Description
Verfahren zum Erzeugen von methanhaltigen Gasen 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. Erdöldestillation.Method for generating methane-containing gases The invention relates to focus on 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 distillation.
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 Wasserstoff 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 points To produce hydrocarbons containing sulfur as an impurity by that the vapor of the hydrocarbons with water vapor in the presence of a nickel catalyst at temperatures between about 870 and 1040 ° C to form a mixture that is im consists essentially of hydrogen and carbon monoxide, converts the mixture through a sulfur adsorber or scrubber leads and the purified mixture to the formation of methane at temperatures between 260 and 482'C with a nickel catalyst in Brings touch. The known multi-stage process has the disadvantage that in the first stage a special supply of heat is required, since the conversion of the hydrocarbons endothermic with hydrogen to form a mixture of hydrogen and carbon monoxide is. For this purpose either oxygen must be supplied to the first stage, to release heat by combustion in the reaction zone, or it is a special one External heating of the catalyst provided in a large number of tubes is required. Such working methods with the generation of heat or with special heat supply are costly both in terms of operation and the equipment required and uneconomical.
Es ist ferner ein Verfahren bekannt, gemäß welchem aus Dieselöl und Kerosin Ölgas (hauptsächlich H2, CH, C,H4 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 erhalten.A method is also known according to which oil gas (mainly H2, CH, C, H4 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 water vapor. In this procedure, in accordance with the reaction equilibrium prevailing at high reaction temperatures, only very small amounts of methane and mainly carbon monoxide and hydrogen are obtained.
Gemäß der Erfindung werden methanhaltige Gase aus Mischungen von vorwiegend paraffinischen Kohlenwasserstoffen, die im Mittel 4 bis 10 Kohlenstoff atome enthalten, in einem Verfahren erzeugt, bei welchem der Dampf der Kohlenwasserstoffe und Wasserdampf im Verhältnis von 2 bis 5 Gewichtsteilen Dampf auf 1 Gewichtsteil der Kohlenwasserstoffe oder bei Verwendung von Kohlenwasserstoffen, die im Mittel 4 bis 7 Kohlenstoffatome enthalten, im Verhältnis von 1,5 bis 5 Gewichtsteilen Dampf auf 1 Gewichtsteil der Kohlenwasserstoffe durch ein Bett aus einem Nickelkatalysator bei Atmosphärendruck oder bei Überatmosphärendruck geführt und der Kohlenwasserstoffdampf und der Wasserdampf in das Katalysatorbett bei einer Temperatur über 350°C geleitet werden, so daß das Bett durch die Reaktion auf einer Temperatur in dem Bereich von 400 bis 550° C gehalten wird. Sofern ein methanärmeres Gas erzeugt werden soll, wird das Erdgas anschließend mit Kohlenmonoxyd und Wasserstoff verdünnt oder der Wirkung eines Nickelkatalysators bei einer Temperatur über 550°C unterworfen. Soll ein methanreiches Gas erzeugt werden, wird das Erdgas der Wirkung eines Nickelkatalysators bei einer Temperatur unter -400°C unterworfen.According to the invention methane-containing gases from mixtures of predominantly paraffinic hydrocarbons, which contain an average of 4 to 10 carbon atoms, generated in a process in which the steam is the hydrocarbons and water vapor in the ratio of 2 to 5 parts by weight of steam to 1 part by weight of the hydrocarbons or when using hydrocarbons with an average of 4 to 7 carbon atoms contain, in the ratio of 1.5 to 5 parts by weight of steam to 1 part by weight of the Hydrocarbons through a bed of a nickel catalyst at atmospheric pressure or at above atmospheric pressure and the hydrocarbon vapor and the water vapor be passed into the catalyst bed at a temperature above 350 ° C, so that the Bed held by the reaction at a temperature in the range of 400 to 550 ° C will. If a low-methane gas is to be produced, the natural gas is then used diluted with carbon monoxide and hydrogen or the action of a nickel catalyst subjected at a temperature above 550 ° C. Is supposed to produce a methane-rich gas the natural gas becomes the action of a nickel catalyst at a temperature subjected to below -400 ° C.
