KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gemäß Patent 293787 erhält man Kohlenwasserstoffe, insbesondere solche flüssiger oder leicht zu verflüssigender Natur, und von Kohlenwasserstoffen abgeleitete Verbindungen, wenn man Oxyde des Kohlenstoffs mit Wasserstoff in Gegenwart von Katalysatoren bei höheren Drucken zur Reaktion bringt.According to patent 293787 one obtains hydrocarbons, especially those liquid or easily liquefied in nature, and compounds derived from hydrocarbons if one oxides of carbon with hydrogen in the presence of catalysts at higher Printing makes a reaction.
Es hat sich nun als vorteilhaft erwiesen, zur Ausführung dieses Verfahrens insbesondere bei Gegenwart von Kohlenoxyd im Gasgemisch Kontaktmassen von hoher Wärmeleitfähigkeit zu verwenden. Es kann dadurch die sonst unter Umständen auftretende, störende heftige Spaltung von Kohlenoxyd unter Kohleabscheidung und die hierdurch bedingte lokale Überhitzung vermieden werden.It has now proven advantageous, in particular, for carrying out this method in the presence of carbon oxide in the gas mixture, contact masses of high thermal conductivity to use. This can lead to the annoying violent effects that may otherwise occur under certain circumstances Cleavage of carbon oxide with carbon deposition and the resulting local Overheating can be avoided.
Um Kontaktmassen von hoher Wärmeleitfähigkeit zu erhalten, kann man beispielsweise dem etwa auf keramische Träger niedergeschlagenen Katalysator Stücke granulierten oder stäbchenförmigen Metalles, wie Kupfer u. dgl., beimischen, oder den Katalysator auf gut wärmeaufnehmendes und -leitendes Metall aufbringen oder aber unmittelbar kompaktes, katalytisch wirkendes Metall in Form von Schnitzeln, Wolle, Drahtnetz u. dgl., die zweckmäßig vorher aktiviert werden, benutzen. Vorteilhaft wird gleichzeitig durch entsprechende Temperaturregelung im Reaktionsraum für eine gute Temperaturkonstanz gesorgt.In order to obtain contact masses of high thermal conductivity, one can, for example granulated pieces of the catalyst deposited on a ceramic carrier or rod-shaped metal such as copper and the like, or the catalyst Apply metal that absorbs and conducts heat well or directly compact, catalytically active metal in the form of chips, wool, wire mesh and the like activated beforehand. At the same time, it is advantageous through appropriate Temperature control in the reaction chamber ensures good temperature constancy.
Reines Nickeldrahtnetz (z. B. in Röllchenform), das zweckmäßig angeätzt und mit Stoffen wie Alkali, Zinkoxyd, Kobaltoxyd o. dgl. aktiviert worden ist, wird in ein passendes druckfestes Rohr, das innen mit Kupfer ausgekleidet ist, eingeführt. Man erhitzt das Rohr ζ. B. in einem Heizbad gleichmäßig auf etwa 350 bis 400° und führt ein vorgeheiztes, auf z. B. 100 Atm. komprimiertes Gasgemisch zu, das auf 1 Volumen Wasserstoff 1 bis 2 Volumen Kohlenoxyd enthält. Sobald die Reaktion eintritt, werden Gasgeschwindigkeit und Wärmezufuhr bzw. Abfuhr passend geregelt, worauf eine gleichmäßige Bildung höherer Kohlenwasserstoffe u. dgl. erfolgt. Das Gas kann geringe Mengen Eisencarbonyl enthalten. Pure nickel wire mesh (e.g. in the form of a roll), which is appropriately etched and with Substances such as alkali, zinc oxide, cobalt oxide o. The like. Has been activated, is converted into a suitable pressure-resistant pipe, which is lined with copper on the inside, introduced. You heat that Tube ζ. B. in a heating bath evenly to about 350 to 400 ° and performs a preheated, on z. B. 100 atm. compressed gas mixture to 1 volume of hydrogen 1 to 2 volumes Contains carbon monoxide. As soon as the reaction occurs, the gas speed and heat supply or removal are appropriately regulated, whereupon a uniform formation of higher hydrocarbons and the like takes place. The gas may contain small amounts of iron carbonyl.
Man hat schon in dem speziellen Fall der Darstellung von Aceton aus Essigsäure als Träger für die reagierenden Stoffe gute Wärmeleiter verwendet, doch bot dieses auf einem ganz anderen Gebiete liegende Verfahren keinen Anhaltspunkt dafür, daß bei der katalytischen Behandlung von Kohlenoxyd-Wasserstoff-Gemischen unter Druck die sonst mehrfach unter Kohlenstoffabscheidung auftretenden Ausbeuterückgänge und die ebenso unerwünschten und unter Umständen gefährlichen spontanen plötz-One has already in the special case of the preparation of acetone from acetic acid as Carrier used for the reacting substances good heat conductors, but this offered on one There is no evidence that the catalytic Treatment of carbon-oxide-hydrogen mixtures under pressure which is otherwise several times under Declines in yield and the equally undesirable and potentially dangerous spontaneous sudden

Hierin liegt eine überraschende neue Erkenntnis, auf Grund welcher ein außerordentlich/wichtiger Effekt erzielt wird.increases in temperature and pressure Application of the stressed contact masses of high thermal conductivity can be eliminated can. Herein lies a surprising new finding, on the basis of which an extraordinarily / important Effect is achieved.
