Description
Die Erfindung bezieht sich auf die Erzeugung von methanhaltigen Gasen aus Mischungen von vorwiegend paraffinischen Kohlenwasserstoffen, die im Mittel 4 bis 10 Kohlenstoffatome enthalten, wie z. B. Erdöldestillaten, durch Umsetzung mit Wasserdampf in Gegenwart eines Katalysators.The invention relates to the generation of methane-containing gases from mixtures of predominantly paraffinic hydrocarbons containing an average of 4 to 10 carbon atoms, such as. B. Petroleum distillates, by reaction with steam in the presence of a catalyst.
Es ist bekannt, methanhaltige Gase aus Mischungen von niedrigsiedenden Kohlenwasserstoffen, die Schwefel als Verunreinigung enthalten, dadurch zu erzeugen, daß man den Dampf der Kohlenwasserstoffe mit Wasserdampf in Gegenwart eines Nickelkatalysators bei Temperaturen zwischen etwa 870 und 1040° C zur Bildung eines Gemisches, das im wesentlichen aus Wasserstoff und Kohlenmonoxyd besteht, umsetzt, das Gemisch durch einen Schwefeladsorber oder -wäscher führt und das gereinigte Gemisch zur Bildung von Methan bei Temperaturen zwischen 260 und 482° C mit einem Nickelkatalysator in Berührung bringt. Das bekannte Mehrstufenverfahren hat den Nachteil, daß in der ersten Stufe eine besondere Wärmezufuhr erforderlich ist, da die Umsetzung der Kohlenwasserstoffe mit Wasserdampf zur Bildung eines Gemisches von Wasserstoff und Kohlenmonoxyd endotherm ist. Zu diesem Zweck muß entweder Sauerstoff der ersten Stufe zugeführt werden, um Wärme durch Verbrennung in der Reaktionszone freizusetzen, oder es ist eine besondere Erhitzung des in einer Vielzahl von Rohren vorgesehenen Katalysators von außen erforderlich. Solche Arbeitsweisen unter Erzeugung von Wärme bzw. mit besonderer Wärmezufuhr sind sowohl hinsichtlich des Betriebes als· auch der erforderlichen Apparatur kostspielig und unwirtschaftlich.It is known to produce methane-containing gases from mixtures of low-boiling hydrocarbons which Contain sulfur as an impurity, produced by the fact that one produces the vapor of the hydrocarbons with steam in the presence of a nickel catalyst at temperatures between about 870 and 1040 ° C to form a mixture consisting essentially of hydrogen and carbon monoxide consists, converts, the mixture passes through a sulfur adsorber or scrubber and the purified Mixture for the formation of methane at temperatures between 260 and 482 ° C with a nickel catalyst brings in touch. The known multi-stage process has the disadvantage that in the first Stage a special supply of heat is required because the reaction of the hydrocarbons with water vapor is endothermic to form a mixture of hydrogen and carbon monoxide. To this Purpose must either be fed to the first stage oxygen to heat by combustion in to release the reaction zone, or it is a special heating of the in a variety of tubes provided catalyst required from the outside. Such working methods with the generation of heat or with a special supply of heat are required both in terms of operation and · Apparatus expensive and uneconomical.
Es ist ferner ein Verfahren bekannt, gemäß welchem aus Dieselöl und Kerosin Ölgas (hauptsächlich H2, CH4, C2H4 und CO) durch Erhitzen auf 700 bis 900° C unter Anwendung eines Nickelkatalysators und in Gegenwart von Wasserdampf hergestellt wird. Es werden bei dieser Arbeitsweise in Übereinstimmung mit dem bei hohen Reaktionstemperaturen herrschenden Reaktionsgleichgewicht nur sehr geringe Mengen von Methan und in der Hauptsache Kohlenmonoxyd und Wasserstoff er-A method is also known according to which oil gas (mainly H 2 , CH 4 , C 2 H 4 and CO) is produced from diesel oil and kerosene by heating to 700 to 900 ° C. using a nickel catalyst and in the presence of steam. In this procedure, in accordance with the reaction equilibrium that prevails at high reaction temperatures, only very small amounts of methane and mainly carbon monoxide and hydrogen are produced.

Die Erfindung gründet sich auf die Erkenntnis, daß die Umsetzung von vorwiegend aus den genannten paraffinischen Kohlenwasserstoffen bestehenden Mischungen mit Wasserdampf in zufriedenstellender Weise bei einer Temperatur in dem Bereich von 400 bis 550° C ohne die Notwendigkeit einer Wärmezufuhr von außen oder einer besonderen Wärmeerzeugung im Reaktionsraum ausgeführt werden kann, wenn die Kohlenwasserstoffe und der Wasserdampf auf einer Temperatur über 350° C vorerhitzt werden, und daß die auf diese Weise unmittelbar erhaltenen Gase vergleichsweise reich an Methan sind, da sie beispielsweise mehr als 50 Volumprozent Methan nach Entfernung von Kohlendioxyd und Wasserdampf aus dem erhaltenen Gasgemisch enthalten. The invention is based on the knowledge that the implementation of predominantly from the above paraffinic hydrocarbons existing mixtures with water vapor in a more satisfactory manner Way at a temperature in the range of 400 to 550 ° C without the need for heat from the outside or a special heat generation in the reaction chamber can if the hydrocarbons and the water vapor are preheated to a temperature above 350 ° C and that the gases obtained directly in this way are comparatively rich in methane are because they are, for example, more than 50 percent by volume after removal of carbon dioxide and methane Contain water vapor from the gas mixture obtained.
