Method and a device for generating a carburizing gas mixture

A method for generating a ternary carburizing gas mixture, the method comprising:

• removing atmosphere from inside a reactor, the inside of the reactor containing a layer of a regiospecific hydrogenation catalyst comprising palladium or platinum,
• heating the inside of the reactor to an operating temperature of the catalyst with heated inert gas,
• hydrogenating at least a portion of a reactant mixture consisting of 45 to 55% hydrogen and 55 to 45% acetylene, respectively, in the presence of the regiospecific catalyst to selectively catalyze the hydrogenation of a portion of the acetylene into ethylene and produce the carburizing gas mixture, and
• removing the ternary carburizing gas mixture from the reactor;
• wherein:
• generating the ternary carburizing gas mixture is carried out in a continuous mode at an operating temperature range of the regiospecific catalyst between 293 K and 398 K;
• and
• the generated ternary carburizing gas mixture has a ratio of acetylene to ethylene in a range of 0.6 to 2.0.
