist auch bereits vorgeschlagen worden, Flüssigkeit und Katalysator einen geschlossenen Kreislauf ausführen zu lassen, wobei das betreffende Gas im Gegenstrom in einem Abschnitt des Kreislaufes durch die Flüssigkeit hindurchgeleitet wird. Hierbei wird die in einem Autoklaven befindliche Flüssigkeit mitsamt dem darin aufgeschwemmten Katalystator mit Hilfe einer Pumpe abgezogen, emporgehoben und in einem weiteren Autoklaven oben durch düsenartige Sprüher wieder fein verteilt, so daß sie als Regen herabfliest. Das zu absorbierende Gas wird durch die im unteren Teil des Autoklaven befindliche Flüssigkeit geleitet, rührt diese intensiv auf und steigt dann im Gegenstrom zu der als Regen herabrieselnden Flüssigkeit im Autoklaven empor, wird oben abgezogen, mittels eines Kompressors verdichtet und der Mischdüse wieder zugeführt. It has also been suggested before, liquid and catalyst to run a closed circuit, with the gas in question in Passed countercurrent in a section of the circuit through the liquid will. Here, the liquid in an autoclave together with the Floated catalyst withdrawn with the help of a pump, lifted up and in finely distributed in another autoclave above by nozzle-like sprayers, see above that it flows down as rain. The gas to be absorbed is through the in the lower Part of the autoclave located liquid passed, this stirs intensively and then rises in countercurrent to the liquid trickling down as rain in the autoclave up, is drawn off at the top, compressed by means of a compressor and the mixing nozzle fed back.
Bedeutete diese Abänderung des ursprünglichen Verfahrens bereits einen wesentlichen Fortschritt auf diesem Gebiete, so erfordert der Gesamtprozeß für seine Durchführung immerhin noch ziemlich viel Zeit. So benötigte z. B. beim Hydrieren von Ölen und Fetten mit Hilfe des verbesserten Verfahrens die Anreicherung dieser Stoffe mit Wasserstoff immerhin eine Zeit von 15 bis 17 Stunden. This modification of the original procedure already meant The overall process calls for a substantial advance in this area after all, there is still quite a bit of time left for its implementation. So z. B. at Hydrogenation of oils and fats with the help of the improved enrichment process these substances with hydrogen at least a time of 15 to 17 hours.
Es wurde nun erkannt, daß gegenüber den bekannten Verfahren ein ganz wesentlicher technischer Fortschritt zu erzielen ist, wenn man auch das Emporheben der Mischung von Flüssigkeit und Katalysator durch das an der Reaktion beteiligte Gas bewirkt, wodurch eine erhöhte Wirkung des Katalysators in der eigentlichen Anreicherungszone des Kreislaufes zustande kommt. Verfährt man auf diese Weise, so tritt das sehr auffällige Ergebnis zutage, daß man zu derselben Anreicherung, zu der man bisher 15 bis I7 Stunden benötigte, nur 31/2 bis 4 Stunden braucht. It has now been recognized that compared to the known method a very Making substantial technical progress is when you also get uplifting the mixture of liquid and catalyst by that involved in the reaction Gas causes, whereby an increased effect of the catalyst in the actual enrichment zone of the cycle comes about. If one proceeds in this way, it is very bad A striking result comes to light that one has reached the same enrichment that one has hitherto achieved Took 15 to 17 hours, only needed 31/2 to 4 hours.
Der Grund hierfür ist darin zu erblicken, daß bei dem Emporpumpen der Flüssigkeit der darin verteilte, jetzt außer Berührung mit dem Gas gekommene Katalysator seine Aktivität teilweise einbüßt, die er bei neuer Berührung mit dem Gas erst allmählich wieder gewinnt.The reason for this is to be seen in the fact that during the pumping up the liquid distributed in it, now out of contact with the gas The catalyst loses some of its activity when it comes into contact with the Gas only gradually regains.
