Description

Verfahren zur Darstellung von Methylalkohol und anderen sauerstoffhaltigen organischen Verbindungen aus Kohlenoxyd und Wasserstoff Die Gewinnung eines für die Herstellung von Methanol oder anderen sauerstoffhaltigen, organischen Verbindungen unter erhöhtem Druck aus technischen Kohlenoxyd und Wasserstoff enthaltenden Gasgemischen bietet oftmals Schwierigkeiten, da es erst umständlicher und kostspieliger Reinigungsmethoden bedarf, um die insbesondere beim Arbeiten im Dauerbetrieb schädlichen Verunreinigungen, vor allem die organischen Schwefelverbindungen, die sich vielfach selbst durch Behandlung mit Kupfer bei 6oo' nicht restlos entfernen lassen, zu beseitigen.Process for the preparation of methyl alcohol and other oxygen-containing organic compounds from carbon monoxide and hydrogen The extraction of a for the production of methanol or other oxygen-containing organic compounds under increased pressure from technical gas mixtures containing carbon oxide and hydrogen often presents difficulties because of the cumbersome and costly cleaning methods in order to avoid the contamination, which is particularly harmful when working in continuous operation, especially the organic sulfur compounds, which are often self-treated by treatment Do not allow to be completely removed with copper at 6oo ', to be removed.

In dem Hauptpatent 396115 ist bereits ein Verfahren zur Herstellung von Methan beschrieben, bei dem das zur Reaktion gelangende Gasgemisch zwecks Reinigung zuvor einer teilweisen katalytischen Umzetzung des Kohlenoxyds mittels Wasserdampfs unterworfen und von dem hierbei entstehenden Schwefelwasserstoff befreit wird.In the main patent 396115 a method for production is already of methane, in which the gas mixture which reacts for the purpose of purification before a partial catalytic conversion of the carbon oxide by means of steam is subjected and freed from the resulting hydrogen sulfide.

Es hat sich nun gezeigt, daß es bei der überführung von Wassergas und anderen Kohlenoxyd und Wasserdampf enthaltenden Gemischen von technischen Gasen auf katalytischem Wege unter erhöhtem Druck in sauerstoffhaltige organische Verbindungen ebenfalls von Vorteil ist, das Gasgemisch zuvor mit Wasserdampf in Gegenwart eines Katalysators zur teilweisen Cberführung des Kohlenoxyds in Kohlendioxyd zu behandeln und darauf den entstandenen Schwefelwasserstoff sowie sonstige Verunreinigungen zu entfernen. Auf diese Weise werden die organischen in Schwefelwasserstoff umgewandelt, der sich leicht beseitigen läßt; und es gelingt so, das Wassergas und andere ähnliche Gemische von technischen Gasen für den Dauerbetrieb der katalytischen Gewinnung von Methylalkohol usw., bei der schon geringe Mengen organischer Schwefelverbindungen sehr schädlich wirken, geeignet zu machen.It has now been shown that in the transfer of water gas and other mixtures of industrial gases containing carbon monoxide and water vapor catalytically under increased pressure into oxygen-containing organic compounds is also advantageous, the gas mixture beforehand with steam in the presence of a To treat catalyst for partial conversion of the carbon dioxide into carbon dioxide and then the resulting hydrogen sulfide and other impurities to remove. In this way the organic ones are converted into hydrogen sulfide, which can be easily removed; and it succeeds so, the water gas and other similar Mixtures of technical gases for continuous operation in catalytic extraction of methyl alcohol, etc., in which even small amounts of organic sulfur compounds act very harmful to make suitable.

Beispiel Vorgereinigtes Wassergas mit z. B. 38 0;b Kohlenoxyd und 4.8 % Wasserstoff (der Rest besteht zur Hauptsache aus Kohlensäure und Stickstoff) wird mit Wasserdampf gemischt und bei ungefähr 6oo° über einen. aktivierten Eisenoxydkontakt mit einer solchen Geschwindigkeit geleitet, daB sich ungefähr die Hälfte des Kohleztöxyds - mitJ dem Wasserdampf zu Kohlenoxyd und Wasserstoff umsetzt. -Dabei gehen die organischen SchwefelverbIndungen in Schwefelwasserstoff über, der danach aus dem Gasgemisch, gegebenenfalls zusammen mit der Kohlensäure oder einem Teil davon entfernt wird. Das nunmehr schwefelfreie Gasgemisch wird komprimiert und z. B. bei 3oo bis 500° über einen Katalysator zur Gewinnung von Methylalkohol u. dgl. geleitet.Example prepurified water gas with z. B. 38 0; b carbon oxide and 4.8% hydrogen (the rest consists mainly of carbonic acid and nitrogen) is mixed with steam and at about 6oo ° over a. activated Iron oxide contact conducted at such a rate that about half of the coal oxide - Reacts with the water vapor to carbon oxide and hydrogen. -These go organic Sulfur compounds are converted into hydrogen sulfide, which is then extracted from the gas mixture, if necessary, is removed together with the carbonic acid or part of it. The now sulfur-free gas mixture is compressed and z. B. at 3oo to 500 ° passed over a catalyst for the recovery of methyl alcohol and the like.

Auch die Vorbehandlung mit Wasserdampf sowie die Entfernung des Schwefelwasserstoffs kann gegebenenfalls unter Druck ausgeführt werden.Also the pretreatment with steam and the removal of the hydrogen sulfide can optionally be carried out under pressure.

Das so erhaltene Gasgemisch ist wesentlich reiner als das unbehandelte beispielsweise durch Absorption mit ammoniakalischer Kupferoxydullösung auf den gleichen Kohlenoxydgehalt gebrachte Wassergas.The gas mixture obtained in this way is much purer than the untreated one for example by absorption with ammoniacal copper oxide solution on the water gas brought with the same carbon oxide content.
