Claim Text:
1. 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.