Beim Herabregnen der Flüssigkeit im Gasraum des Autoklaven geht also ein Teil des Weges, auf dem sich Katalysator und Gas berühren, verloren, weil der Katalysator beim Zurücklegen dieser Wegstrecke erst seine volle Aktivität wiedergewinnen muß.So when the liquid rains down in the gas space of the autoclave part of the way on which the catalyst and gas meet is lost because of the Catalyst only regain its full activity when covering this distance got to.
Im Gegensatz hierzu bleibt der Katalysator bei dem neuen Verfahren in ständiger Berührung mit dem Gas, seine Wirkung wird also fortwährend ohne Unterbrechungen ausgenutzt und die gegenseitige Einwirkung zwischen Gas, Flüssigkeit und Katalysator findet nicht nur in einem verhältnismäßig kleinen Teil, sondern in allen Teilen des Kreislaufes statt. In contrast, the catalyst remains with the new process in constant contact with the gas, so its effect is continuous without interruptions exploited and the mutual interaction between gas, liquid and catalyst found not only in a relatively small part, but in all parts of the cycle.
Als besonders vorteilhaft hat sich hierbei die Verwendung zweier Gaskreisläufe herausgestellt, von denen der eine an dem einen Teil des Flüssigkeitskreislaufes in der Bewegungsrichtung dieses, der andere an dem anderen Teil des Flüssigkeitskreislaufes, aber in entgegengesetzter Richtung, teilnimmt, zu welchem Zwecke die Kompressionspumpe mit der einen Druckseite an den einen, mit der anderen Druckseite an den anderen Kreislauf geschaltet sein kann. The use of two has proven to be particularly advantageous here Gas circuits highlighted, one of which on one part of the liquid circuit in the direction of movement this, the other on the other part of the fluid circuit, but in the opposite direction, the purpose of the compression pump takes part with one pressure side to one, with the other pressure side to the other Circuit can be switched.
Auf der Zeichnung ist ein Ausführungsbeispiel einer Vorrichtung zur Durchführung des \~erfahrens schematisch im Schnitt dargestellt. In the drawing is an embodiment of a device for Implementation of the process shown schematically in section.
Das zylindrische, oben geschlossene Gefäß I, in welchem das Verfahren ausgeführt werden soll, verläuft nach unten bei 2 trichterförmig wie bei den bereits bekannten Vorrichtungen, so daß alle in der Flüssigkeit nach unten sinkende Teilchen der Einlaßöffnung 3 eines Mischgasflüssigkeitshebers 4 zugeführt werden. Der Ausfluß 5 des Flüssigkeitshebers 4 mündet in ein Verteilungsgefäß 6, dessen Boden 7 durchlöchert ist und die ihm zugeführte Flüssigkeit fein verteilt herabrieseln läßt. Der Ausfluß 5 ist etwas über dem Boden 7 erhöht. Konzentrisch um den unteren Teil des Mischgasflüssigkeibshebers ist ein mit düsenförmigen, nach oben gerichteten Öffnungen versehenes Ringrohr 8 angeordnet, welches durch eine Leitung 9 mit der einen Drucliseite einer Koinpressionspumpe 10 in Verbindung steht. Die andere Druckseite der Pumpe ist durch die Leitung II mit dem Mischgasflüssigkeitsheber 4 bei 3 in Verbindung gebracht, während beide Saugseiten der Pumpe durch die Leitung I2 an das Gefäß I oberhalb des Flüssigkeitsspiegels angeschlossen sind. The cylindrical vessel I, closed at the top, in which the process is to be carried out, runs downwards at 2 in a funnel shape as in the case of the already known devices, so that all particles sinking down in the liquid the inlet port 3 of a mixed gas liquid siphon 4 are supplied. The discharge 5 of the liquid siphon 4 opens into a distribution vessel 6, the bottom 7 of which is perforated and allows the liquid supplied to it to trickle down in finely divided form. The discharge 5 is slightly raised above the floor 7. Concentric around the lower part of the mixed gas liquid lift is an annular tube 8 provided with nozzle-shaped, upwardly directed openings arranged, which through a line 9 with the one pressure side of a Koinpressionspumpe 10 communicates. The other pressure side of the pump is through line II associated with the mixed gas liquid siphon 4 at 3, while both Suction side of the pump through line I2 to vessel I above the liquid level are connected.