Bei Versuchen, die Kohlenwasserstoff-Wasserdampf-Reaktion bei Temperaturen unter 900 und über 550° C auszuführen, wurde festgestellt, daß sich auf dem Katalysator wesentliche Mengen an Kohlenstoff abscheiden, sofern nicht ein großer Überschuß von Wasserdampf verwendet wird. Die Abscheidung von Kohlenstoff verschlechtert die Wirkung des Katalysators und verstopft die Apparatur.When attempting the hydrocarbon-water vapor reaction at temperatures below 900 and Carry out above 550 ° C, it was found that there are significant amounts of on the catalyst Separate carbon unless a large excess of water vapor is used. the Deposition of carbon worsens the effectiveness of the catalyst and clogs the apparatus.
Wenn die Abscheidung von Kohlenstoff durch Wasserdampf verhindert werden soll, sind sehr große Mengen von Wasserdampf (etwa 100 Gewichtsteile Wasserdampf je 1 Gewichtsteil Kohlenwasserstoff) erforderlich, welche das Verfahren unwirtschaftlich und technisch unbrauchbar machen.If the deposition of carbon by water vapor is to be prevented, they are very large Amounts of water vapor (about 100 parts by weight of water vapor per 1 part by weight of hydrocarbon) required, which make the process uneconomical and technically unusable.
Bei dem Verfahren gemäß der Erfindung Wird die Ablagerung von Kohlenstoff durch Verwendung von Anteilen an Wasserdampf innerhalb der vorstehend angegebenen Bereiche vermieden, so daß kein großer Überschuß von Wasserdampf erforderlich ist.In the method according to the invention, the deposition of carbon is carried out by using Contents of water vapor avoided within the ranges given above, so that no large Excess of steam is required.
Die Temperatur, auf die der Kohlenwasserstoffdampf und der Wasserdampf vorerhitzt werden müssen, um das Katalysatorbett auf einer Temperatur in dem erfindungsgemäß anzuwendenden Bereich zu halten, hängt von den relativen Anteilen der Kohlenwasserstoffe und des Wasserdampfes und von dem Druck ab, bei dem das Verfahren ausgeführt wird. Die Vorerhitzungstemperatur soll je-The temperature to which the hydrocarbon vapor and water vapor are preheated have to keep the catalyst bed at a temperature in the range to be used according to the invention to keep depends on the relative proportions of hydrocarbons and water vapor and on the pressure at which the procedure is carried out. The preheating temperature should
doch immer über 350° C, um eine ausreichende Aktivität des Katalysators zu gewährleisten, und zweckmäßig unter 500° C liegen, um eine vorzeitige thermische Zerlegung der Kohlenwasserstoffe zu vermeiden. but always above 350 ° C to ensure sufficient activity of the catalyst, and expediently below 500 ° C in order to avoid premature thermal decomposition of the hydrocarbons.
Der Druck kann bis zu 50 at betragen, jedoch kann er gewünschtenfalls auch höher sein. Geeignete Drücke liegen in dem Bereich von 10 bis 25 at.The pressure can be up to 50 atm, but it can also be higher if desired. Suitable Pressures are in the range of 10 to 25 at.
Je niedriger die Temperatur des Katalysatorbettes ist, um so höher ist der Methangehalt in dem erzeugten Gas, und je höher der Druck ist, um so höher ist der Methangehalt. Das erzeugte Gas enthält nach der Entfernung von Kohlendioxyd und Wasserdampf aus ihm im allgemeinen wenigstens 50 Volumprozent Methan, und die Konzentration an Methan kann bei verhältnismäßig hohem Druck, wie z. B. 50 at, 80 Volumprozent übersteigen.The lower the temperature of the catalyst bed, the higher the methane content in the product Gas, and the higher the pressure, the higher the methane content. The generated gas contains after the removal of carbon dioxide and water vapor from it generally at least 50 percent by volume Methane, and the concentration of methane can be at relatively high pressure, such as. B. 50 at, Exceed 80 percent by volume.
Der bei der Kohlenwasserstoff-Wasserdampf-Reaktion benutzte Katalysator besteht aus mit Aluminiumoxyd (Tonerde) aktiviertem reduziertem Nickel und enthält beispielsweise 15% Nickel. Ein solcher Katalysator kann in bekannter Weise bereitet werden, indem man eine wäßrige Lösung von wasserlöslichen Salzen, wie den Nitraten, von Nickel und Aluminium mit einem Alkali, wie Natriumcarbonat, behandelt, um einen Niederschlag eines Gemisches von Nickel- und Aluminiumverbindungen zu erzeugen, den Niederschlag wäscht und trocknet, die Nickelverbindung zu metallischem Nickel reduziert und das sich ergebende Gemisch von reduziertem Nickel und Tonerde in Korn- oder Tablettenform bringt. Gegegebenenf alls kann man Körner von aktivierter Tonerde mit einer wäßrigen Lösung von Nickelnitrat imprägnieren und dann rösten und das Nickeloxyd zu metallischem Nickel reduzieren.The one in the hydrocarbon-water vapor reaction The catalyst used consists of reduced nickel and activated with aluminum oxide (alumina) for example contains 15% nickel. Such a catalyst can be prepared in a known manner by an aqueous solution of water-soluble salts, such as the nitrates, of nickel and aluminum treated with an alkali such as sodium carbonate to produce a precipitate of a mixture of nickel and to produce aluminum compounds, the precipitate washes and dries the nickel compound reduced to metallic nickel and the resulting mixture of reduced nickel and Brings clay in grain or tablet form. Given All activated alumina grains can be impregnated with an aqueous solution of nickel nitrate and then roast and reduce the nickel oxide to metallic nickel.