Die Erfindung gründet sich auf die Erkenntnis, daß die Umsetzung von vorwiegend aus den genannten paraffinischen -Kohlenwassemtoffent bestehenden Mischungen mit Wasserdampf in zufriedenstellender Weise bei einer Temperatur in dem Bereich von 350 bis 550`C ohne die Notwendigkeit einer Wärmezufuhr von außen oder einer besonderen Wärmeerieugung im Reaktionsraum ausgeführt werden kann, wenn die Kohlenwasserstof% 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 lbeg'pielsW'eise mehr als 50 Volumprozent Methan nach'Entfernung von Kohlendioxyd und Wasserdampf aua ...em .ehaltenen Gasgemisch enthalten.The invention is based on the knowledge that the implementation of predominantly consisting of the paraffinic hydrocarbon mixtures mentioned with water vapor satisfactorily at a temperature in the range from 350 up to 550`C without the need for an external heat supply or a special heat radiation in the reaction space can be carried out if the hydrocarbon% and the water vapor are preheated to a temperature above 350 ° C be,., and that the gases directly obtained in this way, comparatively are rich in methane, since they typically contain more than 50 percent by volume of methane after removal contain carbon dioxide and water vapor as well as a retained gas mixture.
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. 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.When trying the hydrocarbon-water vapor reaction at temperatures Running below 900 and above 550 ° C was found to be on the catalyst deposit substantial amounts of carbon, unless a large excess used by steam. The deposition of carbon worsens the Action of the catalyst and clogs the equipment. When the deposition of carbon to be prevented by water vapor 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 by using proportions of water vapor within those specified above Areas avoided so that a large excess of water vapor is not 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 jedoch 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.The temperature at which the hydrocarbon vapor and water vapor must be preheated to the catalyst bed to a temperature in the invention The range to be used depends on the relative proportions of hydrocarbons and the water vapor and pressure at which the process is carried out. However, the preheating temperature should always be above 350 ° C in order to achieve sufficient activity to ensure the catalyst; and expediently below 500 ° C to prevent premature to avoid 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 if desired also be higher. Suitable pressures are in the range of 10 to 25 at.
Je niedriger die Temperaturdes Katalysato)7bettes 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 Volümprozent Methan, und die- Konzentration an Methan -kann bel verhältnismäßig hohem Druck;. wie z. B. 50 at, 80 Volumprozent übersteigen.The lower the temperature of the catalyst bed, the higher is the. Methane content in the gas produced, and the higher the pressure, the higher is the methane content. The generated gas contains after removal of carbon dioxide and water vapor from it in general - at least 50 percent by volume methane, and The concentration of methane can be used at a relatively high pressure. such as B. 50 at, exceed 80 percent by volume.
Das so erhaltene inethanreiche Gas kann für die Verdünnung mit einem Gas, welches hauptsächlich aus Kohlenmonoxyd und Wasserstoff besteht, verwendet werden, um ein brennbares Gas mit einem geringeren Methangehalt, beispielsweise ein Stadtgas .mit einem Heizwert von 4000 bis 4450 kcal/m3 zu erzeugen.The inethane-rich gas thus obtained can be diluted with a Gas, which consists mainly of carbon monoxide and hydrogen, is used be to a flammable gas with a lower methane content, for example to generate a town gas with a calorific value of 4000 to 4450 kcal / m3.
