Description
Verfahren zur Gewinnung ton wertvollen sauerstoffhaltigen Produkten Bei der Behandlung von Oxyden des Kohlenstoffes mit Wasserstoff unter Druck und bei erhöhter Temperatur zwecks Gewinnung wertvoller sauerstoffhaltiger Produkte, .wie Methylalkohol und Isobutylöle, zeigt sich, daß die Wirkung der Katalysatoren nach kürzerer oder längerer Gebrauchsdauer nachläßt oder gar ganz aufhört. Diese Erscheinung scheint darauf zurückzuführen zu sein, daß die Ausgangsstoffe während der Reaktion höhermolekulare Stoffe bilden, die sich in die Poren der Katalysatoren setzen und deren Wirksamkeit dadurch lahmlegen.Process for the extraction of valuable oxygenated products When treating oxides of carbon with hydrogen under pressure and at elevated temperature for the purpose of obtaining valuable oxygen-containing products, Like methyl alcohol and isobutyl oils, it is shown that the effect of the catalysts decreases or even stops completely after a shorter or longer period of use. These Appearance seems to be due to the fact that the starting materials during During the reaction, higher molecular weight substances form, which can be found in the pores of the catalysts and thereby paralyze their effectiveness.
Es hat sich nun überraschenderweise gezeigt, daß bei der genannten Arbeitsweise die Wirksamkeit der Katalysatoren erhalten bleibt, wenn man ein Festsetzen hochmolekularer Stoffe auf dem Katalysator während der Reaktion durch die Gegenwart hochsiedender, unter den Reaktionsbedingungen praktisch sich nicht verändernder Lösungsmittel verhindert. Als derartige Lösungsmittel kommen beispielsweise Anthracenöl oder ähnliche Öle; namentlich solche aromatischer Natur, in Betracht.It has now been shown, surprisingly, that in said Working method the effectiveness of the catalysts is retained if one sets High molecular weight substances on the catalyst during the reaction due to the presence high-boiling, practically unchanged under the reaction conditions Solvent prevented. Examples of such solvents are anthracene oil or similar oils; especially those of an aromatic nature.
Vorteilhaft ist es, derart zu arbeiten, daß man die im Reaktionsraum befindlichen Lösungsmittel ständig aus diesem heraus- und ohne Abkühlung wieder in diesen zurückführt, wobei gegebenenfalls auch größere Mengen von Reaktionsgasen mit umgepumpt werden können.It is advantageous to work in such a way that the in the reaction chamber located solvent constantly out of this and again without cooling recycled into these, where appropriate also larger amounts of reaction gases can be pumped with.
Um eine zu starke Anreicherung unerwünschter hochmolekularer Stoffe in dem Lösungsmittel zu verhindern, kann dieses kontinuierlich oder in gewissen Zeitabständen erneuert werden, z. B. indem die im Reaktionsraum befindliche Flüssigkeit durch ein Filter aus dem Reaktionsraum abgezogen wird, so daß der Katalysator im Reaktionsraum verbleibt, oder indem man die flüssige Masse ganz oder teilweise aus dem Reaktionsraum entfernt, Katalysatoren und Flüssigkeit trennt und erstere, gegebenenfalls nach Regenerierung, die mit oder ohne Anwendung von Druck erfolgen kann, z. B. durch Mahlen in schnell laufenden Mühlen, dem Reaktionsraum zuführt.To an excessive accumulation of undesirable high molecular substances to prevent this in the solvent, this can be continuous or in certain Be renewed at intervals, z. B. by the liquid in the reaction chamber is withdrawn through a filter from the reaction chamber, so that the catalyst in Reaction space remains, or by completely or partially removing the liquid mass removed from the reaction space, separating catalysts and liquid and the former, if necessary after regeneration, which can be done with or without the application of pressure, e.g. B. by Milling in high-speed mills fed into the reaction chamber.
Es war bereits bekannt, bei der Hydrierung von Teer-, Mineralöl u. dgl. (französische Patentschrift 637 ozz) die Wirksamkeit der Katalysatoren dadurch zu erhalten, daß man die auf ihnen niedergeschlagenen höhermolekularen Stoffe durch Einführung eines niedrigsiedenden dampfförmigen Lösungsmittels in den Reaktionsraum entfernt. Bei der katalytischen Druckhydrierung von Kohlenoxyden handelt es sich um eine Gasreaktion zwecks Gewinnung wesentlich anderer Produkte. Es war daher auch nicht ohne weiteres gegeben, bei einer solchen Gasreaktion die Wirksamkeit der Katalysatoren durch Einführung eines flüssigen hochsiedenden Lösungsmittels in den Reaktionsraum zu erhalten.It was already known in the hydrogenation of tar, mineral oil and. Like. (French patent 637 ozz) thereby the effectiveness of the catalysts to get that you get the precipitated on them higher molecular weight substances through Introduction of a low-boiling, vaporous solvent into the reaction space removed. The catalytic pressure hydrogenation of carbon oxides is a gas reaction for the purpose of obtaining substantially different products. So it was not given without further ado, the effectiveness of such a gas reaction the catalysts by introducing a liquid high-boiling solvent to get into the reaction chamber.
Beispiel Leitet man über einen durch Zusammenschmelzen von Zinkoxyd und Calciumbichromat erhaltenen Katalysator bei 39o bis 4oo° und einem Druck von Zoo Atm. ein Gemisch von etwa 30 % C O und 7o °1a EI" so erhält man ein Gemisch höherer Alkohole. Zu einem kleinen Teil entstehen aber auch hochmolekulare Verbindungen, die sich auf dem Katalysator niederschlagen und so langsäm dessen Aktivität schwächen. Führt man nun die erwähnte Reaktion so aus, daß man während des Gasdurchgangs durch den Kontakt diesen ständig mit einem im Kreislauf befindlichen, unter den Arbeitsbedingungen praktisch nicht spaltbaren, möglichst asphaltfreiem Öl, z. B. Anthracenöl, bespült, so werden die bei der Reaktion entstehenden hochmolekularen Verbindungen im Spülöl gelöst gehalten, so daß sie sich nicht auf dem Katalysator niederschlagen können. Dieser behält also seine Aktivität praktisch dauernd bei. Sind die hochmolekularen Verbindungen im Kreislauföl stark angereichert, so ist es zweckmäßig, dieses zu erneuern.Example One passes over a by melting zinc oxide together and calcium dichromate obtained catalyst at 39o to 4oo ° and a pressure of Zoo Atm. a mixture of about 30% CO and 70 ° 1a EI ", a mixture is obtained higher alcohols. To a small extent, however, high-molecular compounds are also formed, which are deposited on the catalyst and so slowly weaken its activity. If the reaction mentioned is now carried out in such a way that it is carried out during the passage of gas constant contact with someone in circulation under the working conditions practically non-fissile, asphalt-free oil, z. B. Anthracene oil, rinsed, this is how the high molecular weight compounds formed during the reaction are in the flushing oil kept dissolved so that they can not be deposited on the catalyst. This thus practically permanently maintains its activity. Are the high molecular weight Compounds in the circulatory oil are heavily enriched, so it is advisable to use this too renew.