Die Wirkungsweise der Vorrichtung ist die folgende: Nachdem die Flüssigkeit mit dem betreffenden Katalysator in den Behälter I eingebracht ist, wird die Kompressionspumpe in Tätigkeit gesetzt, welche das betreffende zu absorbierende Gas aus einem beliebigen Behälter ansaugt und zum Teil in den Mischgasflüssigkeitsheber 3, zum Teil in das Rmgrohr 8 pumpt. Die Folge davon ist, daß einesteils ein lebhafter Kreislauf der Flüssigkeit in Richtung der Pfeile hervorgerufen, anderseits Gas entgegengesetzt dieser Richtung durch die Flüssigkeit hindurchgepreßt wird. The operation of the device is as follows: After the liquid is placed with the catalyst in question in the container I, the compression pump put into action which the gas in question to be absorbed from any Sucks in the container and partly into the mixed gas liquid siphon 3, partly into the Rm pipe 8 pumps. The consequence of this is that, on the one hand, there is a lively cycle of Liquid caused in the direction of the arrows, on the other hand gas in the opposite direction this direction is pressed through the liquid.
Zugleich mit der Flüssigkeit muß der Katalysator den eben bezeichneten Kreislauf mitmachen, kommt dabei in innige Berührung mit der Flüssigkeit einerseits und dem Gas anderseits und wird außerdem nach Möglichkeit zerkleinert, so daß die Gesamtberührungsfläche größer wird. Beim Wiederherabsinken im Flüssigkeitsstrom außerhalb des Mischgasflüssigkeitshebers 4 kommt er mit dem aufsteigenden Gasstrom abermals in innigste Berührung, so daß die Absorption des Gases in Gegenwart des Katalysators besonders intensiv wird. Das nicht absorbierte Gas sammelt sich oberhalb des Flüssigkeitsspiegels und wird vom Kompressor 10 durch die Leitung 12 angesaugt, um dem Kreislauf entweder durch den Mischgasflüssigkeitsheber 4 oder durch das Ringrohr 8 direkt wieder zugeführt zu werden. Die während des Prozesses absorbierte Gasmenge wird durch Zuleiten frischen Gases entweder in den Kompressor oder in den Behälter I ergänzt. Auf diese Weise ist es auch möglich, das Verfahren unter allmählicher Druckerhöhung durchzuführen, indem mehr frisches Gas zugeführt wird als die Flüssigkeit absorbieren kann.At the same time as the liquid, the catalyst must have the same name Participating in the cycle, you come into close contact with the liquid on the one hand and the gas on the other hand and is also crushed if possible so that the Total contact area becomes larger. When descending again in the liquid flow outside of the mixed gas liquid siphon 4, it comes with the ascending gas flow again in intimate contact, so that the absorption of the gas in the presence of the Catalyst is particularly intense. The unabsorbed gas collects above the liquid level and is sucked in by the compressor 10 through the line 12, around the circuit either through the mixed gas liquid siphon 4 or through the ring tube 8 to be fed back directly. The amount of gas absorbed during the process is made by feeding fresh gas either into the compressor or into the container I added. In this way it is also possible to take the procedure more gradually Carry out pressure increase by adding more fresh gas than the liquid can absorb.
Obwohl das Verfahren sich überall dort vorteilllaft anwenden läßt, wo in der chemischen oder verwandten Industrie es darauf ankommt, einen flüssigen Körper durch Absorption eines Gases in Gegenwart eines Katalysators umzuwandeln, eignet es sich besonders gut zur Anlagerung von Wasserstoff an flüssige Kohlenwasserstoffe in Ge-Gegenwart eines beliebigen Katalysators. Although the procedure can be used advantageously everywhere, where in the chemical or related industry it is important to have a liquid Transforming bodies by absorbing a gas in the presence of a catalyst, it is particularly suitable for the addition of hydrogen to liquid hydrocarbons in the presence of Ge of any catalyst.