Gegebenenfalls kann ein nach dem Verfahren gemäß der Erfindung erzeugtes methanreiches Gas in ein Gas mit einem niedrigeren Methangehalt, z. B. in ein Stadtgas dadurch umgewandelt werden, daß das methanreiche Gas der Wirkung eines Nickelkatalysators bei einer solchen Temperatur oberhalb von 550'C unterworfen wird, daß die Umwandlung von Methan durch" die Reaktion mit Wasserdampf zu Kohlenmonoxyd und ,Wasserstoff in dein Ausmaß herbeigeführt wird, welches erforderlich ist, um den Methangehalt auf den gewünschten Wert herabzusetzen. Da diese Umwandlung endotherm ist, muß Wärme zugeführt werden, um die Reaktion aufrechtzuerhalten. Dies kann beispielsweise dadurch bewirkt werden, daß Rohre, welche den Katalysator enthalten, von außen erhitzt werden oder daß Sauerstoff für die Verbrennung in der Reaktionszone eingeführt wird. Für diesen Zweck kann Luft verwendet werden, wenn der dabei in das Gas eingebrachte Stickstoff nicht unerwünscht ist.Optionally, one produced by the method according to the invention can be used methane-rich gas into a gas with a lower methane content, e.g. B. in a town gas can be converted by letting the methane-rich gas act as a nickel catalyst is subjected at such a temperature above 550'C that the conversion of methane through "the reaction with water vapor to carbon monoxide and, hydrogen is brought about to the extent that is necessary to reduce the methane content to the desired value. Since this transformation is endothermic, heat must be used can be added to maintain the reaction. This can be done, for example caused pipes containing the catalyst to be heated from the outside or that oxygen is introduced for combustion in the reaction zone. For Air can be used for this purpose, if it is introduced into the gas Nitrogen is not undesirable.
Andererseits kann, wenn ein Gas mit einem höheren Methangehalt gewünscht wird, das nach dem Verfahren gemäß der Erfindung erzeugte methanreiche Gas der Wirkung eines Nickelkatalysators bei einer niedrigeren Temperatur, z. B. bei 400°C oder darunter, unterworfen werden, um die Bildung von Methan, durch die Reaktion zwischen Kohlendioxyd, Kohlenmonoxyd und Wasserstoff, die in dem Gas vorhanden sind, herbeizuführen.On the other hand, if a gas with a higher methane content is desired becomes, the methane-rich gas of action produced by the method according to the invention a nickel catalyst at a lower temperature, e.g. B. at 400 ° C or including, are subjected to the formation of methane, by the reaction between To bring about carbon dioxide, carbon monoxide and hydrogen present in the gas.
Die nachfolgenden katalytischen Behandlungen -des Gases zur Erzeugung eines Gases mit einem niedrigeren oder höheren Methangehalt können bei Atmosphärendruck oder bei einem über Atmosphärendruck liegenden Druck ausgeführt werden, und sie werden zweckmäßig im allgemeinen im wesentlichen unter dem gleichen Druck ausgeführt wie die Kohlenwasserstoff-Wasserdampf-Reaktion.The subsequent catalytic treatments - the gas for generation of a gas with a lower or higher methane content can be used at atmospheric pressure or at a pressure above atmospheric pressure, and they are conveniently generally carried out under substantially the same pressure like the hydrocarbon-water vapor reaction.
Der bei der Kohlenwasserstoff-Wasserdampf-Reaktion und bei den nachfolgenden Behandlungen des methanreichen Gases benutzte Katalysator besteht vorzugsweise aus mit Aluminiumoxyd (Tonerde) aktiviertem reduzierten Nickel und enthält beispielsweise 150/, 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 Toneide in Korn- oder Tablettenform bringt. Gegebenenfalls, kann man Körner von aktivierter Tonerde mit einer wärigen Lösung von - Nickelnitrat imprägnieren und;dann rösten und das Nickeloxyd zu metallischem, Nickel reduzieren.The catalyst used in the hydrocarbon-steam reaction and in the subsequent treatments of the methane-rich gas preferably consists of reduced nickel activated with aluminum oxide (alumina) and contains, for example, 150 % nickel. Such a catalyst can be prepared in a known manner by treating an aqueous solution of water-soluble salts, such as the nitrates, of nickel and aluminum with an alkali, such as sodium carbonate, in order to produce a precipitate of a mixture of nickel and aluminum compounds, the precipitate washes and dries, the nickel compound is reduced to metallic nickel, and the resulting mixture of reduced nickel and clays is made into granules or tablets. If necessary, grains of activated alumina can be impregnated with a warm solution of - nickel nitrate and then roasted and the nickel oxide reduced to metallic nickel.
