Description
Verfahren zur Herstellung von Acetylen aus Methan oder anderen gasförmigen Kohlenwasserstoffen Im. Patent 501 179 ist ein Verfahren zur Herstellung von Acetylen aus Methan bzw. Naturgas beschrieben, welches darin besteht, daß das gegebenenfalls vorgewärmte Gas in einem .elektrischen Ofen über als Widerstand geschaltete feinstücldge Elektrodenkohle geleitet wird. Es ist ferner bereits vorgeschlagen worden, dieses Verfahren dadurch zu verbessern, daß die feinstückige Elektrodenkohle durch solche Widerstandsmaterialien ersetzt wird, welche eine große innere Oberfläche aufweisen, wie z. B. Koks, poröse Kohle, Carbide u. dgl.Process for the production of acetylene from methane or other gaseous hydrocarbons In the. Patent 501 179 a process for the production of acetylene from methane or natural gas is described, which consists in that the optionally preheated gas in an .electric furnace via fine electrode carbon connected as a resistor is directed. It has also already been proposed to improve this method in that the fine-piece electrode carbon is replaced by such resistance materials which have a large inner surface, such as. B. coke, porous coal, carbides and the like.
Es wurde nunmehr gefunden, daß bei all diesen genannten Verfahren die Gefahr einer Luizulässigen Kohleabscheidung vermieden, die Ausbeute erhöht und ein ununterbrochener Betrieb der Öfen erreicht werden kann, wenn man die Reaktionsgase unter vermindertem Druck durch die Öfen hindurchführt, oder wenn man, was entsprechend den physikalischen Gesetzen auf das gleiche hinauskommt, den Partialdruck der zu zersetzenden Kohlenwässerstoffe durch Zumischung von Wasser-§toff erniedrigt.It has now been found that in all of these processes mentioned Avoided the risk of a permissible coal deposition, increased the yield and Uninterrupted operation of the furnace can be achieved if the reaction gases are removed passes through the ovens under reduced pressure, or if you can, what corresponding the laws of physics come to the same thing, the partial pressure of the decomposing hydrocarbons are reduced by adding water.
Beispiel I Durch einen elektrischen Widerstandsofen wurde ein Gas mit 98,5-% Methan (Rest Wasserstoff und Stickstoff) bei einem Druck von 1/1o Atm., bei einer Temperatur von i8oo° C und einer Durchströmungsdauer von 1/1oo Sekunde geleitet. Es entstand :ein Reaktionsgas mit 21,25 % Acetylen, was einer Ausbeute von 85 % entspricht. Der Rest bestand aus Wasserstoff und etwas nicht umgewandeltemMethan. Aoetylenpolymere waren nicht vorhanden. Stromverbrauch 115 % der Theorie.Example I A gas was passed through an electric resistance furnace with 98.5% methane (remainder hydrogen and nitrogen) at a pressure of 1/10 atm., at a temperature of 180 ° C and a flow time of 1/100 second directed. The result was: a reaction gas with 21.25% acetylene, which is a yield of 85%. The remainder consisted of hydrogen and some unconverted methane. Ethylene polymers were not present. Power consumption 115% of theory.
Beispiel II Ein Gasgemisch mit 5o % Methan und 5o % Wasserstoff wurde im gleichen Ofen bei 1/1o Atm., bei i 8oo° C und mit 1/20o Sekunde Durchströmungsdauer behandelt. Das Endgas enthielt 15,75 0i'o Acetylen. Ausbeute also 95 %. Keine Polymere des Acetylens. Beispiel III Im gleichen Ofen wurde ein Gas folgender Zusammensetzung behandelt: 55 % Methan, 15'/, Äthan, io % Äthylen und 200/, Wasserstoff. Druck 1/1o Atm., Temperatur i85 o° C, Durchströmungsdauer 1/ioo Sekunde. Das Endgas enthielt 23,75 % Acetylen, keine Polymere.Example II A gas mixture with 50% methane and 50% hydrogen was treated in the same furnace at 1/10 atm., At 1800 ° C. and with a flow rate of 1/20 of a second. The tail gas contained 15.75 % acetylene. So the yield is 95%. No polymers of acetylene. EXAMPLE III A gas of the following composition was treated in the same furnace: 55% methane, 15% ethane, 10% ethylene and 200% hydrogen. Pressure 1/10 atm., Temperature 85 ° C, flow duration 1/100 second. The tail gas contained 23.75% acetylene, no polymers.
