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 feinstückige Elektrodenkohle geleitet wird.Process for the production of acetylene from methane or other gaseous hydrocarbons The patent 501 179 describes a process for the production of acetylene from methane or natural gas, which consists in that the possibly preheated gas is passed in an electric furnace over fine-piece electrode carbon connected as a resistor will.

Es wurde nunmehr gefunden, daß die Ausbeute an Acetylen verbessert werden kann, wenn man für die Widerstandsheizung ein Material verwendet, das den zur Reaktion zu bringenden Gasen :eine besonders große Berührungsfläche bietet, und zwar ist jedes poröse Material geeignet, das den in Frage stehenden Temperaturen (r q.oo bis 2ooo° C-) standhält. Insbesondere kann also z. B. poröse Kohle oder ein entsprechendes anderes kohlehaltiges oder ein nach den bekannten Verfahren leitend gemachtes Material Verwendung finden. Beispiel I Ein elektrischer Widerstandsofen, wie er im Patent Sor 179 beschrieben und abgebildet ist, wurde statt mit kleinstücltiger Elektrodenkohle mit gut ausgeglühtem Steinkohlenkoks als Widerstandsmaterial gefüllt und bei r 8oo° C ein Gas von etwa 98 % Methan mit einer Durchströrnungsdauer von 1/20o Sekunde hindurchgeführt. Es wurde ein Reaktionsgas mit 19,5 % Acetylenerhalten; es sind also rund 75 % Methan umgesetzt worden. Beispiel 11 In genau gleicher Weise wurde mit einem Widerstandsmaterial gearbeitet, das durch Pressen, Glühen und Zerkleinern eines ölhaltigen Breies aus 25 % Siliciumcarbid und 75 % Kohle hergestellt worden war. Es wurde ebenfalls ein Reaktionsgas mit 18,5 % Acetylen erhalten.It has now been found that the yield of acetylene can be improved if a material is used for the resistance heating which offers the gases to be reacted: a particularly large contact surface, and any porous material is suitable, which is the one in question Withstands temperatures (rq.oo to 2ooo ° C-). In particular, z. B. porous coal or a corresponding other carbon-containing material or a material made conductive according to the known method can be used. Example I An electrical resistance furnace, as described and illustrated in the Sor 179 patent, was filled with well-annealed hard coal coke as resistance material instead of with small pieces of electrode carbon and a gas of about 98% methane with a flow time of 1/20 of a second at r 800 ° C passed through. A reaction gas containing 19.5% acetylene was obtained; So around 75% methane has been converted. EXAMPLE 11 In exactly the same way, a resistor material was used which had been produced by pressing, annealing and comminuting an oily slurry of 25% silicon carbide and 75% carbon. A reaction gas containing 18.5% acetylene was also obtained.
